Considering the chapters you’ve read, identify the inferential procedure to perform for the following studies: (a) Doing well in statistics should reduce students’ math phobia, so we measure their fear after selecting groups who received a final grade of either an A, B, C, or D. (b) To determine if recall is better or worse than recognition, participants study a list of words, and then half of them recall the words and the other half perform a recognition test. (c) We test the aggressiveness of a group of rats after 1, 3, 5, and 7 weeks to see if they become more aggressive as they grow older. (d) We want to use students’ scores on the first exam in a course to predict their final exam grades. (e) We ask if pilots have quicker reaction times than the copilots they usually fly with.
