Bivariate scatterplots and association
Students construct scatterplots to identify and describe associations between two numerical variables. They calculate and interpret the correlation coefficient to measure the strength of linear relationships.
About This Topic
Students construct scatterplots to identify and describe associations between two numerical variables. They calculate and interpret the correlation coefficient to measure the strength of linear relationships.
Key Questions
- How do we visually represent the relationship between two variables?
- What does the correlation coefficient tell us?
- How can we identify outliers in a scatterplot?

Planning templates for General Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

Linear regression and modelling
Students fit a least-squares regression line to bivariate data and interpret the intercept and slope. They use the regression line to make predictions and analyse residual plots to check the model's validity.

Time series analysis
Students explore time series data to identify trends, seasonality, and irregular fluctuations. They apply smoothing techniques to reveal underlying trends and make forecasts.
