A Psychologist was interested in the variation of ability to cope with workplace-related stress (CWWS score) across four groups with different physical activity levels. He ran an ANOVA with the predictor variable 'group', which had four categories, 'sedentary', 'low', 'moderate', and 'high' levels. The outcome variable was 'coping_stress'.
