Required Text Understandable Statistics Ninth Edition  by Brase/Brase

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 154 or an equivalent class within the past two years, or a satisfactory score on the assessment test.

Grading Policy Your letter grade will be based on your percentage of possible points.

A 90 -- 100%         C 70 -- 79%

B 80 -- 89%            D 60 -- 69%

Homework: .................................................100 points

Exam 1: October 15 ....................................150 points

Exam II: November 5   .................................150 point

Exam III: December 5   ........................... 150 points 

Project 1:  October 5   .............................. 75 points

Project 2:  November 17 ............................... 75 points

Project 3:  November 26 ................................75 Points

 

Final Exam: December 8   ...........................   225 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 elect to take the exam up to two days before the exam is scheduled.  Without a proven medical excuse, a 10% per day penalty will be given for each day the exam is taken late.  If all homework assignments are turned in for the quarter, and no more than three assignments are late, then the midterm with the lowest score will be dropped.

 

Homework Policy  Homework is due either at the end of class or by 5:00 PM in my office.  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.   Homework that is turned in within one week of the due date will be counted as half credit. Homework may be turned later than one week after the due date, but points will not be awarded.

 

Daily Quizzes  The first five minutes of each class, there will be a quiz that covers the main point from the previous  lecture.  Each quiz will count as 20% of the homework grade.  Quizzes cannot be made up and will not be counted unless the corresponding homework is turned in on time.

 

Extra Credit Any student who has turned in every homework assignment may elect to work on an extra credit assignment or project that will count as a few additional points towards either a midterm or the final.  Extra credit assignments will be discussed on an individual basis during office hours.

 

Project Project Three 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.  Click here for a video explanation of StatCrunch for Project 1.  For Project 2, students will conduct a survey and construct a confidence interval and perform a hypothesis test.  Click here for a video explanation of StatCrunch for Project 2.  For Project 3, students will perform regression analysis on the data that they collect.  Click here for a video explanation of StatCrunch for Project 3.  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 may work on the projects in groups, but expectations will be higher for group projects.   You may either submit the project on paper or using ETUDES.  Rubric for the Project Grades

 



OFFICE HOURS:

Monday  ............................  9:30 to 10:30             A210

Tuesday..........................      10:00 to 11:00               MSC

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. 

LEARNING DISABILITIES: If you have a learning disability, be sure to discuss your special needs with Larry.  Learning disabilities will be accommodated.

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 see me.

HOW TO SUCCEED IN A MATH CLASS

  •  Come to every class meeting.
  •  Arrive early, get yourself settled, spend a few minutes looking at your notes from the previous class meeting, and have your materials ready when class starts.
  •  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.
