Although it is possible to plug these numbers into the calculator and obtain the exact value of the standard deviation, this will take quite a lot of time to accomplish.

Standard deviation is a measure of spread. The numbers in data set A deviate from the group because there are a lot of large and small values relative to the mean.

The values in data set B in comparison are closer to the mean of the data set. Relatively, the standard deviation of set B is lower than the standard deviation of set A.
