View the anxiety data (Sport Competitive Anxiety Test – SCAT) collected from a group of middle-distance runners. All the runners completed the questionnaire before being split into either a control group (who received no imagery intervention) or an experimental group (who received an imagery intervention). The anxiety scores were then measured again after 6 weeks. If we wanted to compare the control group results with the experimental group results, what type of research design would we use?
