MISUSE OF STATISTICS
 
These pages contain a sampling of the information presented in the four hour course, Misuse of Statistics.   The course contains eight modules.

The course avoids detailed calculations requiring advanced mathematics, physics, or engineering knowledge.   The course is not intended to show how to do statistics, but how to use them (and how they can be misused).   For this reason the course can be taken by both engineers and managers.   The course is suitable for both experienced engineers and novice engineers.

 
 
COURSE APPROACH
 
This course examines eight rules of statistics:
 
 
1.
Avoid False Precision;
 
2.
Beware The Base Rate Fallacy;
 
3.
Correlation Is Not The Same As Causation;
 
4.
Determining The Effect Of A Single Variable;
 
5.
You Must Have Substantial Differences To See An Effect;
 
6.
There Is Value In Longitudinal Studies;
 
7.

There Must Be Substantial Differences From Chance (this includes several exercises on sample size problems);
 
8.
Only A Dose-Response Relationship Proves Cause and Effect.
