Using the Framingham Data Subset:

Question 01 What inferential test do we use to investigate an association between two categorical variables?

Question 02 Use the test you identified in #1 above to test for independence between GENDER and CHD (use alpha = .05). What are your null and alternative hypotheses? What are your test statistic and corresponding distribution? Write your answer here. What are your degrees of freedom? Calculate your test statistic. Write your answer here. What is your decision? Interpret your findings.

Use the data from question 1. Conduct a hypothesis test at α = .01 to determine if the population variance is greater than 904.75. Question 1: 1. Consider the following sampled data: s 2 = 906.304, n = 31. Calculate the following confidence intervals for the population variance: (a) 90% (b) 95% (c) 99%

What is descriptive statistics? What is inferential statistics? Why do we care about the level of measurement of a variable? Why do we use n-1 rather than n in calculating sample variance? What are confounding variables, and what effect do they have on assessing cause-and-effect relationships? When would you prefer median to mean as a measure of central tendency? Why don’t we just sum the deviations from the mean to measure dispersion of a variable? When is it legitimate to...

Explain why we must verify whether or not the assumptions of an inferential statistical test are met before we calculate the statistic. Specifically, what does a failure to meet the assumptions mean in terms of the α level of our experiment? What should we do if the assumptions are not met?

For what kind of data and analysis do you use a paired t-test and for what kind of data and analysis do you use a non-paired t-test? Be sure to clearly define each of these and illustrate your answer with realistic behavioral examples. The examples used for each must relate to each other, i.e., the one must be a slight modification of the other and use the same organism/system [e.g., if your example for a paired t-test involves elephant breeding,...
