Frequency (statistics)
In statistics, the number of times an event occurs. For example, in a survey carried out to find out a group of children's favourite colour of the rainbow, the colour red is chosen 26 times. This gives the colour red a frequency of 26. A table of the raw data collected, including the frequencies, is called a frequency distribution. It is usually presented in a frequency table or tally chart. The frequencies can also be shown diagrammatically using a frequency polygon.
