Thank you for sharing this great information. ANOVA analyses seek to determine relationships between factor levels (treatment differences of independent variables) and against the dependent variable (Gravetter et al., 2021). The concept of coffee admissions and noise level on cognitive work is interesting and could be applicable to a wide range of working adults today. What method of measurement would you recommend for cognitive work? Would your population sample be a specific workforce, or a random sampling of workers? Thanks for sharing!
