A time series with nonequivalent control group design would allow the researcher to compare the recycling rates before and after the program was implemented in the intervention group (the community where the program was implemented) and the control group (a similar community where the program was not implemented). This would help to determine whether the program was effective in increasing recycling rates in the intervention group compared to the control group.
