ex0525: IQ and Future Income
Description
These data are annual incomes in 2005 of a random sample of 2,584 Americans
who were selected for the National Longitudinal Survey of Youth in 1979 and
who had paying jobs in 2005. The data set also includes a code for the number
of years of education that each individual had completed by 2006: <12, 12,="" 13--15,="" 16,="" and="">16. How strong is the evidence that at least one of the five
population distributions (corresponding to the different years of education)
is different from the others? By how many dollars or by what percent does the
mean or median for each of the last four categories exceed that of the next
lowest category?source
