TEXTBOOK: Introductory Statistics 9th Edition, Neil A. Weiss, Pearson, Addison-Wesley, 2012

PREREQUISITES: One College Level Math Course or Appropriate Score on Placement Test

CALCULATOR: TI-83 or TI-84 calculator families. Some exam questions may be based on the use of this calculator. No cell phones, smart phones, no computers of any kind, no TI-89 or TI-92 or Hewlett Packard or any other “self-integrating and differentiating” calculators are permitted during exams. Please bring your calculator to each class. During exams calculators may NOT be borrowed from other students.

ATTENDANCE: Attendance will be taken each class. Any student who is absent at most two times will have their lowest test grade dropped.

CLASS PARTICIPATION: Please come to each class prepared with your textbook, notebook (preferably a graph notebook), worksheets and calculator. Preparedness is essential to participation. Please be prepared to participate in class at all times. Your grade will reflect your preparedness and participation.

Cell phones, smart-phones, laptops, and notebook computers: to maintain a courteous, undistracted educational environment and as a respectful gesture to myself and all others, all such devices must be turned off during class; no sending or receiving text messages, phone calls or e-mails during class. Exceptions are allowed only for students who have had a conversation in advance of any device usage.

LATENESS: Please arrive to class on time and be ready to learn. Lateness is a distraction to the class as a whole. Three times late equals one time absent.


HOMEWORK ASSIGNMENTS: Homework will be assigned at every class session. Be prepared to hand in your work for a grade at any time. This may or may not be announced in advance. Students are expected to dedicate 2 hours of study/practice outside of class for each hour of seat time.

TESTS: Tests will be scheduled with a reasonable amount of notice. Therefore, there will be no make-ups allowed.

GRADING POLICY: Cumulative Final Exam 20%

Tests 40%

Quizzes/ Technology Assignments 30%

Attendance/Participation 10%

COURSE WITHDRAWAL: Any student may withdraw from this course with a grade of W at any time until Monday, July 20, 2015. After then, a student who does not complete the course will receive a grade of F. The grades of WP, WF, and Incomplete are awarded only in exceptional circumstances beyond the student’s control. This is in full compliance with WCC policy.

Grade Calculation

Since this is a weighted system, it is not as simple as adding the points you earned and dividing by total points. Use the table below as a guide for grade computation or visit: tcann.wikispaces.com

Quiz / Points Earned / Points Total
Sums:

Quiz Average (quotient of sums above) = ______(convert to %)

Tests / Points Earned / Points Total
Sums:

Test Average (quotient of sums above) = ______(convert to %)

Final Exam Score= ______/100

Participation= ______/10

If you are eligible to drop a test grade, then the breakdown would be as follows:

Tests 60%

Quizzes/ Technology Assignments 30%

Attendance/Participation 10%

where the three strongest scores from Test 1, 2, 3 and the Final are plugged into the “Tests” table above.

Then you can compute your final average by multiplying your test average by 0.6, your quiz average by 0.3, and adding those two values together with your participation grade.

If you are NOT eligible to drop a test grade, then the breakdown will be as follows:

Cumulative Final Exam 20%

Tests 40%

Quizzes/ Technology Assignments 30%

Attendance/Participation 10%

In this case you will compute your final average by multiplying your final exam grade by 0.2, your test average by 0.4, your quiz average by 0.3, and adding those two values together with your participation grade.
