Question

Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate for the data below.

Course grades from Upper A to Upper F Choose the correct answer below.

A. The nominal level of measurement is most appropriate because the data cannot be ordered. nothing B. The interval level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is no natural starting point. C. The ordinal level of measurement is most appropriate because the data can be ordered comma but differences cannot be found or are meaningless. nothing nothing nothing nothing nothing D. The ratio level of measurement is most appropriate because the data can be ordered comma differences left parenthesis obtained by subtraction right parenthesis can be found and are meaningful comma and there is a natural starting point.

Answer 1

Different types of level:

If it is classified by names, so this is a nominal level of measurement.

Ordinal level if it consists of levels in order of magnitude, but the distance between levels is not quantifiable.

The interval level of measurement, because there is no absolute zero and values cannot be expressed as ratios

The ratio level of measurement because it has an absolute zero value and the difference between values is meaningful.

Course grades (A, B, C, D, E, F)
Course grades (A, B, C, D, E, F) are indicators of the quality of a student’s performance and are ordered, so this is an example of an ordinal level of measurement.

we know that which one is hight & low but we cannot know the exact distance between them but they are ordered.

so it is an ordinal level.

Answer:-  C. The ordinal level of measurement is most appropriate because the data can be ordered comma but differences cannot be found or are meaningless.
