AP Statistics | Unit 2 Review | Exploring Two-Variable Data (EVERYTHING YOU NEED TO KNOW!!)

Darren covers AP Statistics Unit 2 content for the midterm and reviews topics such as:

Exploring Two-Variable Data: Creating and interpreting scatterplots, describing relationships (direction, form, and strength), and identifying unusual features like outliers or clusters.
Correlation: Understanding and calculating the correlation coefficient, interpreting its value, and distinguishing between correlation and causation.
Linear Regression: Fitting a least-squares regression line, interpreting slope and y-intercept in context, and using the regression equation for predictions.
Assessing Model Fit: Analyzing residual plots, identifying patterns, and calculating the coefficient of determination to evaluate how well the model explains variability.

This review emphasizes connecting context to statistical analysis and ensuring models are appropriate for the data.
