Lesson 1
Bivariate Data Revision
Consolidate Year 11 univariate data skills: calculate mean, median, mode, range and standard deviation, read dot plots and histograms, and interpret data spread — preparation for scatterplot, correlation and regression lessons.
Lesson 2
Bivariate Data and Scatterplots
Interpret bivariate data, scatterplots, association direction, strength, outliers, and causation warnings.
Lesson 3
Correlation and Association
Describe direction and strength of linear association using scatterplots and correlation values, while avoiding causation claims.
Lesson 4
Regression Equations, Predictions and Residuals
Use regression equations to make predictions, interpret slope, and calculate residuals as actual minus predicted values.
