If the studies are inconsistent, it means that at least some of the age group from the first study will not be included in the second study, or some of the age group from the second study will not be in the first study. Therefore, to determine if the two studies are inconsistent in their description of generation A we must compare the age groups from the two studies to see if either one includes people not included in the other study. In other words, we need to determine if the age ranges match up exactly when the year of the study is taken in to consideration. In the first study from 2005, generation A is defined to be people ages 19-30. Three years later, in 2008, the second study was published and defined generation A to be people ages ages 22-33. First we examine the low end of the age ranges. We note that someone who was 19 years old in 2005 would be years old in 2008. Now we examine the high end of the age ranges. We note that someone who was 30 years old in 2005 would be years old in 2008. The low and high
