Best Answer

You can calculate standard deviation by addin the numbers of data that are together and dividing that number by the amount pieces of data.


What was answered above was the calculation for getting an (mean) average.

If you take five numbers for example 1, 2, 3, 4, 5 then the (mean) average is 3.

But the standard deviation between them is 1.58814 and the variance is 2.5

Also the population std. deviation will be 1.41421 and the population variance will be 2.

Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.

How do you calculate mean and Median smaller then Standard deviation?

In the same way that you calculate mean and median that are greater than the standard deviation!

You cannot because the standard deviation is not related to the median.

How do you calculate standard deviation with the help of z-score?

A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.
