Objective
The purpose of the course is to train students to formulate analytical problems,
to survey statistical techniques, and to introduce technical concepts from the core departments of Stem. The course
stresses applications, the technical aspects underlying the methods will be presented intuitively.
The computer will be used as a tool for problem solving. No computer programming
background is necessary and detailed instruction for the computer package MINITAB (Version 11) will be provided.
This program is available to students in the computer labs.
The mathematical prerequisite for the course is the equivalent of A63.0017. This
includes a review of elementary algebra and analytical geometry, and the applications of differential calculus
to business problems.
The course will be taught in lecture and discussion mode. Student participation
is strongly urged.
There will be 3 seventy-five minute lectures each week. There will be a TA for
the course and she will hold regular office hours. The schedule will be announced in class.
Homework Assignments
Assignments will be given out each week and must be submitted the following week
for review. All assignments must be completed. There will be a group project, details of which will be given in
class.
