"Variance" and "Standard deviation" are numbers that describe a set of data
that typically contains several numbers. Applied to a single number, neither
of them has any meaning.
-- The variance, standard deviation, and mean squared error of 7 are all zero.
-- The mean, median, mode, average, max, min, RMS, and absolute value of 7 are all 7 .
None of these facts tells you a thing about ' 7 ' that you didn't already know
as soon as you found out that it was ' 7 '.

What is the mean variance and standard deviation for the numbers 2 4 8 2 9 1 7 11 4 7 1 10 1 5?
5.142857143 is the mean.12.43956044 is the variance.3.526976104 is the standard deviation.
Is the variance of a group of scores the same as the squared standard deviation?
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
