MTH 150 C -- Elementary Statistics
  Fall 2009

Final Exam Information:
The final will be Tuesday 12/16/09 from 1 to 4 in SLC 101. 
You may bring the foldout table card from your text and a calculator.  You will also be allowed to bring in four pages of notes (8.5" by 11").
This page count includes your copy of the hypothesis test summary sheet -- i.e. the two page summary sheet plus two other pages equals your total of four pages.. 

The final is cumulative and will cover topics discussed during the semester from Chapters 1 through 11.  Old exams should be your best guide to topics to be covered.  The final will be structured much like the last exam: several pages of short answer, true-false, etc. questions and then five or so pages of major problems to work out -- hypothesis tests, regression, confidence interval computation, probability computation, etc. with a chance to choose only one problem per page for those last pages.

Course Description and Objectives:   Elementary statisitcal inference, with an emphasis on ideas, techniques, and applications in the life, physical, and social sciences.  Topics include descriptive statistics, confidence intervals, hypothesis testing, contingency tables, multiple regression, and analysis of variance.  A significant portion of the research done in the biological, health, and social sciences depends to a large extent on statistical studies in general and statistical inference in particular.  Appropriate statistical use is also a major tool in other disciplines as well.  It is probably fair to say that no mathematical tool (excluding basic arithmetic) is used more heavily than statistics.  Therefore the overriding objective of the course is to learn how to draw an inference based on a statistical study, and to be able to measure how 'good' that inference is.  Students successfully completing this course should:
Prerequisites: Student must have completed MTH 94 or have two years of high school algebra.  Not open to mathematics majors or students with credit in MTH 351.    

Calculators and Computer Accounts:  You will need a calculator.  You should bring your calculator to each class (along with your textbook and the notebook in which you are keeping your homework).  A TI-84 will be used for in class demonstrations.  If you already have another calculator it can probably be used, but we will not spend class time trying to figure out how to do what we are doing on the TI-84 on your calculator.  I will be happy to help with that outside of class -- if you bring the instruction book!  Email is the best way to communicate with me and there will be important class information on these web pages.  You will need access to email and the web, either through  your Wilkes University account or another account of your choice. There will be two computer projects using the software StatDisk on the CD packaged with your text book.  The most up-to-date version of this software is also available on the web at or at .

Attendance:  You are expected to attend all classes. You are responsible for everything that goes on in class (even if you are not there).  Roll will be taken at each class.  In accordance with university policy, four or more unexcused absences will result in an F in the course.

Exams, Homework and Computer Project Grades:  There will be four full period exams (tentatively scheduled for 9/25, 10/23, 11/13 and 12/9) the best three of which will each count for 1/6 of your grade.  You will be permitted to bring one 8.5 in. by 11 in. sheet of paper with notes to each hour exam, and two such sheets to the final exam.  There is a detachable formula/table card in your text that you may also bring to exams. It is your responsibility to bring the card, your caclulator, etc. to exams -- there are no extras available.   There will be two take-home computer projects during the semester and I will pick up homework assignments about ten times during the semester, about once a week, at the end of class, following the schedule shown on the assignment page.  Your best seven homework grades will be added to the two computer project grades and will together count for 1/6 of your grade.   There will be a final exam, given during finals week, which will count for 1/3 of your grade.    No makeups will be given for exams, if you miss one it will be one you drop.  Homework and computer projects will not be accepted late.  If classes are canceled or put on a compressed schedule due to the weather on an exam day, the exam will be given at the next regular class.

Homework Assignments:  Homework assignments will be made at every class.  You need to do them promptly -- completing the homework will help you understand the issues that come up in class.  In order to encourage you to do your homework, the homework assignments will be collected and graded.  There will sometimes be time in class to ask questions about the homework, and if this is not enough time you should see me outside of class to get your questions answered.  You may also email me with homework questions -- include a statement of the problem since I will not always have my book with me when I am checking my email.  Your homework will be given a grade of up to 10 points, 4 'effort' points -- based on my assessment of the number of problems have been attempted and the level of effort shown.  Three of the problems in each assignment will be graded for correctness -- for up to 2 points each.  In general I expect to see your work and/or explainations, not just a list of answers. A list of all the assignments can be found on the assignment page.  It will be updated as the semester progresses.  There will also be two special computer projects worth 15 points each.

Academic Honesty:  The work you hand in should be your own work.  If there is evidence that work you hand in is not your own, the first time you will receive a zero on the exam and the second time you will receive an F in the course.  Appropriate deans will also be notified.

Drop Policy:  If you wish to drop, I will give my permission during the first ten weeks of the semester.  Thereafter you will need the permission of the Dean.  Be aware that poor performance in the course will not be sufficient reason for the Dean's permission to be granted.

Grading:  The total points available are computed as follows:
best 3 of the 4 inclass exams  @ 100 pts. ea. 300
best 7 HW grades @ 10 pts ea.
two computer projects @ 15 pts. ea.
final exam 200
total possible points 600

and your final grade will be computed from the total points you earn as follows:
Total Points 0 to 359 360 to 389 390 to 419 420 to 449 450 to 479 480 to 509 510 to 539 540 to 600
Grade 0 1.0 1.5 2.0 2.5 3.0 3.5 4.0
