Question

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

Student's grades, A, B, or C, on a test.

Ordinal
Ratio
Interval
Nominal

Answer 1

ordinal (e.g A, B, C grade)
ratio = x/y (could use such as 51/100)
interval (i.e. grade between one value and another, not very enlightening)
nominal = number(e.g. 51, but not very enlightening)

best idea would be ordinal
