The variance of a data set with 10 numbers is 12 . what is the standard deviation ? a. 1.2 b. 3.46 c. 6 d. 144

Std. dev. = 3.46

Explanation:

The standard deviation is the square root of the variance.

Given that, Varience of 10 numbers = 12

S.D = √V

Where,

S.D = Standard Deviation

V = variance

S.D = √12

S.D = 3.46

Both standard deviation and variance are derived from the mean of a given data set. If the mean is simply the average of all data points, the variance measures the average degree to which each point differs from the mean.
