Mean 10.70 Standard Deviation 0.030101868

You cannot; there is insufficient information.

Square the standard deviation and you will have the variance.

You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.

Standard deviation = square root of variance.

we calculate standard deviation to find the avg of the difference of all values from mean.,

Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.

Square the standard deviation and you will have the variance.

describe the properties of the standard deviation.

The coefficient of variation is calculated by dividing the standard deviation of a dataset by the mean of the same dataset, and then multiplying the result by 100 to express it as a percentage. It is a measure of relative variability and is used to compare the dispersion of data sets with different units or scales.

No. The expected value is the mean!

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

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