She randomly selected 24 students and then randomly divided this group into three subgroups: a 'Placebo' group who did a maths test in their usual classroom environment; an 'Outdoor' group who did a maths test in an outdoor setting within the school grounds; and a 'Chill out' group who did a maths test in a 'chill out' space within the school, that had dimmed lighting, music and casual seating. The children spent one hour within their settings and their maths scores were recorded at the end of the test. What sort of research design is this?
