Expert Answer

Step 1


Nominal data:

  • This type of variable is used to label the variables without any quantitative values.
  • It can be named but not ordered.
Step 2

  • This is categorical variables.
  • This type of variables are divided into group.
  • Example: gender, eye color.
  • It can be ordered, but the difference has no meaning.


Step 3

Interval data:

  • It is an integer,
  • This data always appear in the form of numerical values where the dista...
