Assignment 2: Tests of Significance
Throughout this assignment you will review mock studies. You will needs to follow the directions outlined in the section using SPSS and decide whether there is significance between the variables. You will need to list the five steps of hypothesis testing (as covered in the lesson for Week 6) to see how every question should be formatted. You will complete all of the problems. Be sure to cut and past the appropriate test result boxes from SPSS under each problem and explain what you will do with your research hypotheses. All calculations should be coming from your SPSS. You will need to submit the SPSS output file to get credit for this assignment. This file will save as a .spv file and will need to be in a single file. In other words, you are not allowed to submit more than one output file for this assignment.
The five steps of hypothesis testing when using SPSS are as follows:
1. State your research hypothesis (H1) and null hypothesis (H0).
2. Identify your confidence interval (.05 or .01)
3. Conduct your analysis using SPSS.
4. Look for the valid score for comparison. This score is usually under ‘Sig 2-tail’ or ‘Sig. 2’. We will call this “p”.
5. Compare the two and apply the following rule:
a. If “p” is < or = confidence interval, than you reject the null.
Be sure to explain to the reader what this means in regards to your study. (Ex: will you recommend counseling services?)
* Be sure that your answers are clearly distinguishable. Perhaps you bold your font or use a different color.
ASSIGNMENT 2(200) WORD MINIUM
1. They allow us to see if our relationship is "statistically significant". (Remember that this only shows us that there is or is not a relationship but does NOT show us if it is big, small, or in-between.)
2. It let's us know if our findings can be generalized to the population which our sample was selected from and represents.
This week you will decide which test of significance you will use for your project. For this class your choices for tests will include one of the following:
· Chi-square
· t Test
· ANOVA
We will be using a process for hypothesis testing which outlines five steps researchers can follow to complete this process:
1. Write your research hypothesis (H1) and your null hypothesis (H0).
2. Identify and record your confidence interval. These are usually .05 (95%) or .01 (99%).
3. Complete the test using SPSS.
4. Identify the number under Sig. (2-tail). This will be represented by "p".
5. Compare the numbers in steps 2 and 4 and apply the following rule:
1. If p < or = confidence interval, than you reject the null hypothesis
Determine what to do with your null and explain this to your reader. Be sure to go beyond the phrase "reject or fail to reject the null" and explain how that impacts your research and best describes the relationship between variables.

A psychotherapist studied whether his clients self-disclosed more while sitting in an easy chair or lying down on a couch. All clients had previously agreed to allow the sessions to be videotaped for research purposes. The therapist randomly assigned 10 clients to each condition. The third session for each client was videotaped and an independent observer counted the clients’ disclosures. The therapist reported that “clients made more disclosures when sitting in easy chairs (
M
= 18.20) than when lying down on a couch (

For the following question(s): A school counselor tests the level of depression in fourth graders in a particular class of 20 students. The counselor wants to know whether the kind of students in this class differs from that of fourth graders in general at her school. On the test, a score of 10 indicates severe depression, while a score of 0 indicates no depression. From reports, she is able to find out about past testing. Fourth graders at her school usually score 5 on the scale, but the variation is not known. Her sample of 20 fifth graders has a mean depression score of 4.4. Use the .01 level of significance.
1.
The counselor calculates the unbiased estimate of the population’s variance to be 15. What is the variance of the distribution of means?
A)
15/20 = 0.75
B)
15/19 = 0.79
C)

2.
Suppose the counselor tested the null hypothesis that fourth graders in this class were
less
depressed than those at the school generally. She figures her
t
score to be
-
.20. What decision should she make regarding the null hypothesis?
A)
Reject it
B)
Fail to reject it
C)
Postpone any decisions until a more conclusive study could be conducted
D)
There is not enough information given to make a decision
3.
Suppose the standard deviation she figures (the square root of the unbiased estimate of the population variance) is .85. What is the effect size?
A)
5/.85 = 5.88
B)
.85/5 = .17
C)
(5
-
4.4)/.85 = .71
D)
.85/(5

For the following question(s): Professor Juarez thinks the students in her statistics class this term are more creative than most students at this university. A previous study found that students at this university had a mean score of 35 on a standard creativity test. Professor Juarez finds that her class scores an average of 40 on this scale, with an estimated population standard deviation of 7. The standard deviation of the distribution of means comes out to 1.63.
4.
What is the
t
score?
A)
(40

ANOVA is a hypothesis testing technique used to compare the equality of means for two or more groups; for example, it can be used to test that the mean number of computer chips produced by a company on each of the day, evening, and night shifts is the same. Give an example of an application of ANOVA in an industrial, operations, or manufacturing setting that is different from the examples provided in the overview. Discuss and share this information with your classmates.
In responding to your peers, select responses that use an ANOVA application that is different from your own. Are the results of the ANOVA application statistically significant? Why are the results significant or not significant? Explain your reasoning. Consider how ANOVA could be applied to the final project case study.

