How many people were killed in World War II?  What were the deciding battles in World War I?  As these monumental wars transformed the world and the future of the world, I'd expect answers to simple questions like this to be almost part of our vocabulary.  But they're not.

However, if you ask me about Napoleon, his march on Moscow, how many men did he start with, how many remained, etc., I can answer every question.  Why?  The power of a good graphic.

SHEWHART'S RULES

for the presentation of data

 

THE FIRST RULE

Original data should be presented in a way that will preserve the evidence in the original data for all the predictions assumed to be useful.

 

THE SECOND RULE

Any summary of a distribution of numbers should not give an objective degree of belief in any one of the inferences or predictions to be made there, for that would cause human action significantly different from what this action would be if the original distribution had been taken as a basis for evidence.

SHEWHART'S RULES

for understanding data

 

THE FIRST RULE

No data have meaning apart from their context.

 

THE SECOND RULE

While every data set contains noise, some data sets may contain signals.  Therefore, before you can detect a signal within any given data set, you must first filter out the noise.
