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)
