Answer to Question 1

A

Answer to Question 2

B
Feedback:
There are four levels of measurement: (1) nominal measurementthe classification of attributes into mutually exclusive categories such as blood type; (2) ordinal measurementthe ranking of people based on their relative standing on an attribute such as type of college degree; (3) interval measurementindicati ng not only people's rank order but the distance between them; and (4) ratio measurementdistingu ished from interval measurement by having a rational zero point. College degrees are examples of ordinal measures, because they indicate a person's relative standing in terms of education, but do not indicate the distance between the measures.
