Mechanism

Follow the mechanism step by step and distinguish what causes the change from what is merely observed.

This extension applies that lens specifically to Biostatistics Introduction.

Biostatistics Introduction

Study design, sampling, distributions, confidence intervals and hypothesis tests help distinguish signal from variation.
