Question

Based on the information provided, the lecturers made sure the different levels of performance were represented [from below average to above average] when selecting students. Which scale of measurement will be applicable?

1. Nominal.

2. Ordinal.

3. Interval.

4. Ratio.

Answer 1

ANSWER : "ORDINAL" scale of measurement will be applicable.

The ordinal scale is the 2^nd level of measurement. Ordinal data is known as qualitative data or categorical data.

In the given scenario the levels of performance of the students (viz. below average, average, above average) only shows the rank-order neither the difference nor the ratio. So the ordinal numbers do not indicate absolute quantities; nor do they indicate that the intervals between the numbers are equal.
