Course Description

Who Should Be Taking This Course? STAT 112 is a required course for students planning to enroll in the McIntire School of Commerce. If you want to take a statistics course only to satisfy the College's natural science requirement then you should consider taking STAT 110 rather than STAT 112. Students interested in the Minor in Statistics and Data Analysis should take either STAT 500 or APMA 312 or MATH 312. STAT 112 cannot be used to meet requirements for the mathematics major. The appropriate statistics course for mathematics majors is Math 312.

Prerequisites: The only prerequisite for STAT 112 is High School Algebra 2. However, some students may find it useful to take MATH 111 (Probability) before taking STAT 112. It is worth noting that entry to the Commerce School requires, in addition to STAT 112, either Math 111 or Math 121. So students opting for Math 111 would normally want to take that course before STAT 112.

Textbook

The textbook for this course is Introduction to the Practice of Statistics, fourth ed., by D. Moore and G. McCabe, published by W. H. Freeman & Co. The course covers material from chapters 1, 2, 3, 4, 5, 6, 7, 8, and 10. See the course syllabus for more details.

Computer Work

Minitab, a statistical computing package with a menu-driven interface, is used in the course. The Minitab program is available on Macs and PCs in all the ITC Public Computing labs throughout the University. Because of license restrictions, ITC does not provide copies of Minitab for use on private computers. Minitab can be downloaded for a 30-day free trial, rented for 5 months, or purchased from the e-academy's website at http://www.e-academy.com/minitab.

The following are helpful : Brief Minitab User Guide and Using Minitab: A Short Guide Via Examples.

The first guide is intended for quick reference. The second guide provides lots of details, including screenshots, and is very helpful for learning to use the package.

Computer Help Sessions: Optional weekly computer help sessions start on Monday, September 1st and are held according to the following schedule:

Monday: 7:00 - 8:00 pm, MEC 216
Monday: 8:00 - 9:00 pm, MEC 216
Tuesday: 7:00 - 8:00 pm, MEC 216
Tuesday: 8:00 - 9:00 pm, MEC 216

You are encouraged to read relevant sections in the computer help guides described above before coming to the sessions. You are welcome to come to the computer help sessions with any course material or homework questions, however, the MINITAB questions will be given priority.

Data for Solving Problems Using Minitab: You can download data sets corresponding to various exercises and tables of the textbook by clicking on DATA. This data also appears on the CD that comes with the textbook.

Homework Assignments

Each week's homework assignment is collected on Wednesday of the following week at the BEGINNING OF THE CLASS (with the exception of homework assignment #13 that will be collected at the beginning of Monday's class, on December 1st). Refer to the syllabus for homework assignments. Each homework set is spot-graded for up to 10 points (up to 2 points for each of two randomly selected problems, and up to 6 points for overall effort).

Solutions to the homework problems are posted on the Toolkit Stat 112-1 and Stat 112-2 websites in Materials by 5:00 pm on the day the homework assignment was collected.

Suggestions Regarding Homework Assignments:

DO NOT WAIT UNTIL THE WEEKEND TO START THE HOMEWORK PROBLEMS. After each Wednesday's class a sufficient part of the material will have been covered to work the next homework assignment, and you should begin. Please read the homework material and have your questions ready before you go to your recitation section or a computer help session. With the exception of the classes just before the exams, there will be NO DISCUSSION OF THE CURRENT HOMEWORK ASSIGNMENT on Mondays.
