2 of 4 1.2 Case Study Review: resistance to outliers Question 1 . Make a table listing the measures of center (mean, median, mode, midrange) and variation (range, IQR, standard deviation) we have discussed in terms of their resistance to outliers. Demo Validate the Empirical Rule using percentiles and 100 randomly generated data points for a normal distribution. Show how the empirical rule fails with a uniform distribution. (Time permitting.) 1.2 Case Study Research Question Are male and female students at this institution the same height on average? Question 2 . What is the population of interest? Question 3 . If a census is not possible, what method of sampling would be appropriate. To answer this question we will sample the heights of students in this class. Question 4 . What type of sample is this? Collected Data R: load ( ”ClassData . RData”) R: height . male = c l a s s . data $ height [ c l a s s . data $ gender == + ”MALE” ] R: height . female = c l a s s . data $ height [ c l a s s . data $ gender == + ”FEMALE” ] R: height . male [ 1 ] 71 77 70 67 73 68 70 R: height . female
