• Quantitative data measures an amount and can be ordered from smallest to largest.

  • Categorical data specifies qualities and is not subject to the laws of arithmetic — for example, we cannot take the “average” of a list of colors.

Note: Numbers can sometimes be categorical rather than quantitative!

For each piece of data below, circle whether it is Categorical or Quantitative.
