To figure the variance on a group of numbers, you must first figure out the mean, which is the average of the set. Then, substract the mean from each number in the set. Square the result of those substractions, and then average the squares. You will then have the variance.

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.
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.
Define error variance-?
The error in which a particular numbers are set apart is called error variance.

What is varience?
In statistics, variance measures how far apart a set of numbers is spread out. If the numbers are identical, the variance is zero. Variance can never be negative.
What is the variance of these set of numbers 11 24 7?
The variance is: 79.0
What is the variance of the numbers 1 7 10 and 3?
The variance of the numbers 1 7 10 and 3 is: 16.25
How do you figure out a mode?
it is the number that appears the most in a group of numbers.

What does variance mean in mathematics?
A variance is a measure of how far a set of numbers is spread out around its mean.
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.
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.
