Math AL COS 12 Recognize data as either categorical or numerical. Examples:categorical—gender, race, languages spoken, genre; numerical—age, height, weight Comparing related data sets

Numerical Data is considered to be “numerical” if it involves a NUMBER. For example: The question, “How old are you?” is looking for a NUMERICAL answer.

Categorical Data is considered to be “categorical” if it involves a CATEGORY, or simply - WORDS. For example: The question, “What color is your hair?” is looking for a CATEGORICAL or WORD answer.

Practice Categorical (Words) or Numerical? 1.How many days left until Christmas? 2.Where are my socks? 3.Whose team are you on? 4.What is the length of your shoe? 5.What time is it? 6.What state are you from? 7.How many windows are in the house?

More Practice Write your own Categorical and Numerical questions.
