Math 201, Introductory Statistics

Instructor Information

Eric Schulz, Office #288A, 509-527-4281, eric@wwcc.edu. My office hour is posted as 9:30 to 10:20 daily. I'm available at other times during the day to help students be successful in my courses. Feel free to contact me via email or phone to schedule an appointment outside of my office hours. I normally respond to email promptly during the day but rarely in the evenings and on weekends. If you send an email in the evenings or weekends I will reply as soon as I can on the following work day.

Course Description

A study of both descriptive and inferential statistics. Topics for the course include: data presentation, and analysis, measures of central tendency and dispersion, sampling distributions, parameter estimation/confidence intervals, hypothesis testing, and linear regression. Prerequisite: Grade of "C-" or higher in MATH 95 or permission of the Mathematics Department.

Required Materials

- The textbook for the course is
*The Basic Practice of Statistics*, 3rd edition, by David S. Moore, W.H. Freeman. ISBN - 0716796236 (Hardcover) or 0716702231 (Paperback). - A scientific calculator capable of two variable statistics calculations.
- iSolve access code for online homework submission (see information below). The ESTAT bundle is highly recommended and is included with new textbooks. ESTAT/iSolve can be purchased separately if you have purchased a used textbook.

Attendance

Attendance at every class session is expected. I understand absences
are sometimes unavoidable and will work with students when such occasioins arise.
In the event of an absence occuring on the date of a scheduled exam or quiz,
**prior** arrangments must be made in order to schedule another
time to write the exam.

Homework Problems: Textbook and iSolve

Problems from the textbook will be assigned and discussed regularly. Complete solutions for the assigned textbook problems will be available via the course website. The purpose of the assigned homework problems is to provide an opportunity for students to learn and master the course content and thereby increase the probability of successfully completing the course. If homework is not done regularly and diligently, the probability of completing the course successfully will be very small.

The work done on completing the textbook assignments will not be turned in to, nor graded by, the instructor. Understanding and mastery of assigned homework will be measured using the online iSolve software supported by the publisher of our textbook. The chapter assignments to be completed in iSolve are composed of the same problems that are assigned in the textbook (or a subset thereof). It is recommended the students complete the textbook assignment before logging in to iSolve to complete the online assignment for a grade - this will minimize the time required to be sitting in front of a computer. If the textbook problems have been completed and understood before logging in to iSolve, then answering the online questions and submitting them for a grade should not take a long time.

The chapter assignments in iSolve can be completed and submitted for a grade at most TWICE. A passing grade on a homework assignment is any score that is greater than or equal to 80%. Once an assignment has been submitted for a grade iSolve will provide comments on incorrect results so that students can then learn from their mistakes and try the assignment again.

If a student does not have time to complete an assignment after logging in to iSolve, it is possible to Quit and Save current work. Work on the assignment can be continued at a later time.

The online iSolve assignments can be completed any time up to
9:00 pm on the day the assignment is listed as being due on the class quarter
schedule (where you will also find convenient links to iSolve). **DO
NOT PROCRASTINATE!!** There are no exceptions to the listed due dates.
The online assignment due dates have been set to allow students plenty of time
to complete the assignment after the material is covered in the course (see
the quarter schedule).

ESTAT Pack

The publisher has developed a 4 CD supplement for our text called "ESTAT". ESTAT includes a very rich set of tutorial materials covering the content of the course - it should be of benefit to students who would like extra input beyond reading the text and attending class.

Web Resources

The course website can be reached from a link at http://math.wwcc.edu/eric/
. A dynamic quarter schedule is posted on the course website - check the quarter
schedule frequently for changes, assigned homework problems, iSolve due dates,
exam dates, practice exams, exam keys, classnotes, etc. Additional information
will be posted on the web as the quarter develops - **check the quarter
schedule for the course regularly**.

Exams

There will be four one-hour exams and a comprehensive final exam. See the quarter schedule for dates. If a student is not able to be in class on the day an exam is scheduled and has notified the instructor before the exam date, an alternate time will be scheduled for the student to take the exam (preferably before the date scheduled for the exam).

Students will be provided with a copy of the "TABLES AND FORMULAS FOR MOORE" formula/table salmon colored insert found in the course text on every exam. If you purchased a used text and do not have the insert, you can download a 6 page pdf version of the insert here. As the quarter progresses make it a practice to become familiar with the material included on the insert. Students will be expected to use their scientific calculators competently on exams to perform necessary statistical computations.

Grades

iSolve assignments, one-hour exams, the final exam, and additional assigned activities will be the assessment tools used in the course. The final iSolve homework point total will be scaled to 200 points, the four one-hour exams are weighted to 100 points each, the final exam is weighted to 150 points, and points for other assigned activities will be determined when the assignment is made.

Final grades are simply a function of the percentage of possible points earned:

Let *p* be the percent of the possible course points earned
by a student, the course grade is then given in the following table:

93% <= p<=100% |
-> | A |

90% <= p <93% |
-> | A- |

87% <= p <90% |
-> | B+ |

83% <= p < 87% |
-> | B |

80% <= p < 83% |
-> | B- |

77% <= p < 80% |
-> | C+ |

73% <= p < 77% |
-> | C |

70% <= p < 73% |
-> | C- |

67% <= p < 70% |
-> | D+ |

60% <= p < 67% |
-> | D |

0% <= p < 60% |
-> | F |
