Link to Class Rubric**Class Assessment:**

This course will consist of one final cumulative examination, weekly quizzes, weekly participation in grouped discussion threads, and weekly homework assignments.

**Grading:**

Grading:

8 homework assignments, 30 points each, total of 210 points.

7 quizzes, 15 questions each, 30 points each, total of 240 points.

8 weekly discussion postings, 10 points each, total of 80 points.

1 final, proctored examination, 200 points.

Your total grade will be your points earned over the total points possible (730).

The grading scale is as follows:

A = 90-100

B = 80-89

C = 70-79

D = 60-69

F = 0-59

Each student is responsible for:

-Completing weekly reading assignments.

-Participating in weekly discussions.

-Studying various online resources.

-Completing weekly substantial homework assignments.

-Completing weekly online quizzes.

-Completing a proctored examination during Week 8.

You will be evaluated on the total number of points you earn as compared to the greatest amount of points that may be earned in each course activity.

Proctored final examination - A final proctored examination will be taken in a proctored testing environment during the 8th week at one of the Park University sites around the country or at an alternative location. For proctored examinations, photo identification is required at the time of the test. Guidelines for selecting an acceptable proctor can be found on the Park University Website. Other Information on proctored exams: It will be the responsibility of the student to arrange for a proctor, by the 6th week of the term, who is accepted and approved by the course instructor. Approval of proctors is the discretion of the Online instructor. A proctor request form will be made available to you during the first week of class so that you can send your requested proctor to your instructor for approval. Please see the "Proctor Information" section under "Course Home". Failure to take a final proctored exam will result in an automatic "F" grade.

On a weekly basis, each student will need to complete the following items:

1. Discussion Posting

Each student will answer and respond to the posed question, as well as to the postings of the other students in the class. Each student’s overall participation will be graded at the end of the week (out of 10 points), according to the scale below:

Score |
Criteria |

10 |
Student fully participated, answered the posed question completely, and relevantly responded to fellow students thoughts and ideas with insightful and appropriate comments. |

8 |
Student participated, answered the posed question completely, and responded to a mediocre degree to fellow students. |

6 |
Student participated, answered the posed question completely, and responded to fellow students minimally. |

4 |
Student participated by answering the posed question completely, but did not respond in any way to fellow students. |

2 |
Student minimally participated, and would not be considered a part of the “active” discussion. |

0 |
Student did not participate in any way. |

2. Homework

Each student will complete an assigned homework problem set each week (except Week 8). Each problem set will be worth 30 points, and consist of approximately 5-15 problems. Homework assignments are due in the appropriate week’s dropbox by Sunday, 11:59PM Mountain time, or, if the Homework assignment is electronic, then it also must be submitted by 11:59 Mountain Time Sunday. Homework is an individual activity.

Many students have found, however, it helpful to have graded homework returned prior to taking the quiz, also due by the end of the week, Sunday, 11:59PM MT. If you turn in your homework in to the dropbox by Thursday, 11:59PM MT, I commit that I will return it to you by Saturday morning, 11:00AM Mountain Time. This will allow you time to complete the quiz with the returned homework. Homework turned in after Thursday has no guaranteed return time prior to the end of the week.

Homework solutions will be posted in each week’s unit the Monday after the week has ended. For instance, if Week 1 ends on Sunday, 11:59PM MT, homework solutions will post the following day, Monday, at 12:00AM Mountain time. Once the homework solutions are posted, no homework submissions will be accepted.

Each week, there will be an extra credit problem available. It must be completed and turned in the week assigned, and will not be accepted late. There will be no other extra credit available at the end of the term, this is the only extra credit available in the course. The points earned on extra credit will be added to your homework grade each week. Extra credit will only be accepted if it is accompanied by a completed homework assignment.

Finally, it is expected that you complete many additional problems to those assigned. The assigned problems are a sampling of the important concepts in the text. It is expected that to truly master the concepts, you complete many of the odd-numbered problems in the text, as the answers to those problems are given in the appendices of the text.

3. Quiz

Each student will complete a quiz each week, consisting of 15 problems from the assigned reading for the week. The quiz will have a time limit of two hours. It is not expected that the quiz will take two entire hours, rather, the time limit is to ensure that the quiz be completed in its entirety at one time. A student’s grade will be immediately posted in their gradebook, but no correct/incorrect markings will appear on the quiz. The quiz solutions, in their entirety, will be posted in the week’s unit along with the homework solutions, on Monday 12:00AM Mountain Time. Similar to the homework, once the solutions are posted, quizzes must be complete.

4. Other Information

Each week there will be a discussion thread entitled “Study Group”. Posting in this discussion is optional, but I encourage each student to review the postings in this thread. This is where students should post questions about concepts presented in the week’s material. It can be a great resource to learn from your fellow students. This is the place to ask questions about the odd-numbered problems or any of the example problems you may be struggling with. Please feel free to post a response to another student. I will confirm or correct any information posted in this thread.

I send out quite a bit of information via email. Please commit to checking your PirateMail account daily; or please make use of the fantastic forwarding feature that allows you to send all your PirateMail messages to another email account.

