Enter the joint relative frequency and the marginal relative frequency into the Calculator. The calculator will evaluate the Conditional Frequency. 

Conditional Frequency Formula



  • CF is the Conditional Frequency ()
  • JRF is the joint relative frequency
  • MRF is the marginal relative frequency

To calculate Conditional Frequency, divide the joint relative frequency by the marginal relative frequency.

How to Calculate Conditional Frequency?

The following steps outline how to calculate the Conditional Frequency.

  1. First, determine the joint relative frequency. 
  2. Next, determine the marginal relative frequency. 
  3. Next, gather the formula from above = CF = JRF / MRF.
  4. Finally, calculate the Conditional 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.

joint relative frequency = 0.58

marginal relative frequency = 0.9
