IQV Formula

The Index of Qualitative Variation (IQV) is calculated using the following formula:

IQV = [K * (1002 - SUM(Pct^2))] / (1002 * (K - 1))


  • K represents the number of categories or groups.
  • SUM(Pct^2) is the sum of squared percentages for each category.

The IQV formula helps quantify the variation or diversity among categorical data, allowing for insightful comparisons and analysis.
