Scatter Graphs & Correlation
Mathematics · Data & Statistics · conceptual
Describe simple mathematical relationships between two variables using scatter graphs, identify positive, negative, or no correlation, and use a line of best fit to make predictions
What mastery looks like
- Plot bivariate data on a scatter graph and describe the type of correlation observed
- Draw a line of best fit by eye and use it to estimate a value within the data range
- Explain what positive, negative, and no correlation mean in the context of real data (e.g., temperature vs. ice-cream sales)
Check your understanding
If Scatter Graphs & Correlation plotted a scatter graph — say, comparing hours of revision and test scores — could they draw a line of best fit, describe the pattern, and use it to make a prediction?
