Course Objectives:

Statistics is a discipline that supports research and development; its methods help scientists and engineers answer questions in the face of variability. In STT 351 students are exposed to models and methods that are used in engineering disciplines, applied research and industry. Continuous themes are the importance of quality data, the careful use of terms, and the clear presentation of statistical information and analyses. Students will use some computational software package such as Minitab.
The student shall be able to
  1. describe and present data and information using summary statistics, tables and graphical displays.
  2. use probability in modeling experimental outcomes and assessing uncertainty.
  3. select and use probability models (from Binomial, Normal, etc.) for the variation present in a selection of engineering applications.
  4. use data generated by random sampling to make inferences about the parent population or stable process using confidence interval and hypothesis testing methods and check the appropriateness of the methods.
  5. examine relationships among variables using regression techniques and check the appropriateness of the models.
  6. apply statistical process control charts and techniques to determine the stability of a process and perform analyses on measurement processes so as to understand and control variability and biases introduced by measurement.

Course Outline:

Time permitting we will choose from a number of special topics such as The approximate coverage of the basic probability and statistics concepts as outlined in the course objectives above are as follows.
Topics Book Chapters Approx. Time for Coverage
Obtaining and interpreting data  Chap. 1  1 week
Probability concepts Chap. 2 1 week 
Probability models Chap. 3, 4 and 5 4 weeks 
Statistical inference Chap. 6, 7, 8 and 9 5 weeks 
Regression  Chap. 12 1 week 
ANOVA and Quality Control etc.  Chap. 10 and 16 2 weeks 


Projects (optional):

Two projects are collected for grading (at 25 points each). All answers and steps must be clearly explained for the projects to be considered for grading. The problems involve using the statistical software package Minitab. You are encouraged to discuss project problems with other students. It is allowed that you submit the project as a group (max. 3 students). No late projects will be accepted. For the project format please check out http://www.stt.msu.edu/~pathakp/stt351spring/project.html


Homework:

Reading and homework problems  will be assigned regularly in the lecture. Many problems are from the book, and some will be assigned on handouts. Some of the problems involve using the statistical software package Minitab. You are encouraged to discuss homework problems with other students. Homework is not graded. Quiz problems are often taken from the homework problems.


Quizzes:

There will be five 30-minute quizzes (20 points each) scheduled for :
Jan 26, Feb 9, Mar 2, Mar 23, Apr 20.
 The quizzes are used to practice the material taught in the lecture and help you to develop
problem-solving skills. The quizzes will be based on homework problems. There are no Make-ups. For the purposes of computing the final grade, the  lowest quiz score will be dropped.
You can look up your quiz socre in the following file.http://www.stt.msu.edu/~pathakp/stt351spring/q135105.htm


Exams:

There will be two exams, and a final exam. The exams are closed book, but hand calculators are permitted with the exception of the TI-92. You should be able to compute two-variable statistics on your calculator (e.g. compute mean, standard deviation, correlation coefficient from keyed-in data). This saves a lot of time on homework and exams.
If a student misses one exam s/he will be graded on the basis of the other work provided that s/he has an ironclad excuse, and s/he contacts the instructor on or before the day of the exam to arrange a conference. In this case the part of the final exam that covers the material on the missed exam will count towards the missed exam grade.

Other important Dates:

The calendar containing exam and quiz schedule can be found http://www.stt.msu.edu/~pathakp/stt351spring/cal.html

Grading:

Grades will be based on a straight scale generated from points accumulated during the semester (see the Gradeworksheet http://www.stt.msu.edu/~pathakp/stt351spring/grade.htm ). The breakdown of possible points is shown below.
Exam 1 80 points
Exam 2 80 points
Final Exam 160 points
Quizzes 80  points
Total 400 points

Your final grade is computed as follows. This should be viewed as a TENTATIVE scale which may be modified over the term.

4.0
3.5
3.0

Advice:

Read the assigned material before the lecture and again after the lecture. Do the homework problems, there are many unassigned problems in the text that provide good practice. Do not fall behind! At the beginning of most class periods we will go over questions about the homework problems. Check frequently the 351 Home Page on the Web for the latest news!

The instructor reserves the right to make any changes she considers academically advisable. Changes will be announced in class, it is your responsibility to keep up with any changed policies.
