Categorical and Quantitative Variables

The video tutorial explains the difference between categorical and quantitative variables. Categorical variables group data into categories, while quantitative variables provide measurements with units. Through examples involving height, color, and age, the video illustrates how data can be classified into these types. It also discusses how context can change the classification of data, such as age being both a measurement and a category. The video concludes by summarizing the key points and emphasizing that numbers can represent categories depending on the context.
