PLEASE NOTE: It is expected that you will have access to a scientific calculator. You will not be allowed to use a programmable, graphing, or statistical calculator on your final exam, nor will you be able to use a computer, so you will need to take a hand-held scientific calculator with you for the final exam. I suggest you use the same calculator throughout the course. Then you will be familiar with it and will avoid having to learn how to use a new calculator at final exam time.

Link to Class RubricClass Assessment:
Each week there will be two scored quizzes; one is a REPEATABLE and UNTIMED Practice Quiz, and the other is a ONE-TIME only, TIMED Quiz. You will also be required to participate in the Class Discussion with an answer to a question and a response posting to a classmate's answer. In addition there is a required Introduction thread posting with a required response to a classmate's introduction, and a proctored Final Exam. Reading assignments: Students are expected to read the assigned chapters in the textbook and view the presentations found in the Concept Guide. The Class Discussion questions, Quiz questions, and the proctored Final Exam assumes you have done so.
Your Introduction post will be assessed on whether you completed the assignment, submitted it on time, and if you completed it as explained in the thread instructions. Your response posting to a classmate's introduction will be assessed on whether you completed the assignment, submitted it on time, and if your response addresses some aspect of the your classmate's introduction. The Class Discussion and Study Group threads are our virtual classroom areas. This is where we will do most of our course interacting. It is advisable for you to check out this area several times per week. Good online discussion with your instructor and classmates and answers to your questions will not be possible if you wait until the last day of the week to arrive. Your Class Discussion answers will be assessed on whether you completed the assignment, answered an eligible question correctly and completely, submitted your answer before the stated deadline, and if you completed it using the required format as explained in the thread instructions. Your response posting to a classmate's Class Discussion question will be assessed on whether you completed the assignment, submitted it on time, and if your response is focused on the statistical concept of the answer posting you are responding to. Your responses should have at least two complete sentences that are concept focused. I encourage and expect you to respond freely to each other with affirmations, inquiries, suggestions, and additional thoughts. "I agree" or "good answer" is not expressive enough to earn points as one of your required sentences. In addition, if you merely write that the answer was good because it helped you to understand the concept, I will consider it too general for point consideration. Say why you agree, or why it is a good answer. Before you praise and agree with another's answer, you need to verify that it is correct. If the answer is incorrect and you are agreeing, your response points will decrease. Please respond tactfully to incorrect or incomplete answers as well as the correct ones. Points will be earned by the thoughtfulness of your postings. Focus your comment on the concept covered in the question/answer posting. Many times just the rewording of a thought, or giving an example, will enable someone to gain a better understanding of a concept, and is acceptable. A great deal of your learning can take place in this academic atmosphere. You can post as many response postings as you want, BUT please understand you can only earn a maximum of five points per week for replying to discussion questions, NOT five points per reply. Your Practice and Timed quizzes will be assessed on whether you completed the quizzes, and submitted the answers before the deadline stated in the instructions. I will publish an Answer Key for the Practice Quiz after the assignment deadline. You will find it in the Course Menu as the last item of the unit in which it assigned. Upon completion of your Timed quiz you will be allowed to see the correct answers. Use these as re-learning tools of any concepts you may need more help on. They will also come in handy as you review for your final exam. The Final Exam will test you on all the material covered in the first seven weeks of the course. It will be a OPEN BOOK and OPEN NOTES exam, and you will be allowed to use a non-programmable, non-graphing, non-statistical calculator. It must be taken in person (requiring a photo identification) no later than Thursday of the 8th week of instruction at one of the Park University campuses around the country. If one is not available in your area, I will approve a non-Park proctor if the Guidelines for selecting an acceptable proctor, found at the Park University Website, are followed. It will be your responsibility to insure that your approved and accepted proctor form reaches me by the end of the sixth week. Fifteen BONUS points will be earned by all who have an APPROVED AND ACCEPTED proctor form to me before the end of the 3rd week of the term. (Please note: All non-Park proctors must be approved by me before they are sent on to your proctor for acceptance. These two procedures take time, so if you wish to earn these bonus points, you should begin immediately securing a qualified proctor. Then you will have all of the necessary information ready when the online proctor form link is made operational.) Fifteen PENATLY points will be assessed on the Final Exam if your proctor form is not submitted to me before the end of the 6th week of the term. You will receive a confirmation on the approved proctor form at the same time I receive my copy. So, you do not need to send me a copy of the one you receive, and if you have not received a copy, I have not either! Failure to take a proctored final exam will result in an automatic "F" grade for the course. ______________________________________________________________________________________________The Study Group thread is a good place to go when you get "stuck." Look through the postings for information to help you get "unstuck." If you do not find help to get you "over the hump," post your question. Please do not ask for an answer to a particular quiz problem. Rather ask specific questions on how to find information that will lead you to be able to complete the assigned problem. You might want to ask for clarification of the reading assignment, or if someone could give you an example of a concept. This is also an area where you can post technical questions. You may post as many questions as you like here. When replying to Study Group postings, please do not give answers to particular quiz problems. Take on the role of tutor and help your classmate gain an understanding of the material. It is well known that we learn by doing and by teaching, so please take advantage of this opportunity. I feel confident that you will be able to help each other in your reply postings, but please know I will be monitoring this thread and will occasionally expand, clarify, or correct replies to posted questions if I deem it necessary. I will also answer questions posted here that do not elicit an answer from classmates. Two cautions: Please refrain from negative comments in the Study Group thread. Its purpose is to ask for help and to help others, not to vent! Under no circumstances are you to post answers to the quiz questions in the Discussion Question or the Study Group threads. Doing so will earn you a 25 point penalty!
