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.
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}}
In the frequency formula, f = 1/T, T is the time period. T refers to the time to complete one cycle (in seconds). Time period is inversely proportional to the frequency. The frequency formula is used to find the frequency of the wave.
