- Frequency is how many times something happens in a certain amount of time. It's like counting how many times your dog barks in a minute. Like if we know the speed of a wave, we can find its frequency. Imagine a wave like a roller coaster; how fast it goes up and down tells us its frequency.

Frequency tables can be used to draw bar charts, pie charts or histograms. They can also be used to find cumulative frequency which in turn can be used to estimate median values and upper and lower quartiles for grouped data.
We can calculate frequency using specific formulas that take into account other related quantities like time period, wave speed, and wavelength. These formulas help us understand the behavior of waves and how they propagate through space. Formula 1: Frequency formula based on time period (T): f = 1 T.
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.
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.
We can have all of them in one equation: y = A sin(B(x + C)) + D. amplitude is A; period is 2 π /B; phase shift is C (positive is to the left) vertical shift is D; And here is how it looks on a graph: Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation.

A frequency graph is a way of representing a set of data (a frequency distribution). To represent data using a frequency graph we need to know which type of graph would be preferable for the data we are representing (and be able to justify why this type of frequency graph has been chosen), and how to draw each type of frequency graph.
