Odds Ratio for Retrospective Analysis:

Use the results of a retrospective study to determine if there is a positive association between smoking and lung cancer, and to (through mathematical manipulations) estimate the risk of lung cancer for smokers relative to non-smokers.  Key ideas:  Conditional Probability, Odds, Retrospective Observational Study.

JMP features demonstrated:

Analyze > Fit Y by X, the Value Ordering column property

Statistical/graphical tools used:

Mosaic plots, two-by-two contingency tables, odds ratios and confidence intervals for odds ratios, hypothesis tests for proportions (likelihood ratio, Pearson's, Fisher's Exact, two sample tests for proportions).
