Question

Provide an example of each of the levels of measurement:

1. Nominal: They are used as names/labels, for example hair color, gender, favorite food.

2. Ordinal: They are used to show significance. For example, a scale that says how happy are you ranging from “Upset to Very Happy”.

3. Interval: A scale where each value knows the order and the difference between each value. For example, the temperature, there is a measurable 10-degree difference between 50 and 60 degrees.

4. Ratio: They tell the exact value between things and have an absolute zero. An example of ratio would be height and weight.

Answer 1

NOMINAL : It is name variable or we can say categories without order and direction. Eample :

Type of cars or Marital status(Married /unmarried/Divorced) or Gender (Male /Female)

Ordinal: It is ranking variable . For example

First Division, Second Division..

Service quality ratings( Bad/ Good/Best/Excellent)

Interval: Diferences between measurements but no true zero.

Example:( Temperature measurement in Fahrenheit, student grade scores)

Ratio: Differences between measurements but true zero exist.

Example: (Weight. Income , Age , Height)
