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].

In statistics, Cramér's V (sometimes referred to as Cramér's phi and denoted as φc) is a measure of association between two nominal variables, giving a value between 0 and +1 (inclusive). It is based on Pearson's chi-squared statistic and was published by Harald Cramér in 1946. WebBecause both of these variables are categorical with two or more possible values per variable, we know that Cramer’s V is a suitable test. The analysis will result in a Cramer’s V value and a p-value. Cramer’s V ranges from 0 to 1, where 0 indicates no relationship and 1 indicates perfect association. The p-value represents the chance of ... WebAs far as interpretation of results is concerned, Cohen's guidelines are commonly used.
