The Interval and Ratio Scales

Interval scales have equal intervals between values but no true zero, while ratio scales have a true zero, allowing for a full range of mathematical operations.

Examples

• Temperature: Measuring temperature in degrees Celsius or Fahrenheit, where the difference between values is meaningful, but there is no true zero point.
• Height: Measuring height in centimeters or inches, where a true zero exists, allowing for meaningful comparisons and mathematical operations.
• Weight: Recording weight in kilograms or pounds, where a true zero point allows for meaningful ratios and comparisons.
