Question

Quizplus · Accepted Answer

An interrupted time-series design is a type of quasi-experimental design that is often used in applied research. This design is particularly useful when it is not feasible or ethical to conduct a randomized controlled trial (RCT), but we still want to evaluate the impact of an intervention or policy change. In an interrupted time-series design, we first collect data on a particular outcome variable for a period of time before the intervention or policy change (the baseline period), and then we collect data for a period of time after the intervention or policy change has been implemented (the intervention period). By comparing the trend in the outcome variable before and after the intervention, we can get an estimate of the intervention's causal effect.
