Talk:Qualitative variation

McIntosh's D
In the formula shown in the numerator it has the square root of the sum of all the counts (n_i). If I'm not mistaken this should be then the same again as N, making the numerator and denominator always equal.

I couldn't find the source for this measure and also non is listed. So difficult to understand what it actually should be. Stikpet (talk) 14:54, 25 June 2023 (UTC)
