the mode is that value that is repeated most often in the data set . 眾數(shù)是資料中重復(fù)出現(xiàn)次數(shù)最多的那個(gè)數(shù)值。
a frequency distribution shows the number of observations from the data set that fall into each of the classes . 頻率分布反映出落入每一組的觀察值個(gè)數(shù)。
this will help to overcome problems of apparent bimodality caused by the presence of many below-detection-limit values in a data set . 這將有助于克服因數(shù)據(jù)組中有大量低于撿出限的數(shù)值而出雙模態(tài)性的問題。
the relative frequency polygon has the same shape as the frequency polygon made from the same data set but a different scale of values on the vertical axis . 根據(jù)同一資料繪制的相對頻率多邊形與頻率多邊形的形狀是相同的,只是縱軸上的標(biāo)尺不同。
