Quiz 3: Consumer Behavior
Business
Q 1Q 1
Gary Franklin is a movie critic.He invented the Franklin Scale with which he rates movies from 1 to 10 (10 being best).When asked about his scale,Mr.Franklin explained "that it is a subjective measure of movie quality.A movie with a ranking of 10 is not necessarily 10 times better than a movie with a ranking of 1,but it is better.A movie with a ranking of 5 is better than a movie with a ranking of 1,but is not as good a movie with a ranking of 10.That's all it really tells you." Based on Mr.Franklin's description,his scale is:
A)ordinal but not cardinal.
B)cardinal but not ordinal.
C)an objective standard to judge movies.
D)neither cardinal nor ordinal.
