Chapter 11: Chi-Square and ANOVA Tests
This chapter presents material on three more hypothesis tests. One is used to determine
significant relationship between two qualitative variables, the second is used to determine
if the sample data has a particular distribution, and the last is used to determine
significant relationships between means of 3 or more samples.
Section 11.1: Chi-Square Test for Independence
Remember, qualitative data is where you collect data on individuals that are categories or
names. Then you would count how many of the individuals had particular qualities. An
example is that there is a theory that there is a relationship between breastfeeding and
autism. To determine if there is a relationship, researchers could collect the time period
that a mother breastfed her child and if that child was diagnosed with autism. Then you
would have a table containing this information. Now you want to know if each cell is
independent of each other cell. Remember, independence says that one event does not
affect another event. Here it means that having autism is independent of being breastfed.
What you really want is to see if they are not independent. In other words, does one
affect the other? If you were to do a hypothesis test, this is your alternative hypothesis
and the null hypothesis is that they are independent. There is a hypothesis test for this
and it is called the Chi-Square Test for Independence. Technically it should be called
the Chi-Square Test for Dependence, but for historical reasons it is known as the test for
independence. Just as with previous hypothesis tests, all the steps are the same except for
the assumptions and the test statistic.
Hypothesis Test for Chi-Square Test
1. State the null and alternative hypotheses and the level of significance
Ho : the two variables are independent (this means that the one variable is not
affected by the other)
HA : the two variables are dependent (this means that the one variable is affected
by the other)
Also, state your α level here.
2. State and check the assumptions for the hypothesis test
a. A random sample is taken.
b. Expected frequencies for each cell are greater than or equal to 5 (The expected
frequencies, E, will be calculated later, and this assumption means E ≥ 5 ).
3. Find the test statistic and p-value
Finding the test statistic involves several steps. First the data is collected and
counted, and then it is organized into a table (in a table each entry is called a cell).
These values are known as the observed frequencies, which the symbol for an
observed frequency is O. Each table is made up of rows and columns. Then each
row is totaled to give a row total and each column is totaled to give a column
total.

The null hypothesis is that the variables are independent. Using the multiplication.

The Chi-Square (x2) Goodness-of-Fit test: What It Is and What It Does
The chi-square (x2) goodness-of-fit test is used for comparing categorical information against what we would expect based on previous knowledge. As such, it tests what are called observed frequencies (the frequency with which participants fall into a category) against expected frequencies (the frequency expected in a category if the sample data represent the population). It is a nondirectional test, meaning that the alternative hypothesis is neither one-tailed nor two-tailed. The alternative hypothesis for a x2 goodness-of-fit test is that the observed data do not fit the expected frequencies for the population, and the null hypothesis is that they do fit the expected frequencies for the population. There is no conventional way to write these hypotheses in symbols, as we have done with the previous statistical tests. To illustrate the x2 goodness-of-fit test, let's look at a situation in which its use would be appropriate.

observed frequencies The frequency with which participants fall into a category.
expected frequencies The frequency expected in a category if the sample data represent the population.
Calculations for the x2 Goodness-of-Fit Test
Suppose that a researcher is interested in determining whether the teenage pregnancy rate at a particular high school is different from the rate statewide. Assume that the rate statewide is 17%. A random sample of 80 female students is selected from the target high school. Seven of the students are either pregnant now or have been pregnant previously. The χ2goodness-of-fit test measures the observed frequencies against the expected frequencies. The observed and expected frequencies are presented in Table 21.1.
TABLE 21.1Observed and expected frequencies for χ2 goodness-of-fit example
FREQUENCIES
PREGNANT
NOT PREGNANT
Observed

As can be seen in the table, the observed frequencies represent the number of high school females in the sample of 80 who were pregnant versus not pregnant. The expected frequencies represent what we would expect based on chance, given what is known about the population. In this case, we would expect 17% of the females to be pregnant .