PLEASE GIVE A 1-2 PARAGRAPH RESPONSE TO THE FOLLOWING:
1.
In this module, our goal is to learn the statistical process of comparing several population means through a procedure called "analysis of variance", or ANOVA. ANOVA uses the variance from the mean of 2 or more sample populations to see if there is a statistically significant difference between them (Sharpe, DeVeaux, Velleman, 2016). We've learned that this is a valuable tool in all sorts of areas of study, including automotive, chemical, and medical industries.
There are many practical examples of ANOVA throughout business. As previously mentioned, the medical field can benefit from the use of this statistics tool. For example, a drug company may be interested in the results of clinical trials for a few new drugs they plan to release. Medicine A, B, and C are all now in the clinical testing phase, so the instances in which each cures a specific ailment can be summed up using ANOVA. Each of the individual drugs, through the course of multiple trials, will have a number of "cured" patients. The following is an example of what the results may be, in table format:
A B C
Trial 1 4 9 2
2 5 8 7
3 7 1 6
4 6 1 5
5 6 4 9
Using ANOVA to evaluate the variance from the mean for each trial, the ultimate goal would be to compare each trial to one another. By comparing the variance, we can say, with statistical confidence, that one medicine may be more effect.

STEP #1
Check what measurement level your DV is.
STEP #2
Choose the column related to the number Groups in your study.
STEP #3
Choose the column where intervention groups are either “paired” or “unpaired.”
STEP #4
Match your column with the row to find which test
to run.
STEP #1
Look at your Dependent Variable or outcome.
The data that we are looking at here is from the instruments you used to measure the effect of your intervention. Maybe you chose to measure stress with a commonly used psychological questionnaire or maybe you measured cholesterol levels or test scores.
What is its measurement level?
Categorical (such as yes or no; dead or alive; pass or fail).
Ordinal (such as health status – poor, average, excellent).
Interval ratio (for instance blood pressure, cholesterol level, rates of infection, or workplace satisfaction scores on a scale of 0-100).
STEP #2
Next you will look for the column that corresponds to the number of groups you have for your Independent Variable (also called experimental or predictor variable).
Remember, the independent variable is the thing in your study that was controlled by you (such as a medical intervention, or training initiative, or implementation of a modified protocol) for the purpose of making a change on some outcome in the population you are studying.
So…how many groups were involved in this intervention?
For example, if you were testing the effect of an evidence-based training initiative on employee workplace satisfaction or happiness, you might be interested in comparing the training initiative in one group to no training in another group..

