Text (Optional): Elementary Statistics Using the TI 83-84 Plus Calculator 3rd Edition by Mario Triola.

Required Software License :  It is required to have a software license to use the software MyStatLab in this class.  Students have two choices.  The first choice is to purchase the textbook new from the bookstore.  The textbook comes with the software license.  The second choice is to purchase the license alone either from the bookstore or online at coursecompass.com.  The license gives you access to the textbook online.  This is a more economical choice, but is only recommended to students who have online access and feel comfortable reading a computer screen instead of a traditional book.  If you purchase a used textbook, you will also need to purchase the software license.  The software license is valid as long as the student uses the same textbook.  When you first attempt to log on you will need to put in the following course ID:  walker78229. 

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

Student Learning Outcomes

  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.
     

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

Exam Policy Students are to bring calculators, pencils or pens, and paper to each exam. You may bring one 3" x 5" note card with writing on the front and back to each regular exam and two such note cards to the final 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 must let me know in advance.  With a valid excuse for a missed exam, the same score will be assigned to the missed exam as received on the final exam. No more than one of these three exams may be missed and the final exam can not be missed. In class quizzes cannot be made up.

Homework and Quiz Policy  Homework and quizzes will be worked out online.  Homework is due every Saturday night at midnight but you should complete it before the in class quiz on Thursday.  Quizzes are due on Midnight on Sunday and also should be completed before the in class quiz.  Online quizzes may be taken many times (before midnight on Sunday) until you are satisfied with you score.  Homework and quizzes may be worked on after the after the due date, but points will not be awarded. To work on a homework assignment or a quiz after the due date, go to the item labeled "Late" in the list.  This can be especially helpful for review.  You may also go to your Study Plan to review.

Projects Two projects will be created for this class.  For Project 1, students will collect quantitative data and use a computer to display each of the charts discussed in class.  For Project 2, students will conduct a survey and construct a confidence interval and perform a hypothesis test.  Each project will include the computer results and a narrative describing data collection, assumptions made, background information, how the data was analyzed, and conclusions.  Unless specifically stated, all results must be computed using a computer and the computer generated results must be included with the project.  The projects should be typed, double spaced, and have 12 point font. Students are to work in pairs. If you cannot work with a partner, then speak to your instructor about the possibility of working as a trio.  A 5% penalty will be incurred on any student who cannot work with another student.  

Office Hours: To Be Announced

 

 

CALCULATORS: TI 84+ is required for this course.  Other calculators are not feasible for this class as they are missing some of the statistical functions necessary to do the homework, quizzes, and exams. There are a limited number of TI 84+ calculators available for rent for $10 at the Library. 

LEARNING DISABILITIES: If you have a learning disability, be sure to discuss your special needs with me.  Learning disabilities will be accommodated and you may contact our disability resource center by email or by phone at (530) 541-4660 x 384.

TUTORING:  Tutors are available at no cost in A 201 (The Math Success Center).

A WORD ON HONESTY:

Cheating or copying will not be tolerated. People who cheat dilute the honest effort of the rest of us.  If you cheat on a quiz or exam you will receive an F  for the course, not merely for the test.  Other college disciplinary action including expulsion might occur. Please don’t cheat in this class.  If you are having difficulty with the course, please contact me.

  •  Read each section before it is discussed in class.
  •  Do some math every day.
  •  Start preparing for the tests at least a week in advance.
  •  Spend about half of your study time working with your classmates.
  •  Take advantage of tutors and office hours, extra help can make a big difference.
