Quizplus · Accepted Answer

Jake used a time series design where he collected data for the same variable (crime rates) at regular intervals before and after the implementation of a new street lighting program. This design allows for the analysis of changes over time and is appropriate for studying the impact of interventions or events that occur at a specific point in time. The other designs listed may not be appropriate for this study, as they involve different types of comparison or manipulation of variables.
