Feedback and error review.

Try this with General Mathematics

1. Choose one criterion, teacher comment or mark you want to understand.
2. Compare your answer against that criterion and rewrite only the part that missed it.
3. Try the same skill on a fresh task to see whether you can apply the feedback.

• Scatter plots, explanatory and response variables and the statistical investigation process
• Pearson's r and r²: direction, strength, outliers and causality
• Least squares linear regression: interpreting slope and intercept in context
• Residual plots and choosing between linear and exponential models
• Exponential regression, interpolation, extrapolation and reliability of predictions
• The normal distribution: parameters, bell shape and the 68:95:99.7% rule
