Analysis - Phase 2

Finally, the data was analyzed in accordance with hypothesis 2 (regional). The regional analysis used the ANOVA and T tests. The ANOVA test revealed that the p-value was less than 0.05%, showing that the data does not have a normal distribution and does not have equal variance. Therefore, we could not perform the Tukey test. The ANOVA Test concluded that of the 4 regions, one is different than the rest. Next, we grouped the regions into the following pairs: Northeast vs Midwest, Northeast vs South, Northeast vs West, West vs South and Midwest vs West. A Pairwise T test was used to compare the groups’ mean values. The Pairwise T test revealed that the Northeast region is different from each region in the group.
