O REGRESSION AND CORRELATION
Computing the sample correlation coefficient and the coefficien.
In ongoing economic analyses, the federal government compares per
capita incomes not only among different states but also for the same
state at different times. Typically, what the federal government finds is
that "poor" states tend to stay poor and "wealthy" states tend to stay
wealthy.
Would we have gotten information about the 1999 per capita income for a
state (denoted by y) from its 1980 per capita income (denoted by x)? The O
following bivariate data give the per capita income (in thousands of
dollars) for a sample of fourteen states in the years 1980 and 1999 (source!
U.S. Bureau of Economic Analysis, Survey of Current Business, May 2000).
The data are plotted in the scatter plot in Figure 1. Also given are the
products of the 1980 per capita incomes and 1999 per capita incomes for
each of the fourteen states. (These products, written in the column
labelled "xy," may aid in calculations.)
