He coined the term 'Strong Inference'

The kind of world we live in.

The "cause" of the Greek debt crisis

The validity of inferences about whether the relationship between two variables is causal

The #1 confound

1) Specify the statistical hypotheses

4) Assess goodness of fit/effect size
5) Test hypotheses on the model parameters
6) Assess the adequacy of the model
7) Make a decision

In this model, error exists

Surface similarity, ruling out irrelevancies, making discriminations, interpolation and extrapolation, causal explanation
