bad example: sliding on the surface

Most SAS teaching at many universities are of the style "sliding on the surface".
It has the following features:
1) it teaches you how to find the right answers to your statistical problems using a SAS procedure or statement.
2) it uses SAS default outputs to present the results.
3) it assumes the data are ready for analysis without asking the basic questions about how the data come along and how as statisticians we should manipulate and process the data before we can use them.
