Are age groups nominal or ordinal?

Can Anova be used for categorical data?

A one-way analysis of variance (ANOVA) is used when you have a categorical independent variable (with two or more categories) and a normally distributed interval dependent variable and you wish to test for differences in the means of the dependent variable broken down by the levels of the independent variable.

How do you handle categorical data?

Is age categorical or quantitative?

In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values. It also makes sense to think about it in numerical form; that is, a person can be 18 years old or 80 years old. Weight and height are also examples of quantitative variables.

What is the difference between a nominal and ordinal variable?

Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.

What do you mean by categorical data?

How do you identify categorical variables?

3 Answers. You could say that some variables are categorical or treat them as categorical by the length of their unique values. For instance if a variable has only unique values [-2,4,56] you could treat this variable as categorical. Every unique value in every variable treated as categorical will create a new column.

Is weight an ordinal variable?
