Hypothetical data demonstrate the relationship

Reference no: EM1390835

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 explanation is correct, then it also reasonable that twins should show slower language development than single children and that triplets should be even slower. Davis 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=0.05.
