What is the primary function of a two-way table?

The primary function of a two-way table is to organize information regarding two categorical variables, allowing for the examination of the relationship between them. This type of table arranges the data in rows and columns, where each row represents a category from one variable and each column represents a category from the other variable. By arranging the data this way, it becomes easier to analyze how the two variables interact with each other. For example, a two-way table could be used to display the relationship between students' grade levels and their preferred subjects, facilitating comparisons and insights into trends or correlations. This organizational structure makes two-way tables a valuable tool for statistical analysis in various fields such as education, sociology, and market research.
