This individual framework pack gives you one
complete, focused topic framework for your
IB Math AA Internal Assessment.
THE FRAMEWORK: Correlation and Relationships
This framework guides you through a statistical
investigation of the relationship between two
measurable variables using correlation analysis
and linear regression — applied to a real-world
data set that you collect or source.
MATHEMATICAL CONCEPTS:
✓ Pearson’s correlation coefficient
✓ Linear regression (line of best fit)
✓ Scatter plots and data visualization
✓ Interpretation of correlation strength
✓ Limitations of correlation vs causation
SL APPROACH:
Collect or source bivariate data, calculate and
interpret the Pearson correlation coefficient,
and fit a regression line. Discuss the strength
and limitations of the relationship.
HL APPROACH:
Extend to non-linear regression, hypothesis
testing for correlation, or Spearman’s rank
correlation for comparison. Add greater depth
in statistical interpretation and critical evaluation.
PERSONALIZATION OPTIONS:
□ Academic performance vs lifestyle factor
□ Temperature vs energy consumption
□ Training hours vs athletic performance
□ Social media usage vs study hours
□ Economic indicator relationships
□ Any two measurable variables of your choice
