introduces a study investigating whether a brief diet intervention might improve depression symptoms. In the study, 75 college-age students with elevated depression symptoms and relatively poordiet habits were randomly assigned to either a healthy diet group or a control group. Depression levels were measured at thebeginning of the experiment and then again three weeks later. The response variable is the reduction in depression level (as measuredby the DASS survey) at the end of the three weeks. Larger numbers mean more improvement in depression symptoms. Test whetherthese experimental results allow us to conclude that, on average, improvement of depression symptoms is higher for those who eat ahealthy diet for three weeks than for those who don't. The data is available on StatKey and in DietDepression.
