relationship between dispersion and central tendency Solution Central tendency refers to and locates the center of the distribution of values. Mean, mode, and median are the most commonly used indices in describing the central tendency of a data set. If a data set is symmetric, then both the median and the mean of the data set coincide with each other. Dispersion is the amount of spread of data about the center of the distribution. Range and standard deviation are the most commonly used measures of dispersion. Two kinds of statistics are frequently used to describe data. They are measures of central tendency and dispersion. These are often called descriptive statistics because they can help you describe your data. THE RELATIONSHIP BETWEEN DISPERSION AND CENTRAL TENDENCY IS THAT ARE DESCRIPTIVE STATISTICS THAT CAN HELP YOU TO DESCRIBE THE DATA THAT YOU ARE INVESTIGATING.

ANALYSIS AND INTERPRETATION OF DATA Analysis and Interpretation of Data https://my.visme.co/render/1454658672/www.erau.edu Slide 1 Transcript In a qualitative design, the information gathered and studied often is nominal or narrative in form. Finding trends, patterns, and relationships is discovered inductively and upon reflection. Some describe this as an intuitive process. In Module 4, qualitative research designs were explained along with the process of how information gained shape the inquiry as it progresses. For the most part, qualitative designs do not use numerical data, unless a mixed approach is adopted. So, in this module the focus is on how numerical data collected in either a qualitative mixed design or a quantitative research design are evaluated. In quantitative studies, typically there is a hypothesis or particular research question. Measures used to assess the value of the hypothesis involve numerical data, usually organized in sets and analyzed using various statistical approaches. Which statistical applications are appropriate for the data of interest will be the focus for this module. Data and Statistics Match the data with an appropriate statistic Approaches based on data characteristics Collected for single or multiple groups Involve continuous or discrete variables Data are nominal, ordinal, interval, or ratio Normal or non-normal distribution Statistics serve two functions Descriptive: Describe what data look like Inferential: Use samples to estimate population characteristics Slide 3 Transcript There are, of course, far too many statistical concepts to consider than time allows for us here. So, we will limit ourselves to just a few basic ones and a brief overview of the more common applications in use. It is vitally important to select the proper statistical tool for analysis, otherwise, interpretation of the data is incomplete or inaccurate. Since different statistics are suitable for different kinds of data, we can begin sorting out which approach to use by considering four characteristics: 1. Have data been collected for a single group or multiple groups 2. Do the data involve continuous or discrete variables 3. Are the data nominal, ordinal, interval, or ratio, and 4. Do the data represent a normal or non-normal distribution. We will address each of these approaches in the slides that follow. Statistics can serve two main functions – one is to describe what the data look like, which is called descriptive statistics. The other is known as inferential statistics which typically uses a small sample to estimate characteristics of the larger population. Let’s begin with descriptive statistics and the measures of central tendency. Descriptive Statistics and Central Measures Descriptive statistics organize and present data Mode The number occurring most frequently; nominal data Quickest or rough estimate Most typical value Measures of central tendenc.

A. The statement \"Evolutionists cannot point to any transitional fossils\" is very frustrating to the scientific community. Answer the following questions. 1. What does a creationist mean by transitional form vs. what a scientist means by transitional form? 2. What is the frustration issue? B. You are an evolutionary biologist in a heated argument with a creation scientist who makes the statement—\"Mathematically, it is inconceivable that anything as complex as a protein, let alone a living cell or a human, could spring up by chance\". 1. Make a supporting statement for chance. 2. Now play the other side and respond to the supporting statement as you think a creation scientist would respond.? Solution The creationists do not believe in evolution, they believe that god created the earth and he only destroys it . they believe in the theory of intelligent design, therefore: answer A: 1: creationist mean that the transitional forms are a result of intelligent design by god and are not due to natural selection or evolution, whereas, scientists believe that transitional forms are a product of natural selection and they are like missing links that fill in the gaps between two phylums. As one phylum progresses to evolve in another phylum, some of the characters of advanced phylum remain in the animals giving rise to the transitional forms like the archeopteryx. 2. The frustration issue might be that there is a proof that such transitional forms existed and were very rare, they have been found in the fossilized form worldwide and yet the creationists continue to say that any such forms or organisms don\'t exist..

