An iqv of .35, which describes the level of racial diversity in a southern u.s. state, can be interpreted as 'the southern state of interest sees 35% of the maximum possible differences'.
The index of qualitative variation (IQV) is a measure of the variability of nominal variables such as race, ethnicity, and gender. This type of variable classifies people into categories that cannot be ranked, as opposed to being able to measure income and education that changes from high to low. The index of qualitative variation can vary from 0.00 to 1.00. If we want to look at the changing racial diversity of a place over period of time, we can use the IQV to see how diversity has evolved.

It is not reasonable to say there is a correlation because it is categorical data. However if it was quantitative data, correlation doesn’t always mean causation, because there might be athird variable (lurking variable) that may have a better explanation for the correlation.
Explanation:
Is it not reasonable to say that there's a correlation between the type of car you own and the risk that it will be stolen because it is categorical data. However if it was quantitative data, correlation doesn’t always mean causation, because there might be a third variable that may have a better explanation for the correlation and it might as well means that the third-lurking variable affects the correlation; for example, those cars that are most frequently reported stolen may simply be the cars that are more commonly sold because they are cheaper than the cars that are stolen least often, and thus have a higher chance of being exposed to thieves.
