Question

If a study was done that asked college students exactly how many A’s they have obtained (e.g., 0, 1, 2, etc.), the researcher is using:

A nominal measure

An ordinal measure

An interval measure

A ratio measure

Answer 1

Answer- A ratio measure

Explaination- In a ratio scale ,data has measurable intervals.It differs from the interval scale is that it also has a meaningful zero. The zero in a ratio scale means that something doesn’t exist. So in this if the number is not existing then we can consider it as zero.But there is no such kind of quality in Interval measure.Yes it has equal interval as ratio scale but no chance of getting zero data.Comparatively,nominal and ordinal are good in measuring the quality not quantity like low,slow, high etc or rank of something.So as fro the given example , the A"s can be obtained 0,1 ,2 etc. in a ratio scale with equal intervals.
