Are appropriate for comparing the incidence of hypertension in two groups Incorrect answer selected
Are less powerful than non-parametric tests Correct
Give the results as odds ratios Correct
Include the analysis of variance Correct
Require the data to have a normal distribution Correct
Explanation
The incidence of hypertension, that is, did/did not occur, would be categorical (or qualitative) data thus requiring a non-parametric test (that is, chi square test).
They are more powerful than non-parametric tests, that is, they are more likely to show a difference that really exists.
Parametric tests give p values and not odds ratios.
Analysis of variance (ANOVA) is used to test multiple groups of parametric data.
Parametric tests require the data to have a normal distribution, whereas non-parametric tests could be used for normal and non-normal data.
