Principles of Statistics (STA-201) is designed to meet the needs of students in many disciplines and professions. The sciences, social sciences, and business are increasingly using quantitative methods. This course provides the tools and techniques needed to design studies that provide representative data for mathematical analysis and statistical interpretation. Topics include types of statistics, data representations (tables, graphs, and charts), measures of location and variation, probability concepts, continuous and discrete distributions, confidence intervals, hypothesis tests, and regression and correlation analysis. The emphasis of the course is on the application of statistical methods to real-world problems. In solving these problems, you are required to use the appropriate notation and formulas. Problems may be viewed as statistical studies, and as such you should be able to interpret results and justify conclusions.
The overall objective of Principles of Statistics is to provide you with the skills needed to perform statistical computations and analyze data. These skills have practical applications in many disciplines, including the sciences, technology, and the social sciences. Upon completing the course successfully, you should be able to:
You will need the following texts to do the work of the course. Both texts are available from the textbook supplier, MBS Direct.
Principles of Statistics is a 3-credit online course, consisting of nine (9) assignment modules grouped into five study units.
For your formal work in the course, you are required to participate in two (2) online discussions, complete nine (9) written assignments, and take two (2) examinations: a proctored midterm examination and an unproctored, online final examination. For the course's five study units and nine assignment modules, go to the Assignment Modules area of the course Web site. (See also the course Calendar.)
Principles of Statistics requires you to participate in two graded discussion activities, in addition to an ungraded, but required, "Introductions" forum in module 1. The two online discussions are based on chapter case studies and take place either on the class Discussion Board or in separate group discussion forums within the Groups area of the course Web site. The mentor will determine and specify which option will be used for each case study. Group discussions are governed by certain ground rules. Please read these "ground rules" carefully for information on how to proceed when asked to participate in a group discussion activity. Consult the course Calendar for all due dates associated with the discussion activity. Communication with the mentor and among fellow students is a critical component of online learning. Participation in online discussions involves two distinct activities: an initial response to a posted activity and subsequent comments on classmates' responses. Meaningful participation is relevant to the content, adds value, and advances the discussion. Comments such as "I agree" and "ditto" are not considered value-adding participation. Therefore, when you agree or disagree with a classmate, the reading, or your mentor, state and support your agreement or disagreement. You will be evaluated on the quality and quantity of your participation. Responses and comments should be properly proofread and edited, professional, and respectful. For additional information on online discussions, see Online Discussions in the Online Student Handbook.
Each assignment module concludes with a written assignment that you are to complete and send to your mentor for correction and grading. The written assignments draw on even-numbered exercises from assigned sections in the textbook. For each assignment, answer all exercises, and show all work. Assignments must be prepared electronically using whatever word processing program you have on your computer. Be sure to use statistical notation and formulas appropriately. (Note: For better results in preparing your assignments, consider upgrading your word processor's equation editor to the latest version of MathType.) When preparing your answers, please identify each exercise clearly by section and exercise number. Include your name at the top of the paper, as well as the course name and code and the semester and year in which you are enrolled. Before submitting your first assignment, check with your mentor to determine whether your word processing software is compatible with your mentor's software. If so, you can submit your work as you prepared it. If not, save your assignment as a rich-text (.rtf) file, using the Save As command of your software program. Rich text retains basic formatting and can be read by any other word processing program. When satisfied that your assignment represents your best work, submit it to your mentor by means of the
>>View/Complete Assignment link provided at the bottom of the respective assignment page. Use the Browse button within this link to locate and attach your assignment file. Click You are required to take two examinations: a proctored midterm examination and an unproctored, online final examination. Consult the course Calendar for the scheduling of these exams. Midterm Examination The exam is open book, but not open notes. In this regard you are permitted to bring only a scientific (nongraphing) calculator and the authorized textbook to the exam. The textbook must be an original bound hard copy; electronic textbooks (or printouts) are not allowed. You are also not allowed to bring any loose pages or notes, either typed or printed, or to consult a solutions manual or any other reference sources or sources of information. Programmable calculators are not permitted in examinations. You may take the examination only during the designated exam week, at an approved location, and with an approved proctor. In this regard, you need to schedule your exam and submit your "Proctor Request Form" with the necessary documentation no later than the end of the first week of the semester (see Administrative Forms in the General Information area of the course Web site). If you are on a course extension and have not yet taken the midterm exam, you must let your examination proctor know when you plan to take the exam and contact the Office of Test Administration (609-984-1181) two weeks in advance to request that your exam be sent to the proctor. For more information on scheduling a proctored examination, see the section Examinations and Proctors in the Online Student Handbook. Final Examination The exam is open book, but not open notes. In this regard you are permitted to use only a scientific (nongraphing) calculator and the authorized textbook. But you are not allowed to consult a solutions manual, notes of any kind (including graded or ungraded assignments), or any other reference sources or sources of information. The final exam is taken online in Blackboard. An exam link will be activated and made available to you in the Tests & Quizzes area of the course site at the start of the last week of the semester. You may take the exam at any time during that week, but no later than midnight Saturday (eastern time). If you are on a course extension, you will need to arrange with your mentor a time to reschedule the final exam. Statement about Cheating If there is evidence that you have cheated or plagiarized in your exam, the exam will be declared invalid, and you will fail the course. Please also note that the exam is time-limited. That means you only have the allotted time in which to complete the exam. If you exceed the time limit on the exam, you will be penalized by having two points deducted for every minute that you exceed the time limit. This may also result in your failing the course. Your grade in the course will be determined as follows: To receive credit for the course, you must earn a letter grade of D or higher on the weighted average of all assigned course work (e.g., exams, assignments, discussion postings, etc.). You will receive a score of 0 for any work not submitted. Letter grades for online participation, written assignments, and examinations are based on the following numerical grades: First Steps to Success Study TipsCompleting Assignment Modules Study TipsPreparing for the Examinations Study TipsThe Language of Statistics In statistics we use symbols to communicate results, and we combine these symbols into formulas (mathematical sentences) that define how to use the data to obtain the desired results. These are the conventions of statistics, and you will be expected to use the appropriate symbols and formulas when presenting solutions to exercises. As you study each section in the textbook and encounter new symbols and formulas, you may want to write them down in a list, along with their meaning (in the case of a symbol) or description (in the case of a formula). For an illustration, click Sample List of Symbols and Their Meaning.