Hypothesis Testing Definitions A statistical hypothesi.docxwilcockiris
Hypothesis Testing
Definitions:
A statistical hypothesis is a guess about a population parameter. The guess may or not be
true.
The null hypothesis, written H0, is a statistical hypothesis that states that there is no
difference between a parameter and a specific value, or that there is no difference between
two parameters.
The alternative hypothesis, written H1 or HA, is a statistical hypothesis that specifies a
specific difference between a parameter and a specific value, or that there is a difference
between two parameters.
Example 1:
A medical researcher is interested in finding out whether a new medication will have
undesirable side effects. She is particularly concerned with the pulse rate of patients who
take the medication. The research question is, will the pulse rate increase, decrease, or
remain the same after a patient takes the medication?
Since the researcher knows that the mean pulse rate for the population under study is 82
beats per minute, the hypotheses for this study are:
H0: µ = 82
HA: µ ≠ 82
The null hypothesis specifies that the mean will remain unchanged and the alternative
hypothesis states that it will be different. This test is called a two-tailed test since the
possible side effects could be to raise or lower the pulse rate. Notice that this is a non
directional hypothesis. The rejection region lies in both tails. We divide the alpha in two
and place half in each tail.
Example 2:
An entrepreneur invents an additive to increase the life of an automobile battery. If the
mean lifetime of the automobile battery is 36 months, then his hypotheses are:
H0: µ ≤ 36
HA: µ > 36
Here, the entrepreneur is only interested in increasing the lifetime of the batteries, so his
alternative hypothesis is that the mean is greater than 36 months. The null hypothesis is
that the mean is less than or equal to 36 months. This test is one-tailed since the interest
is only in an increased lifetime. Notice that the direction of the inequality in the alternate
hypothesis points to the right, same as the area of the curve that forms the rejection
region.
Example 3:
A landlord who wants to lower heating bills in a large apartment complex is considering
using a new type of insulation. If the current average of the monthly heating bills is $78,
his hypotheses about heating costs with the new insulation are:
H0: µ ≥ 78
HA: µ < 78
This test is also a one-tailed test since the landlord is interested only in lowering heating
costs. Notice that the direction of the inequality in the alternate hypothesis points to the
left, same as the area of the curve that forms the rejection region.
Study Design:
After stating the hypotheses, the researcher’s next step is to design the study. In designing
the study, the researcher selects an appropriate statistical test, chooses a level of
significance, and formulates a plan for conducting the study..

For the following question(s): A school counselor tests the level of depression in fourth graders in a particular class of 20 students. The counselor wants to know whether the kind of students in this class differs from that of fourth graders in general at her school. On the test, a score of 10 indicates severe depression, while a score of 0 indicates no depression. From reports, she is able to find out about past testing. Fourth graders at her school usually score 5 on the scale, but the variation is not known. Her sample of 20 fifth graders has a mean depression score of 4.4. Use the .01 level of significance.

ANOVA is a hypothesis testing technique used to compare the equality of means for two or more groups; for example, it can be used to test that the mean number of computer chips produced by a company on each of the day, evening, and night shifts is the same. Give an example of an application of ANOVA in an industrial, operations, or manufacturing setting that is different from the examples provided in the overview. Discuss and share this information with your classmates.
In responding to your peers, select responses that use an ANOVA application that is different from your own. Are the results of the ANOVA application statistically significant? Why are the results significant or not significant? Explain your reasoning. Consider how ANOVA could be applied to the final project case study.
Support your initial posts and response posts with scholarly sources cited in APA style.

PLEASE GIVE A 1-2 PARAGRAPH RESPONSE TO THE FOLLOWING:
1.
In this module, our goal is to learn the statistical process of comparing several population means through a procedure called "analysis of variance", or ANOVA. ANOVA uses the variance from the mean of 2 or more sample populations to see if there is a statistically significant difference between them (Sharpe, DeVeaux, Velleman, 2016). We've learned that this is a valuable tool in all sorts of areas of study, including automotive, chemical, and medical industries.
There are many practical examples of ANOVA throughout business. As previously mentioned, the medical field can benefit from the use of this statistics tool. For example, a drug company may be interested in the results of clinical trials for a few new drugs they plan to release. Medicine A, B, and C are all now in the clinical testing phase, so the instances in which each cures a specific ailment can be summed up using ANOVA. Each of the individual drugs, through the course of multiple trials, will have a number of "cured" patients. The following is an example of what the results may be, in table format:
A B C
Trial 1 4 9 2
2 5 8 7
3 7 1 6
4 6 1 5
5 6 4 9
Using ANOVA to evaluate the variance from the mean for each trial, the ultimate goal would be to compare each trial to one another. By comparing the variance, we can say, with statistical confidence, that one medicine may be more effect.

STEP #1
Check what measurement level your DV is.
STEP #2
Choose the column related to the number Groups in your study.
STEP #3
Choose the column where intervention groups are either “paired” or “unpaired.”
STEP #4
Match your column with the row to find which test
to run.
STEP #1
Look at your Dependent Variable or outcome.
The data that we are looking at here is from the instruments you used to measure the effect of your intervention. Maybe you chose to measure stress with a commonly used psychological questionnaire or maybe you measured cholesterol levels or test scores.
What is its measurement level?
Categorical (such as yes or no; dead or alive; pass or fail).
Ordinal (such as health status – poor, average, excellent).
Interval ratio (for instance blood pressure, cholesterol level, rates of infection, or workplace satisfaction scores on a scale of 0-100).
STEP #2
Next you will look for the column that corresponds to the number of groups you have for your Independent Variable (also called experimental or predictor variable).
Remember, the independent variable is the thing in your study that was controlled by you (such as a medical intervention, or training initiative, or implementation of a modified protocol) for the purpose of making a change on some outcome in the population you are studying.
So…how many groups were involved in this intervention?
For example, if you were testing the effect of an evidence-based training initiative on employee workplace satisfaction or happiness, you might be interested in comparing the training initiative in one group to no training in another group..

