单因素方差分析:(One-Way Analysis of Variance)数学中常用的数据统计和分析的方法。
称完全随机设计资料方差分析。比较数值间差别水平的一种统计方法。将研究对象随机分配到一个因素多个水平中去,按某个研究因素的不同水平分组,比较不同水平下各组平均值之间的差别是否有统计学意义。此分析方法适用于对单因素多个独立样本均值的比较,各组均数应来自正态分布且方差齐的资料。例如观察不同剂量的同一营养素,对动物生长发育的影响研究即可应用此法。参见“完全随机设计资料方差分析”。
Call completely random design data variance analysis. Compare the method of a kind of statistic of level of the difference between numerical value. research the object distributes an element randomly go in many levels, by a certain research the different water of the element deuces group, whether does the difference between each groups of average below more different level have statistical sense. This analysis method applies to what to only factor many independent example all are worth to compare, each groups all are counted should come from normal school and the data with neat variance. Observe the same nutriment of different dosage for example, grow to the animal the influence research of development can use this method. Refer to " variance analysis of data of completely random design " .
