Types of Variables in Statistics

The video tutorial explains the difference between categorical and quantitative variables. Categorical variables classify data into groups, while quantitative variables provide measurements with units. Through examples, the video illustrates how the same data can be interpreted as either categorical or quantitative depending on the context. It emphasizes that numbers can represent categories, highlighting the importance of context in data interpretation.