Hypothesis Testing Definitions A statistical hypothesi.docxwilcockiris
Hypothesis Testing
Definitions:
A statistical hypothesis is a guess about a population parameter. The guess may or not be
true.
The null hypothesis, written H0, is a statistical hypothesis that states that there is no
difference between a parameter and a specific value, or that there is no difference between
two parameters.
The alternative hypothesis, written H1 or HA, is a statistical hypothesis that specifies a
specific difference between a parameter and a specific value, or that there is a difference
between two parameters.
Example 1:
A medical researcher is interested in finding out whether a new medication will have
undesirable side effects. She is particularly concerned with the pulse rate of patients who
take the medication. The research question is, will the pulse rate increase, decrease, or
remain the same after a patient takes the medication?
Since the researcher knows that the mean pulse rate for the population under study is 82
beats per minute, the hypotheses for this study are:
H0: µ = 82
HA: µ ≠ 82
The null hypothesis specifies that the mean will remain unchanged and the alternative
hypothesis states that it will be different. This test is called a two-tailed test since the
possible side effects could be to raise or lower the pulse rate. Notice that this is a non
directional hypothesis. The rejection region lies in both tails. We divide the alpha in two
and place half in each tail.
Example 2:
An entrepreneur invents an additive to increase the life of an automobile battery. If the
mean lifetime of the automobile battery is 36 months, then his hypotheses are:
H0: µ ≤ 36
HA: µ > 36
Here, the entrepreneur is only interested in increasing the lifetime of the batteries, so his
alternative hypothesis is that the mean is greater than 36 months. The null hypothesis is
that the mean is less than or equal to 36 months. This test is one-tailed since the interest
is only in an increased lifetime. Notice that the direction of the inequality in the alternate
hypothesis points to the right, same as the area of the curve that forms the rejection
region.
Example 3:
A landlord who wants to lower heating bills in a large apartment complex is considering
using a new type of insulation. If the current average of the monthly heating bills is $78,
his hypotheses about heating costs with the new insulation are:
H0: µ ≥ 78
HA: µ < 78
This test is also a one-tailed test since the landlord is interested only in lowering heating
costs. Notice that the direction of the inequality in the alternate hypothesis points to the
left, same as the area of the curve that forms the rejection region.
Study Design:
After stating the hypotheses, the researcher’s next step is to design the study. In designing
the study, the researcher selects an appropriate statistical test, chooses a level of
significance, and formulates a plan for conducting the study..

