Mathematics: the logic of certainty.

Statistics: the logic of uncertainty.

 

Certainty/Uncertainty:

    Phenomenon • Result

 

Phenomenon -> Observation -> (Certainty, Uncertainty)

 

Trial/Test:

• within same conditions;
• Observe objective phenomenon.

 

Statistical law:

    certain laws existed in enormous amount of repeated trials.

 

Random Phenomenon:

    a kind of phenomenon, show statistical laws in enormous amount of repeated trials.

 

The theory of Probability:

    A subject to do research on random phenomenon.
