Determine the level of measurement of the variable. Positions of runners in a race. A nominal. B ratio. C interval D. Ordinal

Answered by admin @ 28/10/2021

Answer: D. Ordinal

Step-by-step explanation:

There are four levels of measurements scales of a variable :-

Nominal scale : Used for categorical data on the basis of the characteristic like sex, religion color, etc.
Ordinal scale : Used to order the attributes as per their ranks such as First ,Second , Third and so on.
Interval scale : Used when the difference between any two values can be calculated and has meaning such as Fahrenheit scale to measure temperature.
Ratio scale : It accommodates all the qualities of the 3 measures and in addition a "true zero" point. For example : Age.

Positions of runners in a race comes in ordinal scale because we need to order them with their respective rank.

So, the correct option is D. Ordinal
