3 maj 2024 · You can calculate variance in three steps: Find the difference from the mean for each point. Use the formula: x i − μ x_i - \mu xi −μ. Square the difference from the mean for each point: (x i − μ) 2 (x_i - \mu)^2 (xi −μ)2.
Here’s an example of how to calculate the variance using the sample formula. The dataset has 17 observations in the table below. The numbers in parentheses correspond to table columns. To calculate the statistic, take each data value (1) and subtract the mean (2) to calculate the difference (3), and then square the difference (4).
