IV. Learning Objectives
- Compute measures of central tendency and dispersion.
- Construct, interpret, and graph frequency distributions.
- Calculate and interpret probabilities using sample spaces, independence, and counting formulas.
- Create, analyze and interpret probability distributions, including the binomial distribution.
- Use z-scores to compute probabilities from normal distributions.
- Apply the Central Limit Theorem to solve problems involving sampling distributions of the sample mean.
- Use confidence intervals to estimate a population parameter, including means and proportions.
- Use hypothesis testing to determine if a hypothesis about a population parameter should be rejected.
- Draw statistical inferences about a single population’s mean, standard deviation, variance, and proportion.
- For two populations, draw statistical inferences about the difference of their means, standard deviations, variances, and proportions.
- Calculate and apply linear correlation coefficients and regression lines.
- Draw statistical inferences about multinomial experiments and contingency tables.
- Draw statistical inferences about three or more populations using analysis of variance.
- Use technology to solve applications drawn from the topics presented in class.
V. Academic Integrity and Student Conduct
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.
There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Please review the Code of Academic Conduct and the Code of Student Conduct, both located online at

VII. Methods of Instruction
Methods of presentation can include lectures, discussion, demonstration, experimentation, audio-visual aids, group work, and regularly assigned homework. A TI-83 or 84 graphics calculator will be used for instructional purposes. Other technology will be used when appropriate.
Course may be taught as face-to-face, hybrid or online course.
VIII. Course Practices Required
Course practices can include attendance, assignments, special projects, classroom activities and assessments.
Course may be taught as face-to-face, media-based, hybrid or online course.
IX. Instructional Materials
Within the Schedule of Classes, textbooks can be found by clicking on an individual course section and looking for the words "View Book Information".
Textbooks can also be found at our Mathematics Textbooks page.
Other Required Materials: A TI-83 or higher model graphics calculator.
X. Methods of Evaluating Student Progress
(To be completed by instructor)
Evaluation methods can include graded homework, quizzes, chapter or major tests, individual or small group projects, calculator/computer projects and a final examination.
The following applies to the online section of this course only:
This online course requires that students take their exams as directed by their instructor: either on campus at Oakton's Testing Center, at an authorized testing center with a face-to-face monitor, or remotely through a pre-approved testing service. (To be customized by instructor.)
XI. Other Course Information
If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center at the Des Plaines or Skokie campus. All students are expected to fulfill essential course requirements. The College will not waive any essential skill or requirement of a course or degree program.
Oakton Community College is committed to maintaining a campus environment emphasizing the dignity and worth of all members of the community, and complies with all federal and state Title IX requirements.
Resources and support for
- pregnancy-related and parenting accommodations; and
- victims of sexual misconduct
Resources and support for LGBTQ+ students can be found at www.oakton.edu/lgbtq.
Electronic video and/or audio recording is not permitted during class unless the student obtains written permission from the instructor. In cases where recordings are allowed, such content is restricted to personal use only. Any distribution of such recordings is strictly prohibited. Personal use is defined as use by an individual student for the purpose of studying or completing course assignments.
For students who have been approved for audio and/or video recording of lectures and other classroom activities as a reasonable accommodation by Oakton’s Access Disabilities Resource Center (ADRC), applicable federal law requires instructors to permit those recordings. Such recordings are also limited to personal use. Any distribution of such recordings is strictly prohibited.
Violation of this policy will result in disciplinary action through the Code of Student Conduct.
