A study used a multiple choice exam with point ranges from 0–10 to measure subject knowledge of diabetic care. The exam score is an example of what level of measurement?
1. Ratio.
2. Interval.
3. Ordinal.
4. Nominal.
1
Rationale 1: Ratio level data have categories that are mutually exclusive and exhaustive, can be rank ordered, with equal distance between rank and no absolute zero.
Rationale 2: Interval level of measurement concerns data that not only can be placed into categories and ranked, but also requires that the distance between the ranks can be specified. Body temperature is an example of interval scale.
Rationale 3: Data that can be rank ordered, as well as placed into categories, are considered to be at the ordinal level of measurement. An example is categorizing anxiety levels such as mild, moderate, and severe.
Rationale 4: Nominal level of measurement includes mutually exclusive categories that are exhaustive. Examples are gender, religious affiliation, marital status, and political party membership.
