    • In statistics, a frequency distribution is a tabulation of the values that one or more variables take in a sample.

      A Frequency Distribution shows us a summarized grouping of data divided into mutually exclusive classes and the number of occurrences in a class. It is a way of showing unorganized data e.g. to show results of an election, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc. Some of the graphs that can be used with frequency distributions are histograms, line graphs, bar charts and pie charts. Frequency distributions are used for both qualitative and quantitative data.

    • Bivariate joint frequency distributions are often presented as two-way tables:
    • The total row and total column report the marginal frequencies or marginal distribution, while the body of the table reports the joint frequencies.

    • Frequency Distribution: The tabulation of raw data obtained by dividing it into classes of some size and computing the number of data elements (or their fraction out of the total) falling within each pair of class boundaries. The following table shows the frequency distribution of the data set illustrated by the histogram below.
