What is Frequency Distribution?

• A common, very helpful way to summarize data collections method shows the frequency (no. of occurrences) in each of several categories.

• Frequency Distribution can be summarize large volume of data values so decision makes can extract useful information directly from the collection.

• Frequency Distribution is a tabular arrangement of data showing its classification or grouping according to magnitude or size.

• Large masses of data presented without any arrangement or classification given very little information. In order for these data to give useful information they should be summarized or organized into a reduced form more appropriate for an effective analysis. One way of doing this is to summarize the data and compress them into a frequency distribution.
