Constructing a frequency table

Constructing a frequency table.

  • Organise the data before calculating.
  • Check counts and totals, and keep units or context in your conclusion.
  • Choose a typical-value measure and a spread measure that suit the data.

Example 1

Black: given data. Blue: working we add.

Count how often each distinct value occurs. List values in order and check the frequencies sum to the number of observations.
The frequencies total 9.
