Two-Way Frequency Tables and Variables

The video tutorial explains how to compare two sets of data using a two-way frequency table. It covers the identification of independent and dependent variables, the construction of the table, and provides examples using movie preferences and a uniform policy survey. The tutorial emphasizes the flexibility of variable placement and the importance of calculating totals for accurate data representation.

What is the primary purpose of a two-way frequency table?

• To determine the mode of a dataset

• To find the median of a dataset

• To compare two sets of data visually

• To calculate averages

Which of the following is an example of an independent variable?

• The total number of participants

In the school uniform survey, what are the two variables?

• Eye color and age

• Uniform opinion and eye color

• Gender and uniform opinion
