Mean and Standard Deviation Of Raw Data

This is the first of 3 sets of questions on Summary Statistics.

Sheet 1 - raw data

Questions are asked in a helpful manner, though essentially they are all “Find Mean, Variance and Standard Deviation in context” and then interpret your answer.

Answers and a formula sheet are included only in the full set of sheets which we offer at a good price.
