Relative frequency is the number of times an event happens divided by the total number of outcomes that took place in an experiment, known as the number of trials. To calculate the relative frequency we can use the formula, \text{Relative frequency = }\frac{\text{frequency of event occurring}}{\text{total number of trials of the experiment}}

The frequency formula is used to find the frequency of a wave. Frequency is defined as the number of cycles completed per unit time. It also tells about how many crests go through a fixed point per unit time. Sometimes it is known as reciprocal of time. Frequency is expressed in Hertz (Hz).
Frequency is the number of times a particular value occurs in a set of data. Usually we would record the frequency of data in a frequency table. Example: Using the key: H = Hockey, B = Badminton, F = Football, each letter below indicates a student joining the sports club. H H B F B H F F H B.
Example: Finding the Median and IQR. Using the cumulative frequency graph below, calculate the median and interquartile range. [3 marks] There are 92 people in total, so the lower quartile, median, and upper quartile will be the 23 rd person, 46 th person, and 69 th person respectively.