Description of CHI-SQUARE TEST, Contingency table, Degree of Freedom, Determination of Chi – square test, Assumption for validity of chi - square test, Characteristics , Applications, Limitations
A chi-squared test (χ2) is basically a data analysis on the basis of observations of a random set of variables. Usually, it is a comparison of two statistical data sets. This test was introduced by Karl Pearson in 1900 for categorical data analysis and distribution. So, it was mentioned as Pearson’s chi-squared test.
In general, a factorial experiment involves several variables.
One variable is the response variable, which is sometimes called the outcome variable or the dependent variable.
The other variables are called factors.

CompetencyAnalyze ethical and legal dilemmas that healthcare.docxbartholomeocoombs
Competency
Analyze ethical and legal dilemmas that healthcare workers may encounter in the medical field.
Instructions
You have recently been promoted to Health Services Manager at Three Mountains Regional Hospital, a small hospital located in a mid-size city in the Midwest. Three Mountains is a general medical and surgical facility with 400 beds. Last year there were approximately 62,000 emergency visits and 15,000 admissions. More than 6,000 outpatient and 10,000 inpatient surgeries were performed.
An important aspect of the provider/patient relationship pertains to open communication and trust. Patients want to know that their doctors and the support staff associated with their care understand their wishes and will abide by them. Ideally, these conversations happen well before an emergency or procedure takes place; however, often times this information is missing from a patient's file. As part of Three Mountains' initiative to build trust with their patients, an increased emphasis has been placed on obtaining living wills from the patient as part of the intake process to ensure that the healthcare team has written directives of the patient's wishes in case of incapacitation. You will be creating a living will for a patient and provide educational information as to why the patient should fill it out during the admission process before a procedure.
Introduction:
Explain the definition of a living will and its key components. This section will provide an educational overview of the document for the patient.
Living Will Template:
Create a living will that can serve as a template to the patients. This should cover the basic treatment issues such as resuscitation, feeding tubes, ventilation, organ and tissue donations, etc. Provide instructions in the template that can be easily altered, depending on each patient's wishes.
Summary:
In this section, you will discuss the importance of this document and encourage patients to complete it. Address how this document ensures that a patient's wishes are known and followed by the healthcare team.

Recent Developments in Lifelong Learning
Karl Steffens
Introduction
We think of our societies as ‘knowledge societies’ in which lifelong learning is
becoming increasingly important. Lifelong learning refers to the idea that people
not only learn in schools and universities, but also in non-formal and informal
ways during their lifespan.The concepts of lifelong learning and lifelong education
began to enter the discourse on educational policies in the late 1960s (Tuijnman
& Boström, 2002). However, these are related, but distinct concepts. As Lee (2014,
p. 472) notes ‘the terminological change (from lifelong education, continuing
education and adult education, to lifelong learning) reflects a conceptual departure
from the idea of organised educational provision to that of a more individualised
pursuit of learning’.
One of the first important documents on lifelong learning was the report of the
International Commission on the Development of Education to UNESCO in
1972, titled ‘Learning to be. The world of education today and tomorrow’. In his
introductory letter to the Director-General of UNESCO, the chairman of the
Commission, Edgar Faure, stated that the work of the Commission was based on
four assumptions (see Elfert pp. and Carneiro pp. in this issue). The first was
related to the idea that there was an international community which was united by
common aspirations and the second was the belief in democracy and in education
as its keystones. The third was ‘that the aim of development is the complete
fulfilment of man, in all the richness of his personality, the complexity of his forms
of expression and his various commitments — as individual, member of a family
and of a community, citizen and producer, inventor of techniques and creative
dreamer’. The last assumption was that ‘only an over-all, lifelong education can
produce the kind of complete man, the need for whom is increasing with the
continually more stringent constraints tearing the individual asunder’ (Faure,
1972, p. vi).
Following the Faure Report, the UNESCO Institute for Education, which
was founded in Germany in 1951, started to focus on lifelong learning and
subsequently became the UNESCO Institute for Lifelong Learning (UIL, http://
uil.unesco.org/home/). It was under its leadership that a formal model of lifelong
education was developed and published in the book ‘Towards a System of Life-
long Education’ (Cropley, 1980). The concept of lifelong learning also became
manifest in the ‘Education for All’ (EFA) agenda that was launched at the World
Conference on Education for All which took place in Jomtien (Thailand) in
1990 (Inter-Agency Commission, 1990). Ten years later, at the World Education
Forum in Dakar (Senegal) in 2000, the Dakar Framework for Action was
designed ‘to enable all individuals to realize their right to learn and to fulfil their
responsibility to contribute to the development of their society’ (UNESCO,
2000, p..

