Chi Square is a statistical test used to determine if there's a significant relationship between two categorical variables. It operates under the principle that the frequency of observations in each category will conform to the expected counts under a null hypothesis. Here's how it works: for a given dataset, you create a contingency table that displays the observed frequencies of each category. The observed frequencies are compared to the expected frequencies based on a null hypothesis, and the Chi Square value is calculated. This value determines the p-value, which indicates the probability of observing the Chi Square value by chance. If the p-value is below a certain threshold, we reject the null hypothesis, indicating dependence.
