# Relative Frequency

Frequency refers to the total number of observations of a determined type. Based on the given problem frequency of a value can be expressed in different ways. In a simplest way frequency can be expressed in its absolute terms. Absolute frequency refers to the number of times a particular value for a variable has been observed to occur.

Relative frequency is also calculated by dividing the absolute frequency by the total number.

To find relative frequency we divide the number of observations of a certain type with its total. All the relative frequencies add up to 1.

It is also known as empirical probability. It is how often something happens over all the outcomes.

**For Example :** When a coin is flipped 8 times and you get tails 3 times then the relative frequency will be 3 over 8.
