Interpreting Two-Way Tables and Frequencies

This video tutorial introduces two-way tables, explaining their structure and purpose. It covers key concepts such as joint and marginal frequencies, using examples like student surveys on studying habits and test results. The tutorial includes exercises on interpreting and creating two-way tables with various data sets, such as football game attendance and lunch packing habits. The video aims to enhance understanding of bivariate data analysis.
