翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Frequency (statistics) ： ウィキペディア英語版 Frequency (statistics) In statistics the frequency (or absolute frequency) of an event $i$ is the number $n\_i$ of times the event occurred in an experiment or study. These frequencies are often graphically represented in histograms. ==Types of frequency== Cumulative frequency refers to the total of the absolute frequencies of all events at or below a certain point in an ordered list of events.〔 The relative frequency (or empirical probability) of an event refers to the absolute frequency normalized by the total number of events: : $f\_i\; =\; \backslash frac\; =\; \backslash frac.$ The values of $f\_i$ for all events $i$ can be plotted to produce a frequency distribution. 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 (statistics)」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
