Question 1047247: True or False. The variance of a data set cannot be negative, but the standard deviation can be negative.
I feel this is true since standard deviation is it measures how far data values are from the mean.

variance = sum of sum of squared deviations/number of data (Always Positive)
Standard Deviation = √Variance
the standard deviation is calculated as the positive square root of the variance (as it represents a distance from the mean)
