σ^{2} = \frac{1}{N} \cdot n \sum i = 1 {(X_{i} - μ)}_{i}^{2}

$sigma^2 = 1/N * sum_(i=1)^n(X_i -mu)^2$

The variance ( $σ$ $sigma$ )of a set of numbers is a measure of how spread out the values are. This equation takes inputs from a column of a table. The table is selectable from enumerated list that is input and takes the values for computing the variance from the table's column named "Values."

This table could be copied and the input table UUID replaced with your own table, thus computing the Population Variance on your table's data. If you want to attach to more than one table, simply add the UUIDs of additional tables that have data in a column labeled "Values."

The table used in this example is "Population Variance Example"
