Association between 2 categorical variables Chi-square

The main idea of the video is to introduce the chi-square test, a statistical method used to determine if there is a relationship between 2 categorical variables. The video explains that unlike correlation methods for continuous variables, the chi-square test compares the observed distribution of data to the expected distribution if the variables were independent. It demonstrates the process of conducting a chi-square test using a car dataset to analyze the relationship between fuel type (gas or diesel) & aspiration (standard or turbo). The video also shows how to perform the chi-square test in Python using the `scipy.stats.chi2_contingency` function.
