效应量是指由于因素引起的差别,是衡量处理效应大小的指标。与显著性检验不同,这些指标不受样本容量影响。它表示不同处理下的总体均值之间差异的大小,可以在不同研究之间进行比较。平均值差异、方差分析解释比例、回归分析解释比例需要用效应量描述。效应量不受样本容量的影响。当样本容量大得到显著时,有必要报告效应量大小。
效应量(effect size)是指有临床意义的观察指标的变化量,如上述观察指针为分类变量数据时,效应量采用绝对危险度AR、相对危险度RR、比数比OR等表示;...

但是若干研究的结果是一致的,效应量很大。
But the results were consistent over a number of studies, and the effect size is large.
例如,平均来说,本的试验表明的效应量为。20(出自0 - 1的概率范围)。
For example, on average, the Bem studies showed an effect size of.20 (out of a possible range of 0-1).
目的:探讨医学研究中方差分析常用的效应量——标准均数差的计算方法。
AIM: To explore the standardized mean difference, the common effect size for ANOVA in medical research.
And the point that I also want to make is the way that they differ, z effective actually differs from the total charge in the nucleus due to an idea called shielding.
我也想指出的一点是它们不同的方式,有效的z事实上不同于原子核的,总电荷量,因为屏蔽效应。
