Bug Description

The variables in the example dataset "Age and Fatigue" are supposed to be z-standardized. However, the variable "AudAttention" has a standard deviation of 1.559 which may lead to confusion (e.g., in a simple linear regression of AudAttention -> fatigue, the unstandardized coeffiecent is not equal the standardized coefficent).

Sorry, if "Bug" is the wrong category for this.

Expected Behaviour

standard deviation should be 1

Steps to Reproduce

1. calculate standard deviation of AudAttention

Log (if any)
