Question

The table shows the test scores of students who studied for a teat as a group (group a) and students who studied individually (group b).

Which would be the best measures of center and variation to use to compare the data?

Answer 1

Answer: B

Explanation:

I didn't waste time looking at if the data was Symmetric or skewed, because A, C and D are all false statements:

A - If it's skewed Mean wouldn't be used

C - If it's Symmetric IQR wouldn't be used

D - If it's skewed Standard Deviation wouldn't be used
