Below are five questions from a survey of MBA students. Answers were written in the blank at the left of each question. For each question, state the data type (categorical, discrete numerical, or continuous numerical) and measurement level (nominal, ordinal, interval, ratio). Explain your reasoning. If there is doubt, discuss the alternatives.

1. What is your gender? (Male = 0, Female = 1)

2. What is your approximate undergraduate college GPA? (1.0 to 4.0)

3. About how many hours per week do you expect to work at an outside job this semester?

4. What do you think is the ideal number of children for a married couple?

5. On a 1 to 5 scale, which best describes your parents? (1 = Mother clearly dominant ⟷ 5 = Father clearly dominant)
