Question

A statistics instructor collects the number of credit hours this semester and major of each student in a statistics class. Credit hours taken this semester is which level of measurement?

a) interval
b) ordinal
c) ratio
d) nominal

Answer 1

The number of credit hours taken by a student is measured at the ratio level of measurement because it is a quantitative measure with a true zero point, allowing for meaningful computation of ratios.

Step-by-step explanation:

The question asks about the level of measurement for the number of credit hours a student is taking this semester. The levels of measurement in statistics include nominal, ordinal, interval, and ratio. The number of credit hours is a quantitative measure that can be counted and has a true zero point (e.g., zero credit hours means a student is not taking any classes). Additionally, you can say that a student taking 6 credit hours is taking twice as many as a student taking 3 credit hours, which means ratios can be calculated. Therefore, the number of credit hours taken by a student falls under the ratio level of measurement.
