Additional Information

• Nominal scale
  • The nominal scale classifies data into distinct categories without any order or ranking.
  • Examples include gender, ethnicity, and hair color.
• Ordinal scale

  • However, the intervals between the ranks are not necessarily equal.
  • Examples include educational level, customer satisfaction ratings, and letter grades.

  • The interval scale classifies data into ordered categories with equal intervals between the categories.
  • However, it does not have an absolute zero point.
  • Examples include temperature scales like Celsius and Fahrenheit.
