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.

$Average=\frac{7+9+14+16+22+23}{6}=\frac{91}{6}=15.167$
