Question

Find the range, standard deviation and the variance of 7,9,14,16,22,23

Answer 1

Given

7,9,14,16,22,23

Range = Maximum score - minimum score

Range= 23-7=16

Standard deviation is defined as the average amount a number differs from the mean.

`Average=(7+9+14+16+22+23)/(6)=(91)/(6)=15.167`
