Textbook and other materials
Elementary Statistics, A Step by Step Approach (5th Edition) by Allan G. Bluman
TI 83 Graphing Calculator
Prerequisites
Math 150 or Math 120
Course Description
This is an introductory course in descriptive and inferential statistics for students in business liberal arts, psychology, and science. Topics will be selected from numerical and graphical descriptive methods, probability and random variables, sampling methods, binomial distribution, normal distribution, correlation, regression, hypothesis testing, confidence intervals, and sample distributions.
Attendance
Regular attendance is essential for success in this class. However, if it is necessary to miss any class period, the student is responsible for any announcements made, sections covered, and assignments.
Students are expected to be punctual and attend class for the full session. The nature of this course requires that you be present in order to learn the skills necessary for effective growth in mathematics. Class participation may make the difference between grades if a student’s scores place him/her on the borderline.
Student Responsibilities
Students are expected to be adequately prepared for each class session. It is reasonable to expect at least two hours of outside study for every hour spent in the classroom.
Students are expected to assist in maintaining a classroom environment that is conducive to learning. Therefore, free discussion, inquiry, and expression are encouraged. Behavior that interferes with the instructor’s ability to conduct the class or the ability of students to benefit from that instruction is not acceptable.
Exams
There will be four exams including the final exam, with each exam weighted equally toward determining the final grade for the course. Each exam will cover the only the chapter sections studied since the previous test. The final exam will take place on the last day of class.
Missed Exams
Makeup exams are only an option under emergency conditions. A missed exam will result in a zero score. If you miss an exam because of an emergency, you must notify the instructor the day of the exam (via email or message with the faculty receptionist). The student must provide the instructor with a letter of explanation before the next class period with any attached documentation. The instructor will review the letter and inform you by the next class if and when a makeup exam will be allowed.
Assignments
Weekly assignments, minitab assignments, and review quizzes will make up the assignments portion of the course final grade. All assignments will be weighted equally. Each student is responsibility to complete the assigned work and hand it in on time.
Each weekly assignment is due at the beginning of the following Tuesday class. Weekly assignments can be done with Minitab or Excel but the student must know how to compute the answers without use of a computer for the Exams.
Minitab assignments are to be completed by using Minitab software which is available in the Computer Lab. Each Minitab assignment will have its own specific due date with a lead time of about two to three weeks.
There will be a review quiz given during class time prior to each exam.
Missed Assignments
Review quizzes must be taken during class time and cannot be made up. Assignments handed in late will lose 10 points (out of 100 points) and 10 points for each additional week it is late.
Academic Dishonesty
Any use of unauthorized aid or obtaining any help from another individual during a test is considered cheating. Any student caught cheating on a test will receive a score of zero for that test and a formal report will be filed with the Dean of Students.
Academic Math Center
The Mathematics Center (room 2220, phone number 488-4294) is a place where students can receive help in areas where they are struggling. Please take advantage, if necessary, for this free service for KVCC students. Call ahead to find out when the “Stats” tutor will be available.
Course Grade Determination
The student’s final grade will be determined as follows:
Assignments 40%
Four Exams (15% each) 60%
Total 100%
Grading Scale
90% to 100% = 4.0
85% to 89% = 3.5
80% to 84% = 3.0
75% to 79% = 2.5
70% to 74% = 2.0
65% to 69% = 1.5
60% to 64% = 1.0
0% to 59% = 0
