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’与SPSS数据文件‘norms.sav’，以及R语言脚本文件‘norms.R’与R语言数据文件‘norms.Rdata’。假定上述文件已保存至目录‘C:mydir’，如有需要可将该路径修改为其他目录。请注意，SPSS中的NORMS函数仅支持单个参数，且对带有值标签的变量无法正常运行。输出结果将包含每项范数统计量的点估计值、标准误（Standard Errors，SEs），以及基于瓦尔德法构建的置信区间的下限（LO）与上限（UP）。
