In ANOVA, Total SS is related to the total sum and explained sum with the following formula: Total SS = Explained SS + Residual Sum of Squares. The sum of squares can also be used to calculate other statistical measures, such as thecoefficient of determinationand themean squared error. ...
Comparisons between groups performed in ANOVA using post-hoc tests showed significant differences, with emphasis on the total score of pharmacists who carry out professional activities in outpatient clinics compared to hospital pharmacists or those working in public pharmacies. Table6presents data referring...
