So, if your sample data is in cells B2 to B14, you will see: =STDEV(B2:B14in the formula bar. Close the bracket for the STDEV formula. So far, you have used the STDEV function to find the Standard deviationof your sample data. Next, we want to divide this Standard deviation by the square rootof the sample size. So let’s continue with our formula..

You can **calculate** the **variance** of a data by taking the differences between each number in the data set and the average, then squaring the differences (which makes them positive), and finally dividing the sum of the squares by the number of values in the data set. The formula is as follows: σ²: **variance**. x: mean (average) of data. . Web. Test for **difference** between two unpaired means with known equal **variance**. The first two are the most common. These tests can be done using descriptive statistics (for two paired means) and regression analysis (for unpaired means with equal **variance**). So no special treatment of **difference** in means is needed..
