Which of these is an example of Interval data?

  1. Temperature scales

  2. Weight

  3. Height

  4. Age

The correct answer is: Temperature scales

Interval data is a type of quantitative data that can be measured along a scale and has meaningful numerical values that indicate the differences between each point on the scale. The other options, weight, height, and age, are all examples of ordinal data, which can be placed in a specific order but do not have consistently meaningful numerical values between them. For example, while a person who weighs 150 pounds may be considered "heavier" than someone who weighs 130 pounds, it is not necessarily accurate to say that the first person is twice as heavy as the other. Age and height are similar in that they can be ranked in a specific order, but do not have consistent intervals between each point on the scale.
