Elementary Statistics

I.     Course Prefix/Number: MAT 131

       Course Name: Elementary Statistics

       Credits: 4 (4 lecture; 0 lab)

II.    Prerequisite

MAT 110 or the equivalent with a grade of C or better, or an appropriate score on the OCC Mathematics Assessment Test.

III.   Course (Catalog) Description

This course is an introduction to modern statistics for students in physical, biological and social sciences. Frequency distributions, measures of central tendency and variation, elements of probability theory, statistical inference, sampling techniques, and correlation and regression are studied.

IV.   Learning Objectives

1. Analyze techniques for data collection and organization
2. Calculate and interpret measures of central tendency and dispersion for individual and frequency data.
3. Produce and interpret graphs of frequency distributions.
4. Calculate and interpret probabilities
5. Create and interpret probability distributions.
6. Calculate probabilities, mean and standard deviation for the binomial distribution.
7. Determine probabilities and cutoff values for the normal distribution.
8. Apply the Central Limit Theorem to solve problems involving sampling distributions.
9. Produce and interpret confidence intervals for one population parameter including the mean, the standard deviation or variance, and proportions.
10. Create hypotheses, run hypothesis tests, and draw conclusions for one population parameter including the mean, the standard deviation or variance, and proportions.
11. Create hypotheses, run hypothesis tests, and draw conclusions for two population parameters including the mean, the standard deviation or variance, and proportions.
12. Calculate and interpret the linear correlation coefficients and regression lines.
13. Draw statistical inferences using the Goodness- of- Fit Test and Chi-Square Test for Independence.

V.    Academic Integrity

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• 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.
Details of the Code of Academic Conduct can be found in the Student Handbook.
