stratified - occurs with specific strata
experiemental comparison analysis
t tests
man-whitney u.test
chi squared
relative risk and odds ratio
Quasi experimental comparison analysis
no random assignment or intervention
indepdndent variable is only partially under researcher control
examines cause and effect by ruling out plausible alternative explanations
Causal comparative studies
