MATH 270 - Introductory Statistics

Class Syllabus - Fall 2008

 Up ] [ MATH 270 - Syllabus ] MATH 270 Class Pace and Assignments ]

Course Description:   This course is a rigorous but non-calculus based introduction to basic concepts from statistics and probability intended for mathematics, computer science and science majors. Topics may include graphical displays of data, measures of central tendency and variability, elementary probability concepts, basic combinatorics, discrete probability distributions including the binomial distribution, the normal distribution, correlation and regression, and confidence intervals and hypothesis testing for means and proportions. Applications will be oriented towards the sciences. Special emphasis is placed upon the understanding of concepts and the proper use of statistics in real life situations.  In order to increase the likelihood of success in this course it is recommended that the student attend class without fail, religiously work the homework, read the textbook, focus on understanding the concepts (not just the rote computations), and seek help from the professor and other sources (tutoring, library, textbook CD and/or website, etc.) when needed. 

Learning Objectives This course will give students a working knowledge of the ideas and tools of practical statistics.  Students will learn to:

  • understand the difference between observational studies and controlled experiments and the scope of conclusions that each permits;
  • conduct and interpret descriptive analyses of data, including graphical and numerical summaries;
  • understand fundamental concepts of statistical inference, such as confidence and significance, including limitations of these procedures;
  • conduct and interpret tests of significance, including Fisher's exact test, binomial tests, z-tests for a proportion and difference in proportions and t-tests for a mean and difference in means;
  • construct and interpret confidence intervals.

Prerequisites:  There are no prerequisites for the course but it is expected that students are familiar with basic mathematical ideas such as functions.

Professor:  Dr. M. Leigh Lunsford.  For Dr. Lunsford's office location, phone number, email address, schedule (including office hours), and other general information, go to her homepage:  http://www.mathspace.com/Lunsford/

Meeting Times and Locations:   TR 11:00 am -12:15 pm, Ruffner 354

Course Textbook:   INVESTIGATING STATISTICAL CONCEPTS, APPLICATIONS, AND METHODS, first edition by Beth L Chance and Allan J Rossman.  The text should include a CD with data sets and Java applets and be bundled with the student version of Minitab 14.

Required Technology/Computer Configurations: 

  • I recommend that you copy the data sets and applets on the CD that comes with your textbook onto your hard drive.  Make sure your computer is configured to run the applets.

  • You will also need to install the student version of Minitab on your laptop.

  • A TI-84 or TI-84 plus graphing calculator is highly recommended for this course.  If you do not use one of these then you will be responsible for knowing how to use your particular calculator. 

  • You will need to have access to Microsoft Office.

  • You will need to have Microsoft Word or another word processing program installed on your computer in order to complete your homework assignments.

Determination of Course Grade:

45% - Two In-Class Exams (22.5% Each)

10% - Group Hand-In Homework

10% - Quizzes

  5% - On-line Practice Homework

  5% - Mathematics Cultural Points
25% - Comprehensive Final Exam

Grades will be assigned on a ten point scale (90's A; 80's B; 70's C; 60's D; 50's and below F).

Honor System:  I expect you to conform to the Longwood University Honor System as contained in the Student Handbook.  All material handed in to me, including on-line work, falls under the honor code.

Homework:  Generally homework in this class will come in two flavors:  homework that is to be handed in and homework that will not be handed in.  It is very important that you keep up with both types of homework.

Hand-In Homework:   You will generally have two types of hand-in homework.  You will have individual homework that will oftentimes be completed on-line via Blackboard.  You will also have group homework assignments.  I will not accept late homework, period.

Non Hand-In Homework:   You will also be assigned non hand-in homework that you are expected to complete.  Your performance on tests and quizzes will most likely be directly proportional to how much of your non hand-in homework you complete.

Quizzes:   About every two weeks we will have a quiz.  The quizzes will be based on your homework and our in-class discussions.  The quizzes will be given out of class thus I will give a time frame during which you can take the quiz.  I will try to give at least one class period notice for an upcoming quiz (please see the Class Pace and Assignments page for the latest information on quiz dates).  Once a quiz has been graded and returned to the students, there will be no make-ups for that quiz, period.  I will drop your lowest quiz grade when computing your quiz average.

Make-up On-Line Work and In-Class Quizzes:  Because I will be dropping your lowest grade for computation of your Quiz average and you have plenty of time to complete your Hand-In Homework, there will not be any make-up quizzes or homework.  If you have a legitimate University sponsored event in which you must participate (such as a sporting event) scheduled on the same days as a quiz, then please see me about taking the quiz early.  Also, if a hand-in assignment is due on a day when you will not be able to come to class, then please make sure you hand in your assignment to me before the class meeting.  

In-Class Exams:  A minimum of a one week notice will be given for exam dates.  Please see the class schedule below for the tentative exam dates (for more detailed information about test dates see the Class Pace and Assignments page).  Except in the case of an emergency, a make-up exam must be scheduled before the scheduled exam date.  If the exam has already been given and you have not previously scheduled a make-up, then you will receive a zero on that exam. 

Final Exam:  The final exam for this course will be comprehensive.  You cannot miss the final.  Failure to take the final exam will automatically result in an F grade for the course.   Please see me as soon as possible if you have a conflict with the final exam date.

Final Exam Dates:    The final exam date is Friday, December 12,  3:00-5:30 a.m. You can find the scheduled final exam dates for all your classes at this link.  If you have a conflict with the final exam date and need to reschedule, please see me as soon as possible.

Mathematics Cultural Points (cults):  In order to receive the full 5% credit for mathematics cultural points you must earn at least 8 cults.  To determine how to earn cults please click here.  All cult submissions must be received by Friday, December 5.  In addition, any cults that you submit as a write-up to a planned event (e.g., a colloquium), must be received no later than 2 class days after the event occurs.  Please note the deadline for obtaining approval for an article to present is Friday, November 21.

Extra Credit:  Extra Credit will NOT be given, period.

Attendance & Excused Absences:   You are expected to attend every class.  If you miss classes it will most likely be reflected in your grades (i.e. you will perform poorly).  The following college attendance policy will be followed per the Class Attendance section of the Academic Regulations chapter of the Longwood University Undergraduate Catalog:  Missing 10% of class meetings may result in a lowering of one letter grade.   Missing 25% of class meetings for any reason will result in an automatic “F” for the course.  Absences are excused only for illness, college sponsored activities, and recognizable emergencies.  You must have the proper documentation for an excused absence.  Student Health Services can provide documentation only for students hospitalized locally or absent at the direction of Student Health Services personnel You must also assume full responsibility for all material covered during your absence, including scheduling any early in-class quizzes or make-up exams.  A grade of "0" will be assigned for all work missed due to unexcused absences.

Resources for Students Learning Statistics:  

  • Me!  I want you to consider me to be your number one resource!  In addition to seeing me during my office hours, you are welcome to call me or send me email if you have questions about your homework.  If you are unable to see me during my office hours please make an appointment with me! 
  • The website for the textbook:  http://www.rossmanchance.com/iscam/
  • I will also try to make answers to homework exercises, etc. available to you via either a reserve folder in the library or on Blackboard.

Office of Disability Services:  Any student who feels s/he may need an accommodation based on the impact of a physical, psychological, medical, or learning disability should contact me privately. If you have not already done so, please contact Longwood's Office of Disability Support Services to register for services.

Class Schedule:  Below is a very tentative class schedule.  This schedule may change due to class pace, etc.  However, it is provided here for your information.  For a more detailed schedule depending on our actual classroom interaction please see the Class Pace and Assignments page.