Introduction
Base Salary Range
For the position of VP of Operations, the National Average Salary is $122,624. In San Francisco, the average is higher and placed at $155,946. This amount is 16% higher than the National Average (Payscale, 2016). The reason for this increase is because of experience and geography. These are the two prime factors that impact the pay scale. Another major factor is the employer. Most employers base their decision to hire an individual on the experience they bring with them. Of course, with more experience, higher pay is required. With our company cutting cost a less experienced individual would be the best fit for the position.
Standard Employee Benefit
In many cases, your employee benefits could be the turning point for a prospective employee. This benefit is a vital portion of any employee packet. These valuable benefits are used as a blanket of security in the case of any sickness, injury, unemployment, old age, or death (Gomez-Mejia, Balkin & Cardy, 2015, p. 362). There is a significant difference between incentives and benefits: benefits are financial and nonfinancial compensations that are indirect to the employee. To have a competitive strategy Blossoms Up! must align their profits with the compensation package that has been already put in place. This action will help provide flexibility to the amount and the benefits available (Gomez-Mejia et al., 2015).
There are also some benefits that most companies are legally obligated to provide. Three benefits are required regardless of the number of employees that the company has. These interests involve social security, workers compensation, and unemployment insurance (Gomez-Mejia et al., 2015). Other laws must be adhered to when dealing with a certain number of individuals. When a company has 50 or more employee they must have the Family and Medical Leave Act in place and since its induction in 2015 the Affordable Care Act for Health Insurance for companies with 20 or more employees. For the health insurance to be considered standard medical, vision and dental plans must be made available to the business. These programs that must be regarded as being under the Health Maintenance Organization (HMO) or a Preferred Provider Organization (PPO) (Gomez-Mejia et al., 2015).
There are some voluntary benefits that we can include. We are already looking into adding a pension package using the Defined Contribution Plan as well as the 401(K) plan (Gomez-Mejia et al., 2015). Life insurance is another excellent benefit that could be added to the package as well as short-term and long-term disability insurance. Adding Vacation and PTO, and Holiday pay is .

