In the book, we will focus on one major research project for Accu-Phi. Accu-Phi has
now been selling services to the pilot group for over a year. Some 279 customers have
bought services from the pilot territory. Among this group, you are interested in
explaining and even predicting first year services sales in dollars, largely because
as a business you want to maximize sales.
Based on your studies or business background, you have used theory and experience
to choose other things that you think might explain, predict or at least associate
with sales. The next sections discuss these.
