Chi-Squared Test

Use: The Chi-Squared test is used to determine if there's a significant association between two categorical variables. It helps assess whether there is a relationship between the variables or if they are independent.

Example: Investigating whether there is an association between gender (male or female) and the preference for a particular brand of soft drink.

Column Requirement: Categorical data for both variables.


  1. Select two categorical columns (e.g., gender)

  2. Ensure expected frequencies in each cell of the table are not too low (generally above 5) for reliable results.

  3. Compute the Chi-squared test statistic.

  4. Evaluate the p-value associated with the test statistic.
