Class Goals

  1. Students will be able to critically evaluate statistics in the media of their major field of study.
  2. Students will be able to plan, implement and communicate the results of a real-world data analysis to investigate an appropriate hypothesis they have generated.

Group Work: In the real world, you will likely be working as part of a team.  I prefer to let you form teams of your choice, but if teams are not working out (by my observation or student complaint), appropriate changes will be made.

IVCC withdrawal policy: Last day to withdraw is  4/11/13

Effective Summer 2011, students will have the ability to initiate a withdrawal from classes. By completing the form in the Records Office or at, the student is authorizing IVCC to remove him/her from the course. Entering the student ID number serves as the student’s electronic signature. IVCC has the right to rescind a withdrawal in cases of academic dishonesty or at the instructor’s discretion.

Students should be aware of the impact of a withdrawal on full-time status for insurance purposes and for financial aid. It is highly recommended that students meet with their instructor or with a counselor before withdrawing from a class to discuss if a withdrawal is the best course of action for that particular student.

Missed test policy: 

You may make up a test if:
1) you know you will be absent on the days of a scheduled test and  you arrange a time prior to the test to take it early, or
2) you may use your score on the final to replace the first missed exam if you do not wish to make it up. A second missed exam without a physician's  written excuse will result in zero for that exam.  Missed quizzes or group exercises:  cannot be made up for any reason.

Calculator: You will need at least a scientific calculator. You may use a graphing calculator if you want, but you must show all or your work. You may not store any information in the graphing calculator. A random check may occur during exams to check calculator memory. Please remove calculator covers before each exam.

School Closings and Class Cancellations:  In the event of inclement weather, please tune to a local radio station for possible school closings.  Check IVCC's Class Cancellations ( and class announcements at CourseCompass/MyMathLab (

Cheating: If you are caught cheating before the withdrawal date, you will be withdrawn from the course with a W. If you are caught cheating after the withdrawal date, you will receive an F for the final class grade.

You are expected to attend all classes regularly. If absence is unavoidable, it is your responsibility to find out what you missed.

Policy: All IVCC student policies apply to this class.

Special Needs: If you are a student with a cognitive, physical or psychiatric disability you may be eligible for academic support services such as extended test time, texts on tape, note taking services etc..  If you are interested in receiving academic support services, please contact the Special Populations Office at 224-0284, office B-204.

Possible Extra Credit
During class there will be some opportunities for students to receive extra credit for going to the board.  After the class is given a problem to work in class during a typical lecture, I will ask if anyone wants to go to the board and show what they did on the problem.  If you just show the problem, you will get 2 points extra credit.  If you explain what you did, you will get 5 points extra credit.  This will be discussed in more detail the first day of class.