**Late Submission of Course Materials:**

No late work of any kind will be accepted. Weekly quizzes will only be accessible during the week assigned. Solutions to homework and quizzes for each week will be posted at the beginning of the following week. It is the responsibility of the student to have work completed early, not late. Notify the instructor WELL IN ADVANCE of any special circumstances.

**Classroom Rules of Conduct:**

** Policy #1: Submission of Work**A class week is defined as the period of time between Monday 12:01 am MST and Sunday at 11:59 PM MST. The first week begins the first day of the term/semester. Assignments scheduled for completion during a class week should be completed and successfully submitted by the posted due date. Create a back up file of every piece of work you submit for grading. This will ensure that a computer glitch or a glitch in cyberspace won't erase your efforts. When files are sent attached to an email, the files should be in either Microsoft Word, RTF, ASCII, txt, or PDF file formats.

__Policy #2: Ground Rules for Online Communication & Participation General email__

Students should use email for private messages to the instructor and other students. When sending email other than assignments, you must identify yourself fully by name and class in all email sent to your instructor and/or other members of our class. Online threaded discussions are public messages and all writings in this area will be viewable by the entire class or assigned group members. __Online Instructor Response Policy__: Online Instructors will check email frequently and will respond to course-related questions within 24-48 hours. __Observation of "Netiquette"__: All your Online communications need to be composed with fairness, honesty and tact. Spelling and grammar are very important in an Online course. What you put into an Online course reflects on your level of professionalism. Here are a couple of Online references that discuss writing Online http://goto.intwg.com/ and netiquette http://www.albion.com/netiquette/corerules.html.

Please check the Announcements area before you ask general course "housekeeping" questions (i.e. how do I submit assignment 3?). If you don't see your question there, then please contact your instructor. ** Policy #3: Technical Problems **If you experience computer difficulties (need help downloading a browser or plug-in, you need help logging into the course, or if you experience any errors or problems while in your Online course), click on the Help button in your Online Classroom, then click on the helpdesk menu item, and then fill out the form or call the helpdesk for assistance. If the issue is preventing you from submitting or completing any coursework, contact your instructor immediately.

Finally…In this class, we will live by the Golden Rule. I will treat you in the same manner I would like to be treated. Professionalism, maturity, and academic perseverance will be rewarded handsomely. Finally, the only “dumb” question is the one that goes unanswered. You are here to learnâ€”if a subject remains uncertain in your mind, ask for help.

**Course Topic/Dates/Assignments:**

During Week 1, we begin to learn the language of statistics and examine some basic sampling and experimental design strategies. We will also learn strategies for organizing data, and representing data sets in graphs and charts. Discussion of analysis of graphical representations of data will allow us to classify what type of distribution represents a particular data set. We will also learn how mistakes in constructing graphs improperly causes data to be misrepresented. Our online discussions will help you become familiar with the online environment, learn what we hope to achieve from this course, understand my general guidelines and expectations, and assess your interest in the the study of statistics.

During Week 2, we will examine basic calculations used in descriptive statistics including: measures of center, sample mean, and sample standard deviation. We will also discuss descriptive measures for populations, including the use of samples. We will continue discussing basic tools for descriptive statistics, including the use of linear regression and linear correlation.

During Week 3, we will learn what probabilities are and learn some of the basic rules of probability. We will also learn about discrete random probabilities and probability distributions.

During Week 4, we will learn about the normal distribution, areas under the standard normal curve, and working with normally distributed variables. We will also examine sampling error, the need for sampling distributions and and learn how to apply the sampling distribution of the sampling mean.

During Week 5, we begin an examination of inferential statistics. We begin with a discussion of confidence intervals for one population mean. We will also start to examine the basics of hypothesis testing.

During Week 6, we continue to examine hypothesis testing for one population mean. We will then turn our attention to the inferential statistics of two population means.

During Week 7, we will examine the inferential statistics of population proportions and analysis of variance using one-way ANOVA.

During Week 8, we will conclude our examination of topics in statistics by learning how to use the Chi-square distribution to determine goodness of fit and to determine if there is an association between two variables. We will also complete the proctored examination during this week.

**Academic Honesty:**

Academic integrity is the foundation of the academic community. Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. Park University 2006-2007 Undergraduate Catalog Page 87-89

A grade of zero may be assigned for an assignment/quiz/etc. in which Academic Dishonesty is suspected.

In the event of alleged academic dishonesty, an Academic Dishonesty Incident Report will be submitted to an Online Academic Director who will then investigate the charge. Students who engage in academic dishonesty are subject to a range of disciplinary actions, from a failing grade on the assignment or activity in question to expulsion from Park University.

**Plagiarism:**

Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing. Park University 2006-2007 Undergraduate Catalog Page 87

**Attendance Policy:**

Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

- The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
- Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
- In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "W".
- A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
- Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
- Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.

**ONLINE NOTE:**An attendance report of "P" (present) will be recorded for students who have logged in to the Online classroom at least once during each week of the term. Recording of attendance is not equivalent to participation. Participation grades will be assigned by each instructor according to the criteria in the Grading Policy section of the syllabus.
