The following vocabulary will be important in this lesson:
- Data: A body of facts or information.
- Qualitative: descriptive information
- Quantitative: numerical information
- Discrete: only includes certain values (such as whole numbers)
- Continuous: includes any value (usually within a given range)
When asking a qualitative question, you would ask a question that results in an adjective or noun. These questions generally begin with "What"
Examples of Qualitative Questions:
- What color is your hair?
- What is your favorite pizza topping?
- What emotion did you feel about the teachers decision to give extra credit?
Examples of Quantitative Questions:
- How long, in inches, is your hair?
- How many toppings, on average, do you put on your pizza?
- How much extra credit did you receive last quarter?
Discrete Question: How many toppings did you put on your pizza?
Since answers to this question would be answers like 0, 1, 2, 3, etc. the data is discrete.
Continuous Question: How tall are you?
Since the answers could include things like 64.5 inches (not just whole numbers), the data is continuous.
