In statistics, a frequency distribution is a table that displays the frequency of various outcomes in a sample.〔Australian Bureau of Statistics, http://www.abs.gov.au/websitedbs/a3121120.nsf/home/statistical+language+-+frequency+distribution〕 Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample. ==Univariate frequency tables== An example of a univariate (i.e. single variable) frequency table. The frequency of each response to a survey question is depicted. : A different tabulation scheme aggregates values into bins such that each bin encompasses a range of values. For example, the heights of the students in a class could be organized into the following frequency table. 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 charts, bar charts and pie charts. Frequency distributions are used for both qualitative and quantitative data. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Frequency distribution」の詳細全文を読む スポンサード リンク
