Why a reviewer asks for random? Why we need to report effective size: f square?

[温馨回答]：

1. 为什么 reviewer要求交代（随机）random？2. 为什么要用effective size: f square? 

有老师们询问2个问题，一并回答如下:

 1. 为什么 reviewer要求随机？2. 为什么要用effective size: f square? 

Ans:

1.基本核心概念是，大样本排除了偶然性，随机排除了个体差异，双盲排除了主观偏向。

2. 调节分析中调节项影响大小己经不是由交叉乘项的系数（不精确），必须交待 f square, 才可以得知调节的影响大小，正确的调节分析和effective size: f square的标准请参考
