Answer: 1. ratio scale
2. ordinal scale
3. nominal scale
Explanation:
Ratio scale can be defined as the measurement in which the variables are measured using specific numerical values that have equal distances between the variables. The variables are based on the true zero points.
An ordinal scale is a scale or measurement which uses the labels to classify cases into ordered classes.
Nominal Scale can be defined as a scale, in which numbers work as labels to identify an object. A nominal scale measurement deals with non-numeric variables. Here, the numbers have no value.