Case 1: Family Loyalty vs. Meritocracy
A man was appointed president of the newly-acquired Philippine subsidiary of a large American company. He was reviewing the organization with the company's head of human resources. One thing the president noted was that the same names reoccurred frequently in several departments. "It is our tradition," commented the HR head. "Families take care of their own. If one family member gets a good job in a Philippine company, other members of the family apply to join that company and the first member there can help the whole family become successful by helping them get hired and by coaching them to be successful. The company benefits. Our costs of recruiting are lower, we know more about the people we hire, and the commitment to family success results in fewer performance and discipline problems because family members want to please their older relatives."
The president wondered how these practices would be regarded in a large American firm, and whether or not he should take action to change them.
1. Nepotism is not illegal, but is it ethical?
2. If the business is family-owned, does that make a difference?
3. How does national culture affect this discussion?
Case 2: Is the Two-Tier System Ethically Problematic
Employees at a cereal makers plant were “locked-out” from their jobs producing cereal for over 3 months. Company management and the union representing the employees reached a stalemate in negotiations resulting in the lockout. The union claims that the primary issue is the company’s demand of dramatically increasing the number of temporary workers, who would earn $6 less per hour and receive fewer benefits. Critics claim this effectively creates a two-tier system at the plant. Under the current agreement, the company may use temporary workers for up to 30% of the workforce, but the union claims the company is now pushing for 100%. The workers, who have had their health insurance suspended, fear that their jobs will either be replaced entirely by temporary workers, or they will be f ...
Barbara Corcoran Learns Her Heart’s True Desires In her.docxrock73
Barbara Corcoran Learns Her Heart’s True Desires
In her hilarious and lighthearted book, Shark Tales: How I Turned $1,000 Into a
Billion Dollar Business, Barbara Corcoran demonstrates the importance of knowing what
you really want out of life (Corcoran & Littlefield, 2011). As her title suggests, Barbara
founded her real estate company, The Corcoran Group, with only $1,000 and some big
dreams. Shortly after founding the company, Barbara took out a piece of paper and wrote
down some big goals for herself and the company. In 1978, she had only 14 sales agents
working for her, who earned a total of $250,000 in commissions. She set a goal of
doubling the number of agents and the commissions every year. So she put down 28 sales
people for 1979, 56 for 1980, and so on, all the way up to 1,792 salespeople in 1985 with
total commissions of $32,000,000. Barbara was amazed when she saw the fantastic sums
projected for 1985, and of course many people, when they see such amazing sums, would
dismiss the calculations as fantasy But as Barbara put it, she went to work the next day
hustling hard for her $32 million.
Real estate agents are paid largely by commission, which is about as close as you
can get to a pure form of contingent reward for performance. However, Barbara didn’t
rely solely on the commissions to motivate her workers. She threw theme parties and held
numerous social events to build a committed workforce. Good sales agents could always
move to another firm, but not every firm had Barbara’s positive attitude and fun-filled
atmosphere. In the early years of the firm, when money was tight, Barbara and her
relatives did the cooking for the outings and parties, and she found clever ways to
entertain people with skating parties and other lively activities. As the firm became larger
and more profitable, she even hired professional entertainers for the company’s midweek
picnics, which included elephant shows, daring rides on hot air balloons, horses, or
Harley Davidsons, etc. Barbara stated “I built my company on pure fun, and believe that
fun is the most underutilized motivational tool in business today. All of my best ideas
came when I was playing outside the office with the people I worked with” (Corcoran &
Littlefield, 2011, p. 283). What did she get in return for the fun atmosphere? She had the
“most profitable real estate company per person in the United States” (p. 284). By the
time she sold her agency in 2001, she had 1,000 agents working for her, and she had the
largest real estate agency in New York – clearly her motivational strategies attracted a
large number of productive employees.
Barbara Corcoran had sold her firm for $66 million. She thought that would make
her happy, but instead, it made her sad. Although she pretended to be happy with her new
wealth and freedom, she was “secretly miserable” (Corcoran & Littlefield, 2011, p. 232).
She had lost her purpose ...

