^∗Group value is a general form of the contrast analysis, so if it is not found significant, the post hoc values of that column will not be significant either. Therefore, the post hoc values were not shown in the table. ^∗∗Due to space limitations, the F-values and corresponding statistics of vehicle colors are not shown in the table.
