Exploring data: observing patterns and departures from patterns using graphical and numerical techniques. Note distribution, shape, location, variables, unusual values.
Planning a study: deciding what and how to measure, identifying important variables related to conjecture, specifying how they are to be measured and formulating a model from which inferences can be drawn.
Anticipating patterns: producing models using probability and simulation. Probability is oriented toward describing data distribution, rather than axiomatic or combinatorial focus.
Statistical inference: confirming models. Use models to draw conclusions from data; use data to critique modes.
