The study discussed the application of multiple comparison methods in enhancing decision making in statistical inference. The study designed an experiment on sales of rice using the population of rice brands as the treatment. Few samples were examined and their sales volume were examined for eight weeks at a rice dealing business enterprise. Using the Tukey, Dunnett and the Fishers LSD multiple comparisons’ approach, the study measures the preference of the of rice brands. Using the One-Way ANOVA the report indicated that there was a difference in the sales volume for at least one type of the rice brands. The result also indicated that from the multiple comparisons’ result above the Mama Gold rice brand had more sales volume. In addition, the Tukey’s method reported an individual confidence level is 99.53, the Fisher’s method indicates an individual confidence level of 63.03 and the Dunnett’s method reported a 95% individual confidence and this implies that of all the three methods used for the multiple comparison of means, the Tukey’s method proved to be more adequate in estimating the comparison of means....
