Asample with which of these variances has a standard deviation that is greater than the variance?

a. 2.25
b. 1.75
c. 0.75
d. 1.25

Standard deviation is the square root of the variance. For the square root of a number to be greater than the number, the number must be between 0 and 1.
Hence, for the standard variation to be greater than the variance, the variance must be between 0 and 1.
