Required Text Understandable Statistics Eighth Edition  by Brase/Brase

Course Description This course will cover data analysis including probability, distributions, sampling, estimation, hypothesis testing, confidence intervals, regression analysis, and ANOVA.

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.

As a Courtesy to everyone in class, please turn off your cell phones.  Thank you.

 


 

Students with disabilities must identify themselves to me within the first two weeks of class.

Accommodations for Students with Disabilities: Students requiring accommodations for a certain disability that may affect class performance are requested to schedule with a staff member at the DRC to discuss this during the first week of the quarter so that appropriate arrangements can be made.        Course materials available in alternate format. 

Course Objectives

  • Understand basic fundamental statistical theories and how these theories are applied to real world phenomena.
  • Understand the basics of probability theory and probability distributions which will be applied to the statistical tools presented.
  • Demonstrate a working knowledge of statistical estimation concepts.
  • Understand hypotheses testing and confidence intervals.
  • Become proficient with utilizing a computer for the analysis of data.
  • Follow current events that make use of statistical concepts.

Grading:  Your class letter grade will be based on the usual grading scale:

 

A:  90% and above,     B: 80-89%,      C: 70-79%,        D: 60-69%,    F: 59% and under

 

                        Homework & Quizzes (50% of 300) 150 points

Midterm Exam 1                                            150 points

Midterm Exam 2                                            150 points

Midterm Exam 3                                            150 points

Projects (3 @ 50 points)                                150 points

                        Comprehensive Final Exam:              250 points      

                        Total                                                               1000 points

Exam Policy: Students are to bring calculators, pencils or pens, and paper to each exam. Grading will based on the progress towards the final answer, and the demonstration of understanding of the concept that is being tested, therefore, work must be shown in detail. Any student who cannot make it to an exam may take the exam up to two days before the exam is scheduled without penalty. Arrangements must be made with me in advance.  There is a 10% penalty for all make up exams. 

Homework Policy: The use of computers or calculators is strongly recommended. Also, feel free to consult a fellow classmate, a tutor, your instructor, or anyone else for assistance on the homework.  EACH SECTION is worth 7 points.  Homework is due every Thursday.  Late Homework that is turned in within one week of the due date will be counted as half credit. Homework turned in more than one week after the due date receives no credit.

Weekly Quizzes:  The first five minutes of Thursday's class will be a quiz that covers the main point from the homework that is due.  Quizzes CANNOT be made up.  Quizzes are worth 10% of the Homework Grade.
Projects:  Each project will include the computer results and a narrative that describes data collection or source, assumptions made, background information, explanation of the data, interpretations and conclusions.  The projects should be typed, double space, and have 12-point font. Include your data in your project. 

Project 1 is due Tuesday, January 31.  You may conduct a survey or experiment to gather quantitative data.   Have at least 30 data points in order to find the mean, median, mode, the trimmed mean, variance and standard deviation of your sample.  Use a histogram AND two types of appropriate graphs to organize your data from the following choices:  stem-leaf diagram, circle graphs, time plots, frequency polygons or ogives. 

Project 2 is due Tuesday, February 21.  You may use resources on-line or in the library to gather data to estimate the mean of (2) large samples.  Use a confidence interval of 95%.  Find the estimate of the difference of means of your samples. 

Project 3 is due Tuesday, March 14.  You may conduct a survey or experiment or use resources on-line or in the library to find paired data, to make a scatter plot and linear regression.  Find your correlation coefficient and write a one-page summary of your data including the relationship of the paired data, the interpretation of slope, and confidence bounds of prediction.  

 

In this class, it is your responsibility to drop the class in order to avoid an unwanted grade. 

You must go to Admissions & Records.

Friday, January 13, 2006 is the last day for refunds.

Friday, January 27, 2006 is the last day to Declare Credit/No Credit.

Friday, January 27, 2006 is the last day to drop with no record.

Friday, March 3, 2006 is the last day to withdraw with a “W” grade.

 

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.  Top of Form

The Gateway Math Center has free math tutoring for all registered students.  The computers at the GMC are available to do homework assignments.  Please Log-in and Log-out so that the facility gets the funds it needs.
