A researcher at an alcohol treatment center conducted a client satisfaction survey on Treatment methods A, B and C. The researcher divided 10 clients into 3 groups. Four (4) clients received Treatment A, three (3) clients received Treatment B and three (3) more clients received Treatment C. Two weeks later, client satisfaction levels were measured. The mean satisfaction for the treatment was 10 for Treatment A, 6 for Treatment B and 4 for Treatment C. Table 2 summarizes the results of the analysis of variance for the study.
