Quizplus · Accepted Answer

The research design is a time series because it involves collecting data over time (before and after the development controls were in place) to determine if there was a change in the number of new building permits issued. A true experiment would involve randomly assigning participants to experimental and control groups and manipulating an independent variable, which is not the case here. Noncomparable groups and cross-sectional research designs also do not fit this study.
