Choosing statistical tests
This table is one that I think every public health student should be able to generate after taking statistics. Unfortunately it is not presented this way
| Dependent/outcome | |||
| Independent/predictor | Dichotomous | Categorical | Continuous |
| Dichotomous | Chi-square | Chi-square | t-test |
| Categorical | Chi-square | Chi-square | ANOVA |
| Continuous | Logistic regression | ??? | Correlation or regression |
Caveat: This ignores study design. In real analyses it is common to adjust for covariates, use repeated measures or do something else that requires different tests. Nevertheless, it shows the basic test underlying what you will use.
