DVA DVAR estimates the variance of a sample population, based on the values that meet the specified
The DVAR function provides the variance of a sample population. For this particular function’s
syntax, the database is the cell reference range or named range of the database; and the field is
referenced as the column number from left to right. The criteria is a range that is referenced;
and the function operates from the parameters set. The estimated variance of the sample
database in Figure 3.8 shows the estimated variance in the Western regions. Notice how using the
wildcard symbol allows you to extract variance against all Western regions from West,
Southwest, Midwest, and Northwest. The wildcard symbol extracts all regions in the Western
hemisphere. The result for the year 2000 Western hemisphere is $1,059,002.
