The video tutorial covers the basics of two-way tables, including their structure and how to interpret them. It explains the concept of relative frequency and how to calculate it using examples. The tutorial also includes practice questions to reinforce understanding and application of two-way tables. Students are encouraged to complete a worksheet and submit it for review.
