2 Columbia College Online Campus P a g e 2 Course Overview In this course we will study the process of statistics: collecting, organizing, summarizing, and analyzing data in order to draw conclusions and answer questions. We will also provide a measure of how confident we are in any conclusions we make. In short, our goal is to learn how to use data to make informed decisions about the world around us. Technology Requirements Participation in this course will require the basic technology for all online classes at Columbia College: A computer with reliable Internet access, a web browser, Acrobat Reader, Microsoft Office or another word processor such as Open Office You can find more details about standard technical requirements for our courses on our site. Additional requirements specific to this course: Adobe Flash Player, The most updated version of Java. You will also need access to MyLabsPlus to complete weekly homework. Course Objectives To choose appropriate statistical methods to solve real-world problems and understand the limitations of the methods in making predictions and drawing conclusions. To use appropriate technology to solve statistical problems. To organize data, communicate the essential features of the data, and interpret data in meaningful ways. To understand the role of probability in the foundation of modern statistics methods. Measurable Learning Outcomes Classify data as qualitative or quantitative (discrete or continuous). Identify advantages and disadvantages of sampling and of common sampling methods. Distinguish between observational studies and experiments and define different types of experimental design. Construct frequency distributions for qualitative data and frequency distributions, histograms, stem and leaf plots, and boxplots for quantitative data. Describe distributions of quantitative data in terms of shape, center, and spread. Compute probabilities using the addition rule, the multiplication rule, complements and simple counting techniques. Determine if events are independent using conditional probabilities. Construct discrete probability distributions. Compute and interpret the mean (expected value) and standard deviation of a discrete random variable. Compute probabilities of binomial experiments. Compute probabilities and find percentile values of normally distributed data. Determine if a data set is approximately normally distributed.

Work through the examples as you come to them on paper with your calculator. You can also find Calculator Video Tutorials in the Content area on D2L. The online text, found on the MyLabsPlus website, has links to video lectures on the material which you may find helpful. : Discussion is completed on the D2L site. You will be expected to actively participate in the discussion each week throughout the course. The discussion board is our classroom. Your reading actively with the calculator notes is part of our course, but the learning happens through our discussion of each concept we learn. Discussion is considered a dialogue between student-student and instructor-student. We learn from discussing in detail the ideas behind the calculations. It is just as important to post questions about areas that are unclear to you as it is to post correct solutions to problems. Effective posts and responses will lead the reader through your thought processes and explain key ideas or where difficulties might arise. The goal is to move beyond: I don t understand how to do number 32 to creating thoughtful and thought-provoking posts. There are a maximum of 5 points for discussion each week. You must post one problem from the Discussion Questions found in Content each week as well as a thoughtful response to at least one problem that another student posts. This response should add to the discussion forum on the topic of the original posting. You may post more if you wish, but no more than 5 points may be earned each week. Each weekly Discussion total is worth 5 points and your top six weekly Discussion scores are counted for a total of 30 points in the class. There is a document in the Course Content which gives more detail about the discussion area of the course. Please read it prior to posting. : Homework is done at MyLabsPlus. Click on the Homework button to find the weekly homework. You will have homework in MyLabsPlus during weeks 1 8. Each week there will be two homework sets that you should complete by midnight on Saturday. The first set has the exercises in the order that the material appears in the textbook. The second set is a mixed practice set. There are 60 points allocated for homework. At the end of the course, whatever percentage you have earned on the homework assignments will be applied to these 60 points. You will see one column in the D2L gradebook for homework. You may track you homework average throughout the course under Grades within MyLabsPlus. MyLabsPlus provides tools to assist you with the homework such as Show me an Example or Help Me

5 Columbia College Online Campus P a g e 5 Solve It. If you use these tools, you will have to complete a similar problem without using the tools in order to receive credit for the problem. Each problem should have a link to the online textbook and most have links to video lectures over the topic as well. You may rework each homework exercise until you get it correct by selecting similar exercise at the bottom of the screen. Once you have completed the MLP homework, there are suggested HW problems from the text you should work on. These do not have to be turned in for grading but are an important part of the learning process. Homework Points: Homework Grades are calculated by multiplying your final percentage in MyLabsPlus by the 60 points allocated for Homework. This is updated at the end of week 8 in the D2L gradebook. You may view your Homework score in the MLP gradebook anytime during the entire 8 weeks. Quizzes: Eight quizzes are given, one per week. Each week, a quiz is posted by noon Thursday in the content area of our class and is due by midnight on Saturday. Submit your quiz by clicking the Quizzes link in our course on D2L, then clicking on the Quiz you are taking. Quizzes are multiple choice and computer graded. Students have unlimited attempts on each quiz during the quiz period. There is a 60 minute time limit on each quiz. Each quiz is worth 10 points and your top six quiz scores are counted for a total of 60 points in the class. Exams: There will be a midterm and a final exam. Both exams are computerized and proctored. You must arrange an acceptable proctor. More information about proctors can be found below-please see Proctor Policy. A 3 by 5 note-card, with your notes on both sides, may be utilized on both the midterm and final exam. Each exam will have a 2-hour time limit. You will have one attempt on each exam; be sure to save your work often. The midterm exam will be open from 8:00 a.m. Tuesday until midnight Saturday of Week 4. The final exam will be open from 8:00 a.m. Tuesday until midnight Saturday of Week 8. The midterm and final exams are multiple-choice and computer graded. Your percentage is recorded in the D2L gradebook. Each exam is tailored to the learning objectives of the course. There will be an exam review for each exam. You may take them an unlimited number of times to practice for the actual midterm and final exams.
