Answer #1

We know that variables which are measured in numerical values are Quantitative variable and variables which are measured in non numerical values are Categorical variables.

(1) Quantitative variables are median age and population because these variables are measured in numerical data values. Therefore, answer is median age and population.

(2) Categorical variables are college education, ethnicity ,employment and income levels because these variables are measured in non numerical data values, i.e. alphabetical values or labels. So, these four are categorical variables.