IN Deepa Mehta’s words
I wanted desperately to make CRACKING INDIA into a film, a particular film, EARTH, which would be the second in my trilogy of the elements of Fire, Earth and Water.
Tracing Bapsi was no easy task but persevere we did and soon I was talking to Bapsi on the phone, hoping that the film rights to her book were still available. Two months later, thanks to David Hamilton's unwavering belief in the project, we owned the rights, had development funds, and I was sitting at my kitchen table, writing the screenplay of EARTH.
David and Anne Masson and I had worked together on FIRE and we re-assembled the team to begin the detailed planning of the production.
During this phase Bapsi became a friend and was exceedingly generous with information and old photographs. She would talk with me for hours about what it was like growing up in Lahore during those times. Lenny, after all, was based on Bapsi. In fact, Lenny was Bapsi.
The irony of our situation hasn't escaped Bapsi or myself. Bapsi is from Pakistan and now a US citizen. I'm from India and now living in Canada. If neither of us had moved from our respective homelands, the film just wouldn't have been possible. Pakistan and India, since the Partition of 1947, are sworn enemies. Not only have they fought three major wars against each other, but also, as I write this, both countries talk blithely about their nuclear capabilities and continue their militant aggression against each other across the still- disputed Kashmir border.
Fallen Women in the novel and film
Abducted women like Ayah and Hamdia, Lenny’s new nanny are viewed with suspicion from Lenny.
Page 226
“It isn’t a jail, Lenny baby…it’s a camp for fallen women.”
“What are fallen women?”
“Hai! The questions you ask! Your mother won’t like such talk…Now keep quiet”
“Are you a fallen woman?”
Fallen women – Abducted and raped women
In the aftermath of the 1947 declaration of Indian independence, the roughly drawn new state boundaries triggered what may have been the biggest migration in human history.
Historical consensus supports a figure of 12 million people displaced, although the BBC suggests figures as high as 14.5 million people. An undeclared civil war erupted as communities of Hindus, Muslims, and Sikhs fought one another to establish their own identities in their redefined homelands. And, in the process, the Indian government estimates, 83,000 women were abused and abducted. Others put the number even higher.
“Rather than being raped and abandoned,” Yasmin Khan writes in The Great Partition: The ...
Barriers of therapeutic relationshipThe therapeutic relations.docxrock73
Barriers of therapeutic relationship:
The therapeutic relationship between patient and nurse is often filled with barriers that can generate obstacles for the relationship and, in the end, the health system as a whole (Sfoggia et al.,2014). There are many factors that hinder building a therapeutic relationship: language, professional jargon, communication impairment, and cultural diversity (ibid).
Language:
Language can be an obstacle to nurse-patient communication because a patient may not be able to speak the same language and therefore communication is not possible (Levin,2006). The best way to overcome this barrier is providing a translator who can explain a professional facilitator's message easily to the patient(ibid). For instance, if the nurse only speaks English but the patient is only able to speak Arabic, a translation to the patient of what the professional facilitator is saying leads to less chance of misunderstanding (ibid). Translation also allows a patient to feel comfortable through being able to speak in their own language (ibid).
Medical jargon:
Jargon is a technical language that is comprehended by people in a specific industry or area of work (Leblanc et al.,2014). Health professionals often use jargon to communicate with each other(ibid). For example, T.B. disease stands for tubercle bacillus and HIV stands for human immunodeficiency virus (Mccrary & Christensen,1993). Jargon often makes sense to health professionals but a patient who does not understand these acronyms will not understand such communication, leading to a barrier in therapeutic relationship between patient and health professional (Leblanc et al.,2014).
Communication impairment:
Patients with communication impairment such as blindness, deafness and speech impairment often feel isolated, frustrated and self-conscious (O’Halloran et al.,2009). Some patients are born with such disabilities or have developed them as a result of disease (ibid). Therefore, nurses should provide enough time in order to describe any issue to such patients so that they do not feel uncomfortable or censured by health professionals, who must remain impartial (ibid).
Cultural diversity:
Patients often have various differences (Leblanc et al.,2014).Some of these differences are due to a patient's illness, social status, economic class, education and personality(ibid). However, according to Kirkham (1998), the deepest differences might be cultural diversity. Beheri (2009) points out that many nurses believe if they just treat patients with respect, they will avoid most cultural issues. Nevertheless, avoiding misunderstanding can be achieved through some knowledge of cultural customs, which might help and enable nurses to provide better health care to patients (ibid).
Facilitators of therapeutic relationship:
UNCRPD (2006) states that the most fundamental human right in hospital is communication. Patients are required to be provided with an effective communication method by nurs ...

Critical Analysis of the religious nature of Buddhism
The religious community often debates on whether Buddhism is categorized as a religion or as philosophical teaching. The answer to the question varies depending on an individual’s point of view. There are three main types of Buddhism practices across the world with each of them having smaller branches with slights variances in their teachings and beliefs. The different styles of Buddhist mainly encompass Theravada Buddhism, Vajrayana Buddhism, and Mahayana Buddhism. The various forms often have deities that are worshipped while others do not. Some often have scriptures while others do not usually believe in any physical form of the Buddhist teachings. The first article is authored by Rachel, a blogger, presenting the argument that Buddhism is a religion (Rachel, 1). On the other hand, the second article authored by Pamela Winfield recognizes Buddhism as a philosophy. Analyzing and comparing the two pieces having divergent views on the religious nature of Buddhism is crucial for understanding whether it is a religion or philosophy.
Summary of the articles
Rachel in her article considers Buddhism as a religion. The author acknowledges the fact that Mahayana Buddhism which is often found in greater part of Asia that includes Japan, Korea, and China often teaches on attaining enlightenment (Rachel, 1). The Mahayana often accept that every individual wishes to ensure the effective attainment of enlightenment and thus end the cycle of rebirth which others recognize as “Karma.” The article proceeds to state that Buddha is the greatest of the deities but is not worshipped. Instead, Buddha often inspires all those who practice doing as he once did. The author states that Buddhism often requires that the individuals that choose the wrong path attempt to re-accomplish these tasks in their next life alongside other punishments imposed on them by karma. The characteristics of this type of Buddhism thus often play a significant role in showing the religious nature of Buddhism. The author concludes by stating that Buddhism often contains all the different elements of a religion. Moreover, the article associates Buddhism with fallacies that characterize other religions and just as dangerous as other religions as well. A quote proves the claim on the dangerous nature of Buddhism that the author uses to summarize the teachings of Buddhism.
On the other hand, Winfield tends to focus on enlightening the readers on some of the aspects of Buddhism that ensures its a ...
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel.