Culture of bacteria is having trouble dividing. Choose from the list of genes to show which of them might have a mutation responsible for the following malfunctions. Choose the best gene for each malfunction. All will not be used. ftsZ minC zipA xerD DNA pol III dnaA TOPOIV Malfunction 1-Two daughter cells result, but one has two copies of the chromosome concatenated into a big circle. Malfunction 2-Replication never starts. Malfunction 3-Cell divides at the poles Malfunction 4-DNA replication has slowed such that it is not finished with the whole genome by the time cell is trying to septate. Solution Malfunction 1-Two daughter cells result, but one has two copies of the chromosome concatenated into a big circle. -TOPO IV Introduces single-stranded break into concatenated chromosomes to release them from each other. And if it is mutated then concatenated chromosomes are not separated and may be one cell has two copies of chromosome into big circle. Malfunction 2-Replication never starts. -DnaA is a protein that activates initiation of DNA replication in bacteria. So if this protein is mutated then replication is not initiated I.e. never starts. Malfunction 3-Cell divides at the poles. -MinC is known to dimerize and functions as an FtsZ protein inhibitor(It forms a ring at the site of constriction). And if MinC is mutated then cell divides at poles. Malfunction 4-DNA replication has slowed such that it is not finished with the whole genome by the time cell is trying to septate. -DNA pol III is the main enzyme that adds nucleotides in the 5 to 3 direction I.e It helps in strand elongation. But this is mutated then DNA replication is not appropriate..

You identify four mutant strains that cannot synthesize Compound E. Each strain contains a single mutation. You test the ability of each of these mutants to grow when a specific compound (known to be an intermediate in the synthesis of Compound E) is added to the minimal growth medium. In the table below, the ability to grow is represented by \"+\" and the inability to grow is represented by \"-\". Propose a biosynthetic pathway for the synthesis of Compound E. Compounds that are added to the growth media a. Draw the biosynthetic pathway for Compound E, indicating the order in which the intermediates are generated and which step is affected by each mutant. b. You isolate a fifth mutant and show that it complements all five of the mutants described above. When tested for growth on compounds A-E, it shows a pattern identical to mutant 2. How could you explain this result? Solution Answer: The biosynthetic pathway for compound E starts with compound A. Compound A produce compound D. From compound D, compound C is obtained and compound D is the immediate precursor for compound E. In the second part of the question a fifth mutant has been introduced.

Identify the species/population and tell us which factors and why those factors affect stochasticity. 9. Identify at least two factors that influence the degree of stochasticity in birth and death rates for a species/population of your choosing. Identify the species/population and tell us which factors and why those factors affect stochasticity. Solution Environmental fluctuations: a major factor that influences the degree of stochasticity in birth and death rates for a species, result in changes in high to low birth & death rates that cause higher alteration in stages of demographic transition. For example, a majority of bird species & butterflies have undergone extinction due to \"industrial revolution followed by the degree of stochasticity in birth and death rates of species\" finally triggered environmental fluctuation Inbreeding depression: this is leading to low fitness finally trigger that influence the degree of stochasticity in birth and death rates for a species/population. Inbreeding results in decreased heterozygous alleles and increase in homozygous alleles. This results in increased chances of inheriting the deleterious alleles or the recessive alleles, which would cause increase in genetic disorders and decrease in allelic diversity finally low level of birth rate to death rate Immigration/emmigration events: the total population changes with immigration & emigration events in a particular area or country based on pre-industrial, environmental, natality & moratility rates and the population growth (influence the degree of stochasticity in birth and death rates) and reduction are both explained in 5 stages of model. The major comparison of stage II is to a country in stage IV, “growth rate is higher in stage II due to higher sanitation and higher food supply as a result higher life expectancy & low infant mortality compared to the growth rate and fertility rate observed in stage IV. Stage IV is composed of population with life expectancy is lower compared to stage II as a result both birth rate & death rate are lower. This is leading to proportion of the population less than 15 years of age in stage IV (low demographic transition) with low economy compared to stage II finally result in low fertility of population with inadequate food sources in the population..

