-Calculate SS, variance, and standard deviation for the following sample of n = 6 scores: 11, 0, 8, 2, 4, 5. (The definitional formula works well with these scores).
-Calculate SS, variance, and standard deviation for the following sample of n = 4 scores: 4, 0, 1, 1. (The computational formula works well with these scores).
-A recent study reports that older adults who got regular physical exercise experienced fewer symptoms of depression, even when tested 2 years later. Following are hypothetical data similar to the results from the study.
a. What is the mean and standard deviation for each group of scores? b. Based on the statistics from part a (Hint: the mean), does there appear to be a difference between the two groups?
Regular Exercise : 1, 3, 4, 3, 5, 2, 3, 4
No Regular Exercise: 5, 4, 6, 3, 5, 7, 6, 6
