Practice one-way ANOVA analysis from start to finish using real public health data

A one-way analysis of variance (ANOVA) was used to compare mean days of poor mental health across three physical-activity groups defined from survey responses: individuals reporting no regular activity, those engaging in moderate-intensity activity, and those engaging in vigorous-intensity activity. The analysis tested whether between-group differences in means exceeded within-group variability using the F-statistic, under assumptions of independent observations, approximately normally distributed residuals, and homogeneity of variances.
