Question

The Sport Journal (Winter 2004) reported on a study of a speed-training program for high school football players. Each participant was timed in a 40-yard sprint both before and after training. The researchers measured two variables: (1) the difference between the before and after sprint times (in seconds), and (2) the category of improvement ("improved," "no change," and "worse") for each player. What is the type for the variable "improvement"?

A. Ordinal
B. Interval
C. Ratio
D. Nominal

Answer 1

Ordinal

Explanation:

The definition of ordinal type of variables states that "if the variable has meaningful ordering or the data values of variable can be arranged in ranking then the variable is ordinal"

Here are some examples of ordinal variable to have a clear idea about it.

i) Ratings of product i.e. Excellent,good,fair, worse.

ii) Grades in exam i.e. A,B,C,D and F.

iii) Ranks in army.

iv) Ranks in sports team.
