  1. There is a significant difference between groups that are not connected by the same letter. For example, the three groups of 0–9, 10–99, and 100–999 are connected by A because there is no significant difference between them. On the other hand, the group of 1000–9999 is connected by B instead of A because there is no significant difference between the three groups of 0–9, 10–99 and 1000–9999 but there is a significant difference between the 100–999 group and the 1000–9999 group
