The Maths Education Study Your colleague is conducting an intervention to help alleviate anxiety around mathematics. They collect a sample of students with different educational backgrounds; those who exited high school before year 12; those who completed a maths course in year 12, and; those who completed any level of tertiary education that involves some amount of mathematics. Your colleague measures their anxiety toward maths prior to the intervention (Week 1), and then they all engage in a targeted anxiety-reducing maths intervention. Anxiety is measured again at the conclusion of the intervention (Week 2). Question: Looking at the output below, what might you readily conclude?
