What is the difference between categorical and quantitative data?

Back

Categorical data represents categories or groups (e.g., colors, types), while quantitative data represents numerical values that can be measured (e.g., height, weight).

What does it mean if a two-way table shows a high frequency in one category?

Back

A high frequency in one category indicates that a significant number of observations fall into that category, suggesting a strong preference or trend.
