Course Description This course will provide you with an introduction to descriptive and inferential statistical methods to inform health care organizations’ operations and strategic planning functions. II. Course Prerequisites Although this course does not have any formal prerequisites, it is important that you are comfortable with mathematics (including basic algebra), as well as Microsoft Excel 2007 or 2010, PowerPoint 2007 or 2010, and Word 2007 or 2010. The course does not assume any prior training in statistics. However, given that this is a graduate-level course, the material will be presented at a faster pace and in greater depth than a comparable undergraduate course. III. Course Goals and Objectives To recognize the value of data-based decision-making in health care organizations. To identify and interpret patterns in raw data using both graphical and non-graphical methods. To understand fundamental probability concepts and their relationship to inferential statistical methods. To perform inferential statistical analyses, including hypothesis testing and confidence interval construction and to be able to interpret results in the context of prevalent issues in health care management. To understand the fundamentals of regression analysis and to accurately interpret model results. To apply regression analysis tools for predictive modeling and forecasting of continuous and discrete outcomes in health care. To use Excel-based software to conduct analyses with population-based and organization-based health care data. Spring 2013 1 IV. Methods of Instruction and Work Expectations The course is divided up into multi-week modules and is organized in such a way as to provide additional flexibility to students who need to balance their studies with other work and life responsibilities. Each module utilizes a variety of instructional methods, including: Voice-over PowerPoint presentations Camtasia Relay video presentations Text and handout readings Self-study exercises and suggested answers Excel-based practice exercises and suggested answers Excel-based assignments This is a rigorous, graduate-level course. You should plan to spend 8-10 hours per week, on average, to achieve mastery of the material. The amount of time spent on this course is typically related to a student’s prior foundation in statistics and quantitative methods. This is an asynchronous online course with one orientation session. V. Course Text, Lessons, Readings, Problem Sets, Software, and Supplemental Materials. Required Textbook: Albright, Winston and Zappe, Data Analysis and Decision Making – Fourth Edition, South-western Cengage Learning, 2011. Readings: Textbook and other readings will be assigned. PowerPoint: Each module will include one or more lessons. Lesson notes corresponding to the presentations also will be provided for reference. Problems: Mastery of statistics and quantitative methods requires practice. Each week, selfstudy exercises, Excel applications, and suggested answers will be posted. These problems will not be turned in for a grade. Statistical Software: Excel 2007/2010 will be used. This course also uses the student version of the DecisionTools® Suite that comes with the textbook. The StatTools component of the suite will be used. Instruction for using “traditional” Excel will be integrated into modules and exercises throughout the semester. Supplemental Materials: Periodically, we will provide links or articles that may be of interest to you. VI. Communications If you have questions regarding course content or assignments, please do not hesitate to contact the instructor or teaching assistant. We will do our best to respond within 24 hours on weekdays and by Monday if you contact us during the weekend. VII. Evaluation and Grading Criteria: The final grade for this course will be determined by performance on four assignments and participation via online discussions. The assignments will include analyses and/or interpretation of data to inform managerial decisions by health care organizations. Assignment 1 (20%) Assignment 2 (25%) Assignment 3 (25%) Assignment 4 (20%) Participation (10%) Spring 2013 2 Assignments may be done individually or in groups of two. No exceptions will be made for collaborations in excess of two students. Assignments are due on the date indicated. Failure to submit an assignment without prior permission of the instructor by the due date will result in a late penalty of 5 percentage points per day. If an assignment is not submitted within one week following the original due date, no credit will be given. Permission to turn work in late without penalty will be granted only for very serious reasons relating to medical emergency or death in family, etc. Please plan accordingly. Participation will be evaluated based on posting to the online discussion forum during the semester. For most modules, an issue and question(s) will be raised by the instructor. Students will be asked to reflect on the issue or question(s) and to provide a thoughtful response for at least two modules. The issue or question(s) may be motivated by a recently published piece of research or an organizational case study, and may also ask you to reflect on your own experiences as they relate to the specific topic. Grading Scale: An A/F letter grade will be determined based on the following: A=93-100% Represents outstanding achievement relative to the level necessary to meet course requirements A- = 90-92.99% B+ = 87-89.00% B = 83-86.99% Represents achievement that is significantly above the level necessary to meet course requirements B- = 80-82.99% C+ = 77-79.99% C = 73-76.99% Represents achievement that meets the minimum course requirements C- = 70-72.99% D+ = 65-69.99% D = 60-64.99% F = < 59.99% No credit. Signifies work was below level of achievement that represents minimum threshold to obtain credit or work was not completed and there was no agreement between instructor and student that the student would be awarded an I.

VIII. Course Evaluation Beginning in fall 2008, the SPH collects student course evaluations electronically using a software system called CoursEval: www.sph.umn.edu/courseval. The system sends email notifications to students when they can access and complete their course evaluations. Students who complete their course evaluations promptly can access their final grades just as soon as the faculty member renders the grade in SPHGrades: www.sph.umn.edu/grades. All students will have access to their final grades through OneStop two weeks after the last day of the semester regardless of whether they completed their course evaluation or not. Student feedback on course content and faculty teaching skills are an important means for improving our work. Please take the time to complete a course evaluation for each of the courses for which you are registered. Incomplete Contracts A grade of incomplete “I” shall be assigned at the discretion of the instructor when, due to extraordinary circumstances (e.g., documented illness or hospitalization, death in family, etc.), the student was prevented from completing the work of the course on time. The assignment of an “I” requires that a contract be initiated and completed by the student before the last official day of class, and signed by both the student and instructor. If an incomplete is deemed appropriate by the instructor, the student in consultation with the instructor, will specify the time and manner in which the student will complete course requirements. Extension for completion of the work will not exceed one year (or earlier if designated by the student’s college). For more information and to initiate an incomplete contract, students should go to SPHGrades at: www.sph.umn.edu/grades. IX. Other Course Information and Policies Course Withdrawal Students should refer to the Refund and Drop/Add Deadlines for the particular term at onestop.umn.edu for information and deadlines for withdrawing from a course. As a courtesy, students should notify their instructor and, if applicable, advisor of their intent to withdraw. Students wishing to withdraw from a course after the noted final deadline for a particular term must contact the School of Public Health Student Services Center at [email protected] for further information.
