Central Tendency and Variability
Discussion: Central Tendency and VariabilityUnderstanding descriptive statistics and their variability is a fundamental aspect of statistical analysis. On their own, descriptive statistics tell us how frequently an observation occurs, what is considered “average”, and how far data in our sample deviate from being “average.” With descriptive statistics, we are able to provide a summary of characteristics from both large and small datasets. In addition to the valuable information they provide on their own, measures of central tendency and variability become important components in many of the statistical tests that we will cover. Therefore, we can think about central tendency and variability as the cornerstone to the quantitative structure we are building.For this Discussion, you will examine central tendency and variability based on two separate variables. You will also explore the implications for positive social change based on the results of the data.To prepare for this Discussion:Review this week’s Learning Resources and the Descriptive Statistics media program.For additional support, review the Skill Builder: Visual Displays for Categorical Variables and the Skill Builder: Visual Displays for Continuous Variables, which you can find by navigating back to your Blackboard Course Home Page. From there, locate the Skill Builder link in the left navigation pane.Review the Chapter 4 of the Wagner text and the examples in the SPSS software related to central tendency and variability.From the General Social Survey dataset found in this week’s Learning Resources, use the SPSS software and choose one continuous and one categorical variable Note: this dataset will be different from your Assignment dataset).As you review, consider the implications for positive social change based on the results of your data.By Day 3Post, present, and report a descriptive analysis for your variables, specifically noting the following:For your continuous variable:Report the mean, median, and mode.What might be the better measure for central tendency? (i.e., mean, median, or mode) and why?Report the standard deviation.How variable are the data?How would you describe this data?What sort of research question would this variable help answer that might inform social change?Post the following information for your categorical variable:A frequency distribution.An appropriate measure of variation.How variable are the data?How would you describe this data?What sort of research question would this variable help answer that might inform social change?Be sure to support your Main Post and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Using the template you have downloaded and the prototype figure below, construct a savings plan spreadsheet using three different methods (iteration (steps), formula, and Excel function) that will arrive at the very same balance if properly done. Be sure to type in the Givens box the same principal, compound, and APR as the prototype figure. From Month #18 (row 26) and thereafter, you will be building formulas that are flexible enough to accommodate other values you type into the Givens box later.

A card is drawn out of a standard deck of 52 cards. Each card can
be described by giving its "rank" (A, 2, 3, 4,...10, J, Q, K) and its
"suit" (H for hearts, C for clubs, D for diamonds, and S for spades).
For example, 2S denotes the two of spades and KH denotes the king of
hearts. Write out the event described by each of the following statements as a set.
E1: "draw a king."E2: "draw a heart."E3: "draw a face card." (A "face" card is a jack, queen, or king.)E4: "draw a joker."
A card is drawn at random out of a well-shuffled deck of 52 cards. Find the probability of each of the following events. (Do problem #2 first.)
E1: "draw a king."E2: "draw a heart."E3: "draw a face card." (A "face" card is a jack, queen, or king.)E4: "draw a joker."
Out of 420 students who took a statistics test, 260 passed. What percentage of the students passed the test? An employee's hourly wage increased from $11.00 per hour to $13.50 per hour. What is the percentage increase in their wage? Suppose that you deposit $3,250.00 in a savings account that pays 0.4% annual simple interest. Assuming no withdrawals are made, find the balance in the account after 6 years. Round your answer to the nearest penny. Suppose that you deposit $3,250.00 in a savings account that pays
0.4% annual interest, with interest credited to the account at the end
of each year. Assuming no withdrawals are made, find the balance in the
account after 6 years. Round your answer to the nearest penny. Suppose $3,250.00 is invested in a savings account with an APR of
0.4% compounded monthly. Assuming no withdrawals are made, find the
balance in the account after 6 years. Round your answer to the nearest
penny. Submit your answers to the questions above by downloading and completing the Probability I Problem Set Worksheet.

GMU Wk4 EB Metabolic Syndrome Prevention & Treatment Program Article Discussion
Implementing an Evidence-Based Metabolic Syndrome Prevention and Treatment Program Utilizing Group VisitsIn this study, the researchers looked at changes in patients understanding of risk factors associated with metabolic disease and changes in habits to decrease those risks. Through a model curriculum, participants were provided information about how their decisions were influencing the development and progression of metabolic disease. .This is an interesting study because here we see the use of both repeated measures t-tests as well as independent t-tests. How did the researchers use both types of t-tests in light of the fact that we discussed you should choose one or the other?Discuss the sample size in the Sumter County sample. Using a a source, discuss the validity of the design with just 5 participants? In the article, the authors indicate that some data are positively-skewed. Discuss the meaning of that, and why would the skew of data interfere with using it in the t-tests? (In your response, consider the distribution of the test statistic). Hospital Rates of People Living with HIV in the United States, 2009 The authors use confidence intervals (CI) throughout their results.Using an example from the article, explain the meaning of the CI for the specific case you selected.How could you decrease the range of a confidence interval?Review Figure 1 carefully. Notice that the CI is given as whiskers on the plot. Using the data in the text about this figure and the overlapping nature of the confidence intervals and the means, explain why there is a significant difference between Black and White but not White and Hispanic.In Table 2 the authors present data surrounding the hospitalization rates based on sex both by OIs (preventable and non-preventable).Research the rate ratio and discuss it for the preventable OIs data.Construct an appropriate graphical representation of the data in Table 2
