Check understanding

• 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)

“If your child 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?”