What are the fuctional need of a road? What is road building system? Solution Prob. 1 Different classes of roads are constructed with different geometric design and to meet the different funcitonal needs. 1. The Arterial Interstate roads/highways are constructed to interconnect states of a country with high mobility and access to major cities. 2. Expressways are contructed to provide a function of very hight mobility in a particular direction or connected some major cities of a country so as to reduce the time of travel. There access and egress points are limited and therefore the traffic is to and fro from the major end points only. 3. Similar to major arterial roads, there are minor arterial roads which serve the smaller areas and lengths. In urban areas their function is to connect major metropolitan cities, while in rural parts, they connect major cities and towns. 4. The collector roads are constructed to function as the feeder roads for the arterial roads. They collect the traffic from the local roads and lead them to the arterial roads. There lengths and amount of traffic puts them into one of the two categories of major or minor collector roads. 5. Then there are the local roads constructed to cater the transportation needs in different localities. There lengths are limited to their respective locality but if we calculate the total lengths of the local roads in a country, they form the largest road network by mileage..

Why does Germany have to be assertive in the EU? Solution Answer Germany\'s talk of a new, more assertive foreign policy that relies more heavily on its military is, however, not solely linked to concerns over Russia or the United States. Germany has accepted that its only option is to rally Europe but as the past six years have shown, it has had limited success on the economic front. The European Union is an economic entity, but economics has turned from being the binding element to being a centrifugal force. Either something new must be introduced into the European experiment, or it might come undone. Berlin believes that holding the European Union together requires adding another dimension that it heretofore has withheld in its dealing with the bloc: military-political relations. Standing up to a weakening Russia will appeal to Central European nations, and taking a more active role overseas would endear Berlin to Paris. Germany\'s allusions that it would expand its international military operations, particularly in Africa, is a clear nod to France, which has consistently expressed its desire for a deeper military and political partnership with Germany. Notably, the drive to bring Germany closer to France in the short term could create tensions between them in the long term. Last week\'s summit between British Prime Minister David Cameron and French President Francois Hollande was a reminder that France and the United Kingdom may have extremely different views regarding the European Union but still see each other as a military partner and, more important, as a counterweight to Germany. Of course, Germany is in no position to take military action. It is in a position to posit the possibility in some vague way, thereby generating political forces that can temporarily hold things together. Berlin needs to buy time, particularly in Central Europe, where Hungary has embarked on an independent course and is being watched carefully by others. With the United States unwilling to become involved, Germany either becomes the counterweight or lives with the consequences. At first, Germany\'s actions seemed confusing and uncharacteristic. But they become more sensible when you consider that that Berlin is looking for other tools to hold the European Union together as it re-evaluates Russia. So far, Germany\'s announcement has been met positively, mainly outside Germany, but the tensions that a stronger and more assertive Berlin exerts on the European continent and the global stage are sure to come to the fore again. For now, however, Merkel has no choice..

What is the link between wealth and welfare? Do governments have a responsibility to address welfare? Solution Wealth refers to the monetary value of net assets and income earned and accumulated by an economic entity. Welfare relates to the increase in overall standard of living, including non- monetary standards. In general it is presumed that higher wealth leads to higher welfare. However, that holds true only an an individual level - individuals raise their standard of living and higher welfare state, as they gather more wealth. But at an aggregative level, an overall nation\'s wealth doesn\'t define its welfare state. That is why, the welfare programs are mostly undertaken by the government to ensure that the standard of living and overall welfare be raised for those sections of the society who cannot afford it. Governments spend a considerable portion of their GDP every year for welfare programs..

Where does mitosis occur in the bodies of vascular plants? Solution Ans. The following cells/ tissue in the vascular plants show mitotic events- I. Meristem tissues: Apical meristems (primary meristem) of shoot and root is under constant mitotic divisions. Mitosis in these regions is the primary factor responsible for primary growth (longitudinal, increase in height). Secondary meristems divide mitotically and responsible for lateral growth (increase in thickness). II. Parenchyma cell (ex- xylem and phloem parenchyma) constituting the parenchymatous tissue show totipotency i.e. under appropriate conditions, these calls can dedifferentiate into embryonic cells and form the entire plant through mitoses. These cells also may also divide to form new cells meant for tissue repair..

What was Kant\'s ideas regarding retributive punishment? Solution Kant idea of redistributive justice: \"Judicial punishment can never be used merely as a means to promote some other good for the criminal himself or for civil society, but instead it must in all cases be imposed on him only on the ground that he has committed a crime.\" Kant regards punishment as a matter of justice, and it must be carried out by the state for the sake of the law, not for the sake of the criminal or the victim. He argues that if the guilty are not punished, justice is not done. Further, if justice is not done, then the idea of law itself is undermined..

