WebThe Chi Square test allows you to estimate whether two variables are associated or related by a function, in simple words, it explains the level of independence shared by two categorical variables. For a Chi Square test, you begin by making two hypotheses. H0: The variables are not associated i.e., are independent. (NULL Hypothesis) WebJan 27, 2024 · Data. For our example, let’s reuse the dataset introduced in the article “Descriptive statistics in R”. This dataset is the well-known iris dataset slightly enhanced. Since there is only one categorical variable and the Chi-square test of independence requires two categorical variables, we add the variable size which corresponds to small if …