Assignment 2 Tests of SignificanceThroughout this assignment yo.docx
1. Assignment 2: Tests of Significance
Throughout this assignment you will review mock studies. You
will needs to follow the directions outlined in the section using
SPSS and decide whether there is significance between the
variables. You will need to list the five steps of hypothesis
testing (as covered in the lesson for Week 6) to see how every
question should be formatted. You will complete all of the
problems. Be sure to cut and past the appropriate test result
boxes from SPSS under each problem and explain what you will
do with your research hypotheses. All calculations should be
coming from your SPSS. You will need to submit the SPSS
output file to get credit for this assignment. This file will save
as a .spv file and will need to be in a single file. In other
words, you are not allowed to submit more than one output file
for this assignment.
The five steps of hypothesis testing when using SPSS are as
follows:
1. State your research hypothesis (H1) and null hypothesis (H0).
2. Identify your confidence interval (.05 or .01)
3. Conduct your analysis using SPSS.
4. Look for the valid score for comparison. This score is
usually under ‘Sig 2-tail’ or ‘Sig. 2’. We will call this “p”.
5. Compare the two and apply the following rule:
a. If “p” is < or = confidence interval, than you reject the null.
Be sure to explain to the reader what this means in regards to
your study. (Ex: will you recommend counseling services?)
2. * Be sure that your answers are clearly distinguishable. Perhaps
you bold your font or use a different color.

We will be using a process for hypothesis testing which outlines
five steps researchers can follow to complete this process:
1. Write your research hypothesis (H1) and your null hypothesis
(H0).
2. Identify and record your confidence interval. These are
usually .05 (95%) or .01 (99%).
3. Complete the test using SPSS.
4. Identify the number under Sig. (2-tail). This will be
represented by "p".
5. Compare the numbers in steps 2 and 4 and apply the
following rule:
1. If p < or = confidence interval, than you reject the null
hypothesis
Determine what to do with your null and explain this to your
reader. Be sure to go beyond the phrase "reject or fail to reject
the null" and explain how that impacts your research and best
describes the relationship between variables.

3. Make up and discuss research examples corresponding to the
various techniques introduced throughout this course. Describe
a plausible study for each of the following statistical
procedures, indicating how it would apply and what results you
would predict. Also include information about the number of
participants you would assess and how you would go about
estimating effect size and statistical power (when relevant). You
will want to address the following: sample, recruitment of
participants, who the sample will represent (ie the population),
what tests will be necessary to explore in a comprehensive way,
and all explanations. You do not need to create actual data, but
will have to justify why you chose which statistical procedures.

1. Researches are interested in whether depressed people
undergoing group therapy will perform a different number of
activities of daily living after group therapy. The researchers
have randomly selected 12 depressed clients to undergo a 6-
week group therapy program.
Use the five steps of hypothesis testing to determine whether
the average number of activities of daily living (shown below)
obtained after therapy is significantly different from a mean
number of activities of 17 that is typical for depressed people.
(Clearly indicate each step).
Test the difference at the .05 level of significance and at the .01
level (in SPSS this means you change the “confidence level”
from 95% to 99%).
As part of Step 5, indicate whether the behavioral scientists
should recommend group therapy for all depressed people based
on evaluation of the null hypothesis at both levels of
significance and calculate the measure of association.

