Prerequisite MATH 182 and a 200-level math course. Course Description/Objectives This course is an introduction to statistical concepts and methodology. Topics covered will include data collection, graphical and numerical summary techniques, basic probability, discrete random variables, continuous random variables, central limit theorem, confidence intervals, hypothesis testing of a proportion, hypothesis testing of a mean, two-sample hypothesis testing, chi square testing, and regression. Course Objectives Upon completion of this course, students will become proficient in summarizing data both graphically and numerically understand reliable and unreliable means of collecting data comprehending the concept of sampling variability constructing and interpreting confidence intervals conducting tests of inference understanding the concept of statistical significance analyzing relationships between variables using computer technology for statistical graphs and calculations Methods of Assessment Homework 20% Exams 60% Quizzes 20% Grading Course average Grade Course average Grade 92.0-100% 90.0-91.9 88.0-89.9 82-87.9 80.0-81.9 A AB+ B B- 78.0-79.9 70-77.9 60-69.9 0-59.9 C+ C D F Course Requirements Quizzes: There will be in-class quizzes that cover the most recent class material. Quizzes will be announced one class day ahead. You will be able to work in a group to collaborate on quizzes. The maximum number of students in a group is 3 and no notes or book is permitted. If you miss a quiz you are responsible to make arrangements to make it up. Exams: There will be three comprehensive exams during the semester. Tentative dates for the exams are listed on the course calendar. Final exam date is also listed on the course calendar. Exams will be in-class, based on material from class and the textbook, and are open-book, open-notes tests. You are responsible for all material covered in class. For the exams, software will not be required, but output may need to be interpreted. A calculator will be needed. Cell phone calculators will not be permitted for use on exams. Homework assignments: There will be weekly homework assignments from the textbook. It is important to do all of the assigned problems in order to learn the material and do well on the quizzes and exams. Homework will be graded for completeness, however incorrect problems should be reviewed. Late homework will be accepted, but 10% will be deducted for each class period after the due date. Class Conduct Please bring your scientific calculator to each class. Cell phones should be turned off or placed on vibrate. Text messaging during class is not appropriate and grounds for removal from class. During computer lab sessions, checking email and surfing the web is inappropriate. If you are late to class or leave early, please do so with minimal disruption to the classroom environment. Attendance There is a direct correlation between success in the post-secondary classroom and consistent class attendance. If you miss a class, it is your responsibility to cover the material from that class. Attendance will be taken into consideration for borderline final grade assignments. In general, there are no make-up or retake exams. A make-up exam will only be permitted in the case of a proven emergency (i.e. documentation can be produced to validate the emergency) or if arrangements have been made with the instructor before the original date of the exam. The final exam cannot be made up. Technology Blackboard: Data files, guided notes, slides, and other resources will be posted to Blackboard. Calculator: Each student will need a scientific calculator (TI 84/83 is recommended) for class and exams. Bring your calculator to each class meeting. Cell phone calculators will not be permitted for use on exams. Software: We will be using the software that accompanies the text, Statkey. You can access the software at http://lock5stat.com/statkey/index.html Minitab which can be installed using Blackboard will also be used.

Disabilities Statement Students with disabilities which may affect their ability to complete course requirements in this class may request appropriate accommodations by registering with the Office of Disability Services at (216) 687-2015 in Main Classroom 147 and discussing the nature of their situation. (http://www.csuohio.edu/offices/disability/) Retention of Graded Work I strongly suggest that students retain all graded work from the course until the end of the semester and final grades are posted. This way if a discrepancy arises between a recorded grade and the actual grade, we have the actual document to examine in order to rectify the situation. Additionally, graded work makes for excellent study materials for upcoming exams.
