- Frequency is a term used to describe how often something happens over a set period of time. When we talk about frequency in the context of waves, we're looking at how many complete cycles of the wave occur in one second. This is measured in Hertz (H z). For example, if a wave completes 10 cycles in one second, its frequency is 10 H z.

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}}
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.
The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.
Cumulative Frequency. Cumulative frequency is the number of times that anything up to and including that value (or group of values) appeared. You will need to be able to work out the cumulative frequency as well as use this to plot a cumulative frequency graph.
