This video shows how to transform continuous variables toward normality in SPSS. If you would like to watch a video on applying the TwoStep transformation to normality in Excel, watch this video:    • A TwoStep Transformation to Normalit...  .

This approach outputs one of two optional units: 1) original series mean and standard deviation 2) zscores (mean=0, standard deviation=1).

Use of this method can be justified by citing the following published papers:
