01 / QUICK RECAP
Connect the ideas.
- Choose centre and spread for the question; state units and identify grouped estimates.
- Order data and state the quartile convention before finding a five-number summary.
- Compare box plots on a common scale; IQR describes the central half, not the whole range.
- State percentile conventions and interpolation assumptions.
- Distinguish population from sample standard deviation and choose the right denominator.
- Preserve paired observations; describe direction, strength and form without inventing causation.
- Use the conditioning group's total for two-way-table percentages.
- Report sampling, measurement and presentation limitations alongside a supported conclusion.
