Question

Answer 1

Answer: B.  Quantitative

The question is what type of variable is this scenario?

A. Categorical

B.  Quantitative

There are two types of variables used in statistics: Quantitative and categorical ( or qualitative). Quantitative variables are variables that can be counted in counts or numbers or can be measured in percentage. Categorical variables are descriptions of groups or things.

In our scenario, we use quantitative variables (Vit C in milligrams) and risk of allergies (30%).
