The variables and their levels of measurements are:

  • Interval: Temperatures of passengers taken before boarding a flight
  • Ordinal: Rankings on a grading rubric (Mastery, Satisfactory, Unsatisfactory)
  • Ratio: Number of units each COS student is taking this semester
  • Nominal: Ice cream flavors

How to determine the level of the variables

There are four levels of variables

  • Nominal
  • Ordinal
  • Interval
  • Ratio

The nominal level of variable is a named variable, and they do not have any order.

So, the ice cream flavors can be categorized as a nominal variable because there can be as many flavors as possible

The ordinal level is used for rankings

So, rankings on a grading rubric can be categorized as an ordinal variable

The interval level is used for range

So, the temperature of passengers can be categorized as an interval variable

Lastly, the number of units is a ratio variable because it can take absolute zero as its value
