Relative Frequency Formula

About Relative Frequency Formula

The term 'relative' is used to describe how an occurrence is viewed about or in proportion to something else. Frequency is a metric for determining how frequently an event occurs. Relative frequency, on other hand, is a technique of comparing the frequency of a certain event to the overall number of occurrences.

What do you mean by Relative Frequency Formula?

Several times an event occurs divided by the total number of events occurring in the given scenario is known as relative frequency.

Two things must be understood to compute the relative frequency:

total number of events/trials

Count frequency for a category/subgroup

The relative frequency formula will be given as:

Relative Frequency = frequency of Subgroup / Total frequency

Or

Relative Frequency = f/ n

Here, f is the number of times the data occurred in an observation

n= total frequencies

Solved Example of Relative Frequency 

Example: After 30 tosses, a cubical die lands 5 times on the number 6. What is the probability of seeing the die land on the number six?

Sol:

  1. It is given that the number of times a die is tossed = 30
  2. Number of successful trials of getting the number 6 = 5

By the formula, we get,

Relative frequency =Number of positive trials / Total number of trials

f = 5/ 30 = 16.66%

Answer: Relative frequency of observing die land on number 6 is 16.66%
