Recode age into three groups 118 to 39 = 12140 to 59 = 22160 and above = 32 by using Transform then Recode into Different Variables and naming the new variable AGEGRP3 (for age grouped in three categories). Actually, the new name is up to you, but this name is fairly clear. Recalculate chi-square from the problem above. What is the level of measurement for grouped age? Apply a chi-square statistic to test the null hypothesis that attitudes toward abortion for any reason (ABANY) do not vary by grouped age (AGEGRP3).