Clearly these differences may be difficult for the prokaryotes in the jury to follow unless you how the similarities and differences. Solution Answer: 1. Stages of Mitosis: a. Interphase: Cell grows and makes a copy of DNA. b. Prophase: Nuclear envelope breakdown, chromosomes condenses and spindle formation takes place. c. Metaphase: Chromosomes are lined up precisely on the metaphase plate, or middle of the cell. d. Anaphase: Spindle pulls sister chromatids apart. e. Telophase: Chromatids begin to decondense and become chromatin. Spindle disappears. f. Cytokinesis: Divide cell and organelles. Actin ring, or cleavage furrow splits cell. 2. Prokaryotic cells Binary fission: Prokaryotic cells are simple in structure when compared to eukaryotic cells. They contain non- membranous organelles, lack a cell nucleus, and have a simplistic genome: only one circular chromosome of limited size. Therefore, prokaryotic cell division, a process known as binary fission, is fast. The chromosome is duplicated prior to division. The two copies of the chromosome attach to opposing sides of the cellular membrane. Cytokinesis, the physical separation of the cell Eukaryotic cells Mitosis: The division of the nucleus, separating the duplicated genome into two sets identical to the parent\'s. Cytokinesis: The division of the cytoplasm, separating the organelles and other cellular components. Meiosis: The division of the nucleus in sex cells, making one cell into four sex cells identical to the parent sex cell. Eukaryotic cells divide by separating the duplicated chromosomes, through movements directed by microtubles. it protect the organ system of our body. Degradation: Multicellular organisms replace worn-out cells through cell division. In some animals, however, cell division eventually halts. In humans this occurs on average, after 52 divisions, known as the Hayflick limit. The cell is then referred to as senescent. Senescent cells deteriorate and die, causing the body to age. Cells stop dividing because the telomeres, protective bits of DNA on the end of a chromosome, become shorter with each division and eventually can no longer protect the chromosome. Cancer cells, on the other hand, are \"immortal.\" An enzyme called telomerase, present in large quantites in cancerous cells, rebuilds the telomeres, allowing division to continue indefinitely. Daughter chromosomes : During the metaphase stage of mitosis, chromosomes, which become aligned on the equatorial plane, take on the shape of an \"X\" as a result of a repelling force between chromosomes. The lobes of the chromosome in this shape are called \'sister ch.

What challenges do corporations face with regards to social media? Solution Answer: With the advent of internet , social media turned the life into new stage. Before internet , childrens were busy in playing toys. But today\'s generation busy in playing vedio games online on the computer. All round change is there. Wherever we look , all are busy on their tabs , laptops and mobile phones : chating , vedio calling and making VoIP calls . Social media is good to bring people together , keep friends in touch all the time. But excess of everything is bad. Students in colleges and universities , employees in the companies pay more attention on chating and vedio calling rather than what actually they came for. According to a research conducted recently Proofpoint found that 8 % companies had terminated employees because of social media usage. As the employees sharing their sensitive information in the social media that could be vulnerable to the whole database of the company. Here are few challenges that every should plan : 1. Integration 2. Governance 3. Culture 4. Human Resources 5. Cyber Bullying Crisis 6. Personal opinions.

There are no organs for excretion and gas exchange in cnidarians. How do they accomplish these two functions? Solution Humans have lungs which is well developed to breath in and expel out the gases. In fishes, the gills plays role in respiration. In certain organisms like frogs even skin also act in passive exchange of gases. Cnidarians like in water but they do not have any gills to respire. They are not well developed to possess lungs. Diffusion is the process which could be seen in exchange of gases in cnidarians. The gaseous particles move from higher concentration to lower concentration through direct diffusion in cnidarians. Cnidarians lack digestive, excretory and circulatory systems. Gastrovascular cavity plays main role in digestion and distribution of food particles throughout the body in cnidarians and also in expelling waste materials to out through its single opening. This gastrovascular cavity has a single opening which both acts as mouth and anus. This gastrovascular cavity functions in respiration, digestion, and discharge of gametes. All the food particles/waste particles enter and exit the gastrovascular cavity through its single opening. Nitrogenous waste materials have been removed in the form of ammonia have been excreted through body surfaces..
