WebHowever, the math for Cramér's V is straightforward: V = χ 2 / n min ( rows-1, cols-1) which in your case simplifies to: V = χ 2 n. By definition, the p -value of V is equal to the p -value of the corresponding χ 2 (as you can plainly see in the edit to your question which now includes the output from the chisq.test command). WebOct 20, 2024 · The effect size of the χ2 test can be determined using Cramer’s V. Cramer’s V is a normalized version of the χ2 test statistic. It is defined by V = √ χ2 n ⋅ (c − 1) where n is the sample size and c = min (m, n) is the minimum of the number of rows m and columns n in the contingency table. Interpretation of Cramer’s V is easy due to V ∈ [0, 1]. ericsson tech day 2022
