Interrupted Time Series Design Examines the dependent variable over an extended period of time,

both before and after the IV is implemented Interpretation problems (possible regression to the mean)

QUASI-EXPERIMENTAL QUASI-EXPERIMENTAL DESIGNSDESIGNS

Control Series Design Improves interrupted time series design by finding an

appropriate “control group” Involves finding a similar population that did not receive a

particular manipulation Limited because this is not a true “control group”

DEVELOPMENTAL RESEARCH DEVELOPMENTAL RESEARCH DESIGNSDESIGNS

Cross-Sectional Method – persons of different ages measured at the same point in time

Longitudinal Method – same group is observed at different times (as they age)
