Numerical Summary
(b) To numerically compare the two groups, calculate (by hand) the conditional proportion who yawned in each group and the observed difference as follows:Of the 34 subjects in the Seeded group, what proportion of these subjects yawned?
Of the 16 subjects in the Control (no yawn seed) group, what proportion of these subjects yawned?
Calculate the difference in these conditional proportions:
Seeded Group Proportion - Control Group Proportion Difference
Side note: It's actually easier to interpret this difference in terms of proportions rather than percentages. If you convert to percentages, it's too easy for example to say "the difference was 10%" when you really mean "10 percentage points." A "difference of 10%" implies multiplication, not subtraction.
