Introducing Scatter Plots


In this chapter, we’ll examine athletic graduation rates for a group of uni-
versities. The Big Ten workbook contains information on graduation rates
of student athletes (with athletic scholarships) who enrolled as freshmen at
Big Ten universities in 1997, 1998, 1999, and 2000. Each NCAA Division I
college or university is required to distribute this information to prospective
student-athletes and parents, so that potential recruits have a way of com-
paring the education environment between different universities. Table 3-3
describes the range names used in the workbook.

To open the Big Ten workbook:

1 Start Excel and open the Big Ten workbook from the Chapter03
folder.
The workbook opens to a sheet displaying graduation data from the
11 universities in the Big Ten. See Figure 3-3. Range names based
on the column labels of each column have already been created for
you. There are some missing values in the worksheet, such as the
SAT value for the University of Iowa in row 4. However for univer-
sities that do not collect SATs, a calculated estimate of the SAT is
displayed in column E.
