https://youtu.be/Fv-U-pZ4HbI#The Chi-Squared test determines whether there’s a significant association between categorical variables.#It compares the observed frequencies (counts) to the expected frequencies, calculated under the null hypothesis that the variables are independent or that the observed distribution fits a given distribution. #Chi-Squared Goodness-of-Fit Test#This test assesses if the observed frequencies for a single categorical variable match […]
