Question

A sample with which of these variances has a standard deviation that is

greater than the variance?
O A. 1.75
O B. 0.25
O C. 2.5
O D. 1.5

Answer 1

0.25

Explanation:

Standard deviation = square root of variance

root 1.75 = 1.3

root 0.25 = 0.5

root 2.5 = 1.5

root 1.5 = 1.22

0.5 > 0.25 therefore the answer is B, 0.25.
