The time series design with control group involves collecting data before, during, and after the training program for both the experimental group (who receives the training) and the control group (who does not receive the training but is otherwise similar). This allows for comparison over time between the two groups and helps to control for external factors that may influence the results. This design therefore offers the strongest conclusions on the effectiveness of the training program.