1. Six months after an industrial accident, a researcher has been
asked to compare the job satisfaction of employees who
participated in counseling sessions with the satisfaction of
employees who chose not to participate.
The scores on a job satisfaction inventory for both groups are
listed in the table below.
Use the five steps of hypothesis testing to determine whether
the job satisfaction scores of the group that participated in
counseling are statistically higher than the scores of employees
who did not participate in counseling at the .01 level of
significance.
As part of Step 5, indicate whether the researcher should
recommend counseling as a method to improve job satisfaction
following industrial accidents based on evaluation of the null
hypothesis and calculate the measure of association. NOTE: Do
not forget to give a numeric value for those who participated in
counseling (e.g. 0) and those who did not participate in
counseling (e.g. 1).

ANOVA (20 points)
Open SPSS
Analyze the data for #1. Remember that SPSS assumes that all
the scores in a row are from the same participant. In this study,
there are 15 participants divided into three groups of five.
Therefore, each of the 15 participants will be described by two
variables, type of therapy and the number of activities of daily
living performed.
If “1” represents the group receiving individual therapy for 1
hour every 2 weeks, “2” represents the group receiving 1 hour
of individual therapy each week, and “3” indicates the group
receiving 2 hours of individual therapy each week, the first
participant will be described by entering “1” in the top cell of
the first column in the Data View window and “16” in the top
cell of the second column to indicate that the participant
underwent 1 hour of therapy every 2 weeks and performed 16
activities of daily living. The second participant will be
described by “1” and “15”, and the third by “1” and “18”.
When the two variables have been entered for the five
participants in this group, repeat the process for participants
who underwent 1 hour of individual therapy each week, using
10. “2” to describe their therapy group. When the two variables for
the five participants in this group have been entered, repeat the
process for Group 3, entering “3” in the first column. In the
Variable View window, change the first variable name to
“THERAPY” and the second to “ADL” and set the decimals for
both to zero.
Click Analyze ( Compare Means ( One-Way ANOVA (Since
“THERAPY” is already selected, you can click the arrow to
move the variable to the Factor window. Select “ADL” and
click the arrow to move the variable to the Dependent List
window, which instruct SPSS to conduct the analysis of
variance on the number of activities performed.
Click “Options” and click the box labeled “Descriptive” to
obtain descriptive statistics.
Click Continue.
Click OK.
1. Keep in mind that the clients in Group 1 will receive 1 hour
of therapy every 2 weeks, the clients in Group 2 will receive 1
hour of therapy every week, and the clients in Group 3 will
receive 2 hours of therapy every week.
Use the five steps of hypothesis testing to determine whether
the observed differences in the number of activities in the
following table performed by the three groups are statistically
significant at the .05 level of significance. Clearly indicate each

SPSS instructions:
Chi-Square Test for Goodness of Fit:
Open SPSS
Remember that SPSS assumes that all the scores in a row are
from the same participant. In the study presented in #1, there
are 20 students, some of whom have been suspended for
misbehavior. The primary conflict-resolution style used by each
student is also entered. [Ignore the first variable in this
analysis.]
12. When you have entered the data for all 20 students, move to the
Variable View window and change the first variable name to
“SUSPEND” and the second to “STYLE”. Set the number of
decimals for both variables to zero.
Click Analyze ( Non-Parametric Tests ( Chi-Square
Click the variable “STYLE” and then the arrow next to the box
labeled “Test Variable List” to indicate that the chi-square for
goodness of fit should be conducted on the conflict-resolution
style variable.
Note that “All categories equal” is the default selection in the
“Expected Values” box, which means that SPSS will conduct
the goodness of fit test using equal expected frequencies for
each of the four styles, in other words, SPSS will assume that
the proportions of students each style are equal.
Click OK.
Chi-Square Test for Independence:
Open SPSS
For #2, you need to add the variable “SUSPEND” to the
analysis. Remember that in this problem, we are interested in
whether there was an association between conflict-resolution
style and having been suspended from school for misbehavior.
Since the analysis will involve two nominal variables, the
appropriate test is a chi-square test for independence.
Click Analyze ( Descriptive Statistics ( Crosstabs
Since “SUSPEND” is already selected, click the arrow next to
the box labeled “Rows.”
13. Click the variable “STYLE” and click the arrow next to the box
labeled “Columns.”
Click “Statistics” and click the box labeled “Chi-Square.”
Click Continue.
Click “Cells” and click the box labeled “Expected.”
