Answer:
a. Quantitative discrete variable. Ratio measurement scale.
b. Categorical variable Nominal measurement scale
c. Quantitative discrete variable. Ratio measurement scale.
d. to. Quantitative discrete variable. Ratio measurement scale.
Step-by-step explanation:
A categorical variable is one that does not refer to a quantification of any characteristic of the individual.
A numerical variable is a variable that reflects a quantifiable characteristic of an individual. If the quantifiable characterization is a measurement, the variable is considered continuous, while, if the characteristic is a count, the variable is considered discrete.
