Standard Errors and Confidence Intervals of Norm Statistics for Educational and Psychological Tests Dataverse

This folder contains the SPSS macro ‘norms.sps’ and the SPSS data file ‘norms.sav’, and the R script file ‘norms.R’ and the R data file ‘norms.Rdata’.

It is assumed that the files have been saved in the directory ‘C:\mydir’. This can be changed to another directory if required.

It may be noted that function NORMS in SPSS can have one argument only, and does not work well for variables whose values have been given a value label.

The output contains for each norm statistic: the point estimates, the SEs, and the lower (LO) and upper (UP) bounds of the Wald-based confidence interval.

本文件夹包含SPSS宏文件‘norms.sps’、SPSS数据文件‘norms.sav’、R脚本文件‘norms.R’以及R数据文件‘norms.Rdata’。
假设文件已保存至目录‘C:mydir’。若有需要，可将其更改为其他目录。
需注意的是，SPSS中的NORMS函数仅支持单个参数，且对于已赋予值标签（value label）的变量表现不佳。
输出结果包含每个正态统计量的点估计值、标准误差（SE）以及基于Wald的置信区间的下限（LO）和上限（UP）。
