Marginal Relative Frequency (Marginal Proportion) Formula

The following example problem outlines the steps and information needed to calculate the marginal relative frequency. (In a two‑way table, the marginal frequency is the row or column total itself; dividing by the grand total gives the marginal relative frequency.)

MF = RT / GT

Variables:

  • MF is the marginal relative frequency (marginal proportion; unitless)
  • RT is the row total or column total (a marginal frequency / count)
  • GT is the grand total (total count)

To calculate the marginal relative frequency, divide the row or column total by the grand total.

How to Calculate Marginal Relative Frequency?

The following steps outline how to calculate the marginal relative frequency.

  1. First, determine the row total or column total (this is the marginal frequency as a count).
  2. Next, determine the grand total.
  3. Next, use the formula: MF = RT / GT.
  4. Finally, calculate the marginal relative frequency.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

row or column total (RT) = 3

grand total (GT) = 10

MF = RT / GT = 3 / 10 = 0.3 = 30%
