Types of variables

You further analyzed the data you collected last week and made a claim about whether we can use the x-value to predict the y-value for your experience.

We discussed many types of variables in class today, focusing on quantitative (discrete and continuous) and categorical.

Create a list of 20 clever variables and identify whether each is quantitative or categorical. Include both types in your list. If the variable is quantitative, determine whether it is discrete or continuous.

Examples:

The number of students in math classes at Lassiter: quantitative and discrete.
The number of minutes of studying/homework done by students each night: quantitative and continuous.
The math course taken by students at Lassiter: categorical. [The values that the variable can take are the different courses.]
