1.) How many days until you graduate from CSU? This would be the interval or ratio scale of measurement.
2.) How many hours per week do you spend on your classes? The question is an interval or ratio scale of measurement.

Two qualitative questions:
1.) Where is your favorite place to study? Use the number 1 for home, or the number 2 for another location. This is a categorical question with a categorical variable.
2.) How would you rate your commitment to your CSU classes
