Exploring relationships between variables on the Isle of Fastmoney The data in the file iofm.xls is from a random sample of 100 people on an (imaginary) island. Sexn is a numerical coding for sex, run 10km is each persons time in minutes in a 10km race, cycle 10km is their time in a cycle race, and earn000E is their earnings in thousands of euros. What relationships can you find between the variables? Are they all what you would expect? (Well return to this example in Chapter 9.)
