1.2.C—Identify types of quantitative variables

Identify types of quantitative variables.

• A discrete quantitative variable can take on a countable number of values. The number of values may be finite or countably infinite, as with the whole numbers.
• A continuous quantitative variable can take on an infinite number of possible values within a given interval. The number of values the variable can take on is measurable but not countable. This variable can take on all possible values between any pair of values.
