It compares observed frequencies (what you actually count) to expected frequencies (null hypothesis prediction), helping researchers assess whether differences are due to chance or a real relationship in the population.When to use chi-square test vs t test?Use a chi-square test for categorical data to assess relationships between variables. Use a t-test for comparing means of continuous data, typically between two groups. Chi-square examines frequency distributions, while t-tests analyze differences in averages of numerical data.
