Lesson 1
6A Constructing a Scatterplot
Distinguish univariate and bivariate data, identify independent and dependent variables, create scatter plots, and describe associations by form, strength and direction.
Lesson 2
6B Using a Scatterplot
Describe association by direction, form and strength, identify outliers, and distinguish correlation from causation.
Lesson 3
6C Line of Best Fit
Draw a line of best fit by eye, find its gradient and y-intercept, and use interpolation and extrapolation to make predictions.
Lesson 4
6D Interpolation and Extrapolation
Predict from a line of best fit and judge reliability by interpolation within the data versus extrapolation beyond it.
Lesson 5
6E Statistical Investigation
Interpret graphs, tables, averages and spread measures in practical contexts.
Lesson 6
Probability and Chance (folded)
Use probability language, tables, and simple chance models to solve practical problems.
Lesson 7
Relative Frequency and Expected Value (folded)
Use complementary events P(not A) = 1 − P(A), estimate probability from relative frequency, and calculate expected frequency np.
