How does a time series design with nonequivalent control group differ from a nonequivalent control group design? Identify a threat to internal validity that is controlled by adding a nonequivalent control group to a simple interrupted time series design.
What will be an ideal response?
The time series design with nonequivalent control group differs from a nonequivalent control group design because in the time series design there are multiple observations before and after the time the treatment is administered. Many potential threats to internal validity due to history (events that occur at the same time as treatment) are controlled by adding a nonequivalent control group to a simple interrupted time series design.
