Answer to Question 1

4
Rationale 1: Data that can be rank ordered, as well as placed into categories, are considered to be at the ordinal level of measurement.
Rationale 2: Ratio level of measurement includes data that can be categorized and ranked; in addition, the distance between ranks can be specified, and a true or natural zero point can be identified.
Rationale 3: Interval level of measurement concerns data that not only can be placed into categories and ranked, but also the distance between the ranks can be specified.
Rationale 4: Data measured by a quantitative difference between categories that are mutually exclusive and mutually exhaustive is nominal level data.

Answer to Question 2

3
Rationale 1: Face validity is an estimation of validity based on a preliminary examination to see if it measures the concept.
Rationale 2: Construct validity refers to the degree an instrument measures the construct it is supposed to measure.
Rationale 3: Content validity for an instrument is concerned with the scope or range of items used to measure the variable. Content validity can be determined by a panel of experts.
Rationale 4: Criterion validity compares the instrument's ability to measure subjects' behavior with some other criterion (measure) of that same behavior.
