In the Market Ranking report, there is an option to include an Average Rank field in your output. This is a helpful feature to show an overall ranking of all variables when more than one ranking field is important to your decision making. For example, you may rank the top twenty counties by greatest Per Capita Income but want to see how the ranks are affected when Total Population, Average Family Size, and Total Housing Units are included for each geography.
In the example below, the Average Rank field calculation methodology is described using a group of ZIP Code boundaries containing three demographic variables, plus the area field. So there are four total variables tied to five boundaries used in the ranking.
Because the ranking is an average of all other variable ranks combined, the Average Rank field does not produce simple 1, 2, 3, 4, and so forth, rank output.
