REQUIRED TEXT:               Understandable Statistics Eighth Edition  by Brase/Brase

 

COUSE DESCRIPTION:      This course will cover data analysis including probability, distributions, sampling, hypothesis testing, confidence intervals, regression analysis, and nonparametric analysis.

 

PREREQUISITE:                  A grade of C or better in Math 154 or an equivalent class within the past two years, or a satisfactory score on the assessment test.

 

CALCULATORS:                 A calculator with built-in one and two variable statistics functions is required for this class.  The TI-30X IIS is one such calculator that is inexpensive.

STUDENT LEARNING OUTCOMES:      

The successful student will:

1.      Design and implement an unbiased study that will produce sound statistical results.

2.      Generate and interpret statistics graphs from data that arise from surveys and experiments.

3.      Implement the rules of probability.

4.      Apply confidence intervals and test hypotheses to make conclusions about data that come from practical applications.

5.      Perform regression analysis to make informed predictions about relationships between quantitative variables.

GRADING POLICY:           Method of Student Evaluation

                                                Homework                                                                   200 points

                                                Daily Quizzes                                                                200 points

                                                Exams (Three at 100 points each)                                 300 points

                                                Projects                                                                        100 points

                                                Final (Covers entire course content)                              200 points                               

 

 

Your letter grade will be based on your percentage of the 1000 possible points.

                                                            A         90-100%        

                                                            B          80-89%          

                                                            C         70-79%                                  

                                                            D         60-69%

                                                                     less than 60%

                                         

EXAM POLICY:                    Grading will be based on progress towards the final answer, and the demonstration of understanding of the concept that is being tested. The more you show me with steps and detail, the better your chances for partial credit.  You provide me the communication and detail in your answers; and I will give you the best grade I can based on that communication and answer.

 

MAKE-UP POLICY:             Daily Quizzes – during the first five minutes of each class, there will be a quiz that covers the main point from the previous lecture. Quizzes cannot be made up; however, two worst quizzes will be dropped. 

For Exams and Final, make-ups are not possible. In the case of a serious emergency, a chapter exam not taken will not be counted toward the final grade. However, it is essential to take the final exam at the scheduled time.

For Homework, you must show your work to get credit, half credit for completion and half credit for selected problems. Homework will be accepted late up to one week after it is assigned for half credit. You can turn in your homework early if you know you are going to miss the class. You can consult a classmate, a tutor, your instructor, or anyone for assistance on the homework.

·        Please come see me if you do not understand my policies.

LEARNING                           If you have a learning disability, be sure to discuss your special needs with me

DISABILITIES:                    during the first week of class. Learning disabilities will be accommodated.
