Which of the following is an example of a qualitative categorical or nominal variable?

A qualitative nominal variable is a qualitative variable where no ordering is possible or implied in the levels.

Eye color is another example of a nominal variable because there is no order among blue, brown or green eyes.

Is ZIP code qualitative or quantitative?

Some variables, such as social security numbers and zip codes, take numerical values, but are not quantitative: They are qualitative or categorical variables. The sum of two zip codes or social security numbers is not meaningful. The average of a list of zip codes is not meaningful.

Examples: Height, Weight, Time, Price, Temperature, etc.	Examples: Scents, Appearance, Beauty, Colors, Flavors, etc.

What are qualitative and quantitative variables?

Quantitative Variables – Variables whose values result from counting or measuring something. Examples: height, weight, time in the 100 yard dash, number of items sold to a shopper.

Which of the following variables are categorical?

Examples of categorical variables are race, sex, age group, and educational level.

What is an example of a qualitative variable in research?

Identify the qualitative variables and determine whether they are nominal, ordinal or dichotomous. In this example ID number, sex, age group, and educational level are all qualitative. Although ID number and age group are numeric, these values are used simply for grouping. Finding the average of these values would not be meaningful.

What is the difference between a quantitative and categorical variable?

A variable that contains quantitative data is a quantitative variable; a variable that contains categorical data is a categorical variable. Each of these types of variable can be broken down into further types.

Can an ordinal variable be a quantitative variable?

An ordinal variable can also be used as a quantitative variable if the scale is numeric and doesn’t need to be kept as discrete integers. For example, star ratings on product reviews are ordinal (1 to 5 stars), but the average star rating is quantitative.

Is a ZIP code quantitative or qualitative?
