Categorical vs Numerical Data Concepts

Mrs. Nelson introduces Unit 8, Lesson 1, focusing on understanding the difference between categorical and numerical data. She explains that numerical data consists of numbers, while categorical data consists of words. The lesson includes examples to help distinguish between the two types of data. Questions like 'What is your favorite breakfast food?' and 'How many teachers do you have?' are used to illustrate categorical and numerical data, respectively. The lesson concludes with a recap of the objective and key points.