Late Submission of Course Materials:
Assignments are expected to be completed by set deadlines. A 24 hour extension is provided for thread postings, but will be assessed with a 50% penalty on earned points. Practice and Timed quizzes will only be accessible during the current week. NO EXTENSIONS WILL BE MADE. You have all week to complete the quizzes; waiting until Sunday is NOT a good plan. Since the Practice quiz is repeatable, you could complete the questions as you are reading the sections and working practice exercises in the textbook. Many students enter and submit one answer at a time on the Practice Quiz to insure accuracy. If you submit all answers at one time, you will only receive a report stating the number of correct answers, but not specifically which ones are correct! You can send me a request to review your quiz and let you know which ones are incorrect. That is never a problem for me to do, but if you do not want to wait for me to reply, you should consider entering your answers separately. This is ONLY for the Practice Quiz! You must submit all answers at one time on the Timed Quiz since you can only enter it one time.
Classroom Rules of Conduct:
Computer literacy is expected: You are expected to have sufficient access to a personal computer with a modem and web browser, access to the Internet, and to use your PIRATEMAIL e-mail account. Please do not request special allowances if you do not have a way to access the course or your PIRATEMAIL.Policy #1: Submission of Work. A class week is defined as the period of time between Monday 12:00 am MT and Sunday at 11:59 PM MT. (MT is Mountain Time at Denver, Colorado, where eCollege is located. When Denver is in Daylight Saving Time, the course will be also. Please make sure you adjust your classwork schedule to meet the MT deadlines.) The first week begins the first day of the term. 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 as attachments, they should be in either Microsoft Word, Microsoft Works, RTF, ASCII, txt, PDF, JPEG, or TIFF file formats. WORDPERFECT and some scanner files (like .max) are not acceptable for this course. Policy #2: Ground Rules for Online Communication & Participation. Journal: You should use this communication tool for private messages to me. Make sure you choose the option to allow me to view your entry. Should you need to send me an attachment of your work, you will need to send it via an email.
General email: You should use email for private messages to me and your classmates. When sending me an email, you must identify yourself fully by course number, section letters, and last name in the SUBJECT LINE of your email: MA120 DL, your last name. PLEASE DO THIS ON EVERY EMAIL THROUGHOUT THE ENTIRE TERM.
Threaded discussions: are public messages and all writings in this area will be viewable by the entire class.
Instructor Response Policy: I am required to check my email frequently and respond to course-related questions within 24-48 hours. Seldom a day goes by that I am not reading and responding to emails and thread postings.
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. PROOFREAD AND USE THE SPELLCHECK TOOL FOR ALL THREAD POSTINGS. Policy #3: What to do if you experience technical problems or have questions about the online classroom. 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. (I HIGHLY SUGGEST YOU JOT DOWN THE PHONE NUMBERS OF ECOLLEGE AND PARK HELPDESK FROM THE WEBSITES NOW. In case you cannot enter the course or Park websites later you will have the numbers to call.)
This course provides an introduction to the world of statistical analysis. Each week we'll focus on different aspects of the general topic. In Unit 1 we'll learn what the topic of statistics entails. We'll discuss some ways to collect the needed data for a statistical study. By the end the unit we'll have a view of how the two distinct divisions of statistics, descriptive and inferential, are related. In Unit 2 we'll discover how to convert pure data into corrupted data, also referred to as ungrouped data into grouped data. Then we will examine some of the many ways data can be visually displayed. We will finish with a consideration of a method matching and graphing two sets of data to analyze the possibility of a relationship. We will return to this analysis graph again in Unit 8 when we discuss correlation and regression. In Unit 3 we will examine ways to describe data by looking at its central tendency, its variation from its center, and how to determine the location of an element within a data set. A method of finding the proportions of variation a data set possesses will also be covered. In Unit 4 we'll explore the basic concepts of probabilities, the branch of mathematics that allows us to take a sample and make predictions about the population from which it was derived. We'll strive to gain a fundamental understanding of probability through its addition, multiplication and counting rules. In Unit 5 we combine the probability concepts and the statistical concepts we previously learned to construct discrete probability distributions. Then we'll learn how to find statistics of the distribution. The unit ends with a discussion on a specific discrete probability distribution called the binomial distribution. In Unit 6 the discussion changes from discrete distributions to continuous random variable distributions. We begin looking at the Normal Distribution and then quickly moving on the Standard Normal Distribution. We conclude the unit by learning how the Central Limit Theorem can be applied to sample data sets. In Unit 7 we move into Inferential Statistics. We learn how to use a sample mean to estimate the population mean, and how we can confidently report its value within a specific interval. In Unit 8 we will examine the basics of hypothesis testing by using one-sample procedures for the hypothesis test of the population mean. In addition we will conclude our examination of topics in statistics by discussing the purpose of regression and correlation analysis. First, we'll examine some introductory terms, then focus on simple linear regression analysis and simple linear correlation analysis. During this final week of the course you will also complete the proctored Final Exam and the Course Evaluation.

I began teaching and tutoring for Park University at the Mountain Home AFB, Idaho Campus in 1993. Until April 31, 2005, I was also the Testing Center Supervisor for LaserGrade Computerized Testing (Yes, one of those "official" proctors!). I watched the Park University Online Program grow from a handful of instructors and students to its present day size. As an online instructor I have been required to take several online instructional courses, and have also received my PhD in Adult Education, specializing in Online/Distant Learning. I have developed many courses in various fields of study, for example: Advanced Aerodynamics, Algebra, and Accounting, just to name a few. So you might say I have experienced the online program from the viewpoint of a student, a proctor, an instructor, course developer, and in a limited way, an administrator! During the continual growth period there have been numerous changes and improvements. Please read more about me in my introduction posting.
I pledge to do my best as your instructor. Will you do the same as my student? If so, let's work together and hopefully we will all learn something new.
