Exploring Two Way Relative Frequency Tables

Mr. Millanes introduces two-way relative frequency tables, explaining their use in tracking two sets of data, such as gender and basketball performance in a class experiment. He demonstrates how to convert raw data into percentages, using a step-by-step approach to create a two-way relative frequency table. The video concludes with verifying totals and ensuring the table represents all students accurately.
