AP Statistics | Unit 3 Review | Collecting Data (EVERYTHING YOU NEED TO KNOW!!)

Darren covers AP Statistics Unit 3 content for the midterm and reviews topics such as:

Collecting Data: Understanding the differences between surveys, experiments, and observational studies, and when to use each method.
Sampling Methods: Identifying simple random samples, stratified random samples, cluster sampling, and systematic sampling, as well as recognizing sources of bias.
Experimental Design: Key principles including random assignment, control, replication, and blocking.
Bias and Confounding: Identifying types of bias (e.g., undercoverage, response bias, nonresponse) and understanding how confounding variables can affect results.

This review focuses on designing valid studies and ensuring conclusions are supported by the method of data collection.