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Chapter 11: Chi-Square and ANOVA Tests
This chapter presents material on three more hypothesis tests.
One is used to determine
significant relationship between two qualitative variables, the
second is used to determine
if the sample data has a particular distribution, and the last is
used to determine
significant relationships between means of 3 or more samples.
Section 11.1: Chi-Square Test for Independence
Remember, qualitative data is where you collect data on
individuals that are categories or
names. Then you would count how many of the individuals had
particular qualities. An
example is that there is a theory that there is a relationship
between breastfeeding and
autism. To determine if there is a relationship, researchers
could collect the time period
that a mother breastfed her child and if that child was diagnosed
with autism. Then you
would have a table containing this information. Now you want
to know if each cell is
independent of each other cell. Remember, independence says
that one event does not
affect another event. Here it means that having autism is
independent of being breastfed.
2. What you really want is to see if they are not independent. In
other words, does one
affect the other? If you were to do a hypothesis test, this is
your alternative hypothesis
and the null hypothesis is that they are independent. There is a
hypothesis test for this
and it is called the Chi-Square Test for Independence.
Technically it should be called
the Chi-Square Test for Dependence, but for historical reasons
it is known as the test for
independence. Just as with previous hypothesis tests, all the
steps are the same except for
the assumptions and the test statistic.
Hypothesis Test for Chi-Square Test
1. State the null and alternative hypotheses and the level of
significance
Ho : the two variables are independent (this means that the one
variable is not
affected by the other)
HA : the two variables are dependent (this means that the one
variable is affected
by the other)
Also, state your α level here.
2. State and check the assumptions for the hypothesis test
a. A random sample is taken.
b. Expected frequencies for each cell are greater than or equal
to 5 (The expected
frequencies, E, will be calculated later, and this assumption
means E ≥ 5 ).
3. 3. Find the test statistic and p-value
Finding the test statistic involves several steps. First the data is
collected and
counted, and then it is organized into a table (in a table each
entry is called a cell).
These values are known as the observed frequencies, which the
symbol for an
observed frequency is O. Each table is made up of rows and
columns. Then each
row is totaled to give a row total and each column is totaled to
give a column
total.
Chapter 11: Chi-Squared Tests and ANOVA
360
The null hypothesis is that the variables are independent. Using
the multiplication
rule for independent events you can calculate the probability of
being one value of
the first variable, A, and one value of the second variable, B
(the probability of a
particular cell P A and B( ) ). Remember in a hypothesis test,
you assume that H0
is true, the two variables are assumed to be independent.
P A and B( ) = P A( ) ⋅ P B( ) if A and B are independent
= number of ways A can happen
4. total number of individuals
⋅ number of ways B can happen
total number of individuals
= row total
n
*
column total
n
Now you want to find out how many individuals you expect to
be in a certain cell.
To find the expected frequencies, you just need to multiply the
probability of that
cell times the total number of individuals. Do not round the
expected frequencies.
Expected frequency cell A and B( ) = E A and B( )
= n row total
n
⋅ column total
n
⎛
⎝⎜
⎞
⎠⎟
5. = row total ⋅ column total
n
If the variables are independent the expected frequencies and
the observed
frequencies should be the same. The test statistic here will
involve looking at the
difference between the expected frequency and the observed
frequency for each
cell. Then you want to find the “total difference” of all of these
differences. The
larger the total, the smaller the chances that you could find that
test statistic given
that the assumption of independence is true. That means that
the assumption of
independence is not true. How do you find the test statistic?
First find the
differences between the observed and expected frequencies.
Because some of
these differences will be positive and some will be negative,
you need to square
these differences. These squares could be large just because the
frequencies are
large, you need to divide by the expected frequencies to scale
them. Then finally
add up all of these fractional values. This is the test statistic.
Test Statistic:
The symbol for Chi-Square is χ

O − E( )2

where O is the observed frequency and E is the expected
frequency
Chapter 11: Chi-Square Tests and ANOVA

Distribution of Chi-Square
χ
2 has different curves depending on the degrees of freedom. It
is skewed to the
right for small degrees of freedom and gets more symmetric as
the degrees of
freedom increases (see figure #11.1.1). Since the test statistic
involves squaring
the differences, the test statistics are all positive. A chi-
squared test for
independence is always right tailed.

7. p-value:
Use χcdf lower limit,1E99, df( )
Where the degrees of freedom is df = # of rows−1( )* # of
columns−1( )
4. Conclusion
This is where you write reject Ho or fail to reject Ho . The
rule is: if the p-value
< α , then reject Ho . If the p-value ≥α , then fail to reject Ho
5. Interpretation
This is where you interpret in real world terms the conclusion to
the test. The
conclusion for a hypothesis test is that you either have enough
evidence to show
HA is true, or you do not have enough evidence to show HA is
true.
Example #11.1.1: Hypothesis Test with Chi-Square Test Using
Formula
Is there a relationship between autism and breastfeeding? To
determine if there
is, a researcher asked mothers of autistic and non-autistic
children to say what
time period they breastfed their children. The data is in table
#11.1.1 (Schultz,
Klonoff-Cohen, Wingard, Askhoomoff, Macera, Ji & Bacher,
2006). Do the data

autism are
independent? Test at the1% level.

b. Expected frequencies for each cell are greater than or equal
to 5 (ie. E ≥ 5 ).
10. See step 3. All expected frequencies are more than 5.
3. Find the test statistic and p-value
Test statistic:
First find the expected frequencies for each cell.

5. Interpretation
There is not enough evidence to show that breastfeeding and
autism are
dependent. This means that you cannot say that the whether a
child is breastfed or
not will indicate if that the child will be diagnosed with autism.
