Standard deviation is a number that is equal to the square root of the variance and measures how far data values are from their mean.

The standard deviation and variance both measure the spread of data around the mean. Variance of a data set is the average squared distance between the mean of the data set and each value, whereas the standard deviation is just the average distance between the values in the data set
