Question

Classify the variables A to F as qualitative or quantitative. For quantitative data, please state whether the variable is discrete or continuous. Then, for each one, distinguish between the four (4) levels of measurement (nominal, ordinal, interval and ratio).

What is the total cost of textbooks for your courses?

How many times do you see your Academic Advisor during the semester?

How do you rate the Add/Drop period? Very good/ Good/ Bad

Answer 1

Total cost of textbooks can be measured in numbers. Thus it is a quantitative data. Also, it is a ratio scale of measurement, as the exact differences between two values of cost can be measured and an absolute zero is there as well indicating the absence of any cost.

The rating of Add/Drop period cannot be measured in numbers, it can only be represented as Very good/Good/Bad. Thus it is a qualitative data. Also, it is a ordinal scale of measurement, as only the order is known and not the difference between each rating.
