ANOVA for language skills in SPSS

Solve for the following problem as well as write the results and present it as well as you would do for publication. Present any revelant data in SPSS.

First-born children tend to develop language skills faster than their younger siblings. One possible explanation for this phenomenon is that first-borns have undivided attention from their parents. If this explantion is correct, the it is also reasonable that twins should show slower language development than single children and that triplets should be even slower. Davis (1937) found exactly this result. The following hypothetical data demonstrate the relationship. The dependent variable is a measure of language skill at age 3 for each child. Do the data indicate any significant differences. Test with α= .05.
