The this is the simplest relationship between variance and standard deviation, This represents the need to understand how these two calculations work to provide insight into the various aspects of the data you are studying. Additionally, standard deviation represents the relative range of a data set and does not account for outliers in either direction of the standard mean. Variance, on the other hand, represents all variable changes or differences in a data set, including relative outliers on either side of the mean. Without these two statistical factors, there would be no diversity in the data range of the sample set.
Meaning the values ββin the data set will cluster more around the mean than spread out, similar to a bell curve.

You can also calculate just a sample of all data points.
In the example of a simple annual sales report, the sample could be summer sales totals. In this case, the statistician will measure a set of samples within a certain date range. In both of these examples, you can calculate the variance using one of the two variance formulas below: Calculating the Variance of an Entire Data Set If you are measuring the entire data set, use the following steps for the variance formula for the entire data set: Variance = (Sum of each term β average. Subtract the average from each value in your data set. Your first step is to subtract your population mean from each term in your set.
