If the standard deviation of a data is 3.6 and each value of the data is divided by 3, then find the new variance and new standard deviation.

If the standard deviation of a data is 4.5 and if each value of the data is decreased by 5, then find the new standard deviation.

Find the standard deviation for the data :

The standard deviation of a data is 5. If each value is multiplied by 2, then the new variance is

The standard deviation of a data is 3 . If each value is multiplled by 5 then the new variance is

The standard deviation of 50 values of a variable x is 15, if each value of the variable is divided by (-3) , then the standard deviation of the new set of 50 values of x will be

The standard deviation of the following data is

The standard deviation of a collection data is 5sqrt(5) .If each value is multiplied by 3 then the new variance of the new data is ………….

The standard deviation of 15 items is 6 and each item is decreased by 1. Then find the standard deviation of new data.
