Question

In: Statistics and Probability

Nominal, ordinal , interval, ratio , dichotomous level of measurement with example

Expert Solution

Nomial level:

It is used with categorical variables. Here we cannot define order between the categories.

For example: Hair color, Car type

---------------------

Ordinal level:

It is used with categorical variables. Here we can define order between the categories.

For example: Food quality (bad, good, very good, excellent)

-----------------------

Interval level:

It is used with quantitative variables. Here zero does not mean absence of data. For example: temperature

If temperature is zero then it does not show absence of temperature.

-------------

Ratio Interval:

It is used with quantitative variables. Here zero means absence of data or no data. For example: distance

If distance is zero then it shows there is no distance between objects or missing distance

--------------------

Dichotomous level:

Here variable can have only two possible values. For example: Question that has only two possible answers: agree or disagree
