This individual framework pack gives you one
complete, focused topic framework for your
IB Math AA Internal Assessment.
THE FRAMEWORK: Data Distribution Analysis
This framework guides you through a statistical
investigation of how data from a real-world
source is distributed — using descriptive
statistics, the normal distribution, and
statistical reasoning to draw meaningful
and well-supported conclusions.
MATHEMATICAL CONCEPTS:
✓ Descriptive statistics (mean, median,
standard deviation, IQR)
✓ Normal distribution and standardization
✓ Cumulative frequency and box plots
✓ Z-scores and probability from the normal
✓ Comparing two distributions
SL APPROACH:
Collect or source a real data set, analyse its
distribution using descriptive statistics and
the normal distribution, and draw conclusions
about what the distribution reveals about
the real-world context.
HL APPROACH:
Extend to hypothesis testing (z-test or t-test)
to compare two populations, or investigate
whether the normal distribution is an
appropriate model for your data using
chi-squared goodness of fit.
PERSONALIZATION OPTIONS:
