# Foundations for Statistical Inference

Study Design, Inference using randomization and the Normal Model

9/27-10/9

## Learning Path

### Where we’ve been

- Learning how to explore and visualize our data.
- Visually consider patterns, identify potential relationships

### Where we’re at

- Think about how data come to be. That is, if the data are to be used to make broad and complete conclusions, then it is important to understand who or what the data represent.
- Knowing how the observational units were selected will allow for generalizations back to the population from which the data were selected.
- By understanding the structure of the study, causal relationships can be separated from those relationships which are only associated.

- Revisiting null value hypothesis testing (NVHT) from a randomization perspective
- Revisiting the Normal distribution model, and getting a feel for how probability (and thus p-values) are calculated.
