We assume that our wages will increase as we gain experience and become more valuable to our employers. Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the picture. How does length of service (LOS) relate to wages? The data here (data393.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the...
