What is Frequency in Probability & Statistics?
What does frequency mean in statistics or probability theory? Frequency is the number of times an event occurs in any experiment. For example, consider the experiment to be the tossing of a coin. Let an event be the falling of a coin with the ‘Heads’ side up. The frequency of the event that the coin falls with the head side up, would be the number of times that happens. Out of 10 coin tosses, if the coin falls with its heads up 4 times, then the frequency of that event is 4. Frequencies are often represented with the help of histograms in statistics. It is a graphical representation of the frequency count of each event drawn on a two dimensional graph. What is Absolute Frequency? Absolute frequency of the event is the actual number of times the event actually occurs during an experiment. In the above experiment the absolute frequency of the coin falling with its heads up is 4. What is Relative Frequency? The relative frequency of an event is the ratio of the absolute frequency of a par
