1 STA569 Applied (Nursing) Statistical Methods Instructor/ Facilitator: Mark A. Gebert MDS 347 (Lexington campus address) Secondary Instructor: Pamela Lancaster * is, easily, preferred method of contact. s sent during regular business hours (M F, 8 5) will be answered by the end of the day unless I ve announced special circumstances (such as the instructor s trip to Shanghai in late June, during which Ms. Lancaster, the TA, and the department chair, Dr. Stromberg, are all able substitutes). This also how any virtual (online or via phone) office hours will be conducted should a problem, either with the material or administrative prove too involved to be solved via , we (the instructor and the student) will find a mutually convenient time to communicate via online means or phone so that the problem is worked out to the student s satisfaction. Text: Agresti and Franklin., Statistics: The Art and Science of Learning from Data. 2 nd Ed.* with MyLab access (bundled with the text typically less expensive); course ID: gebert *Second, not the new and more expensive third, edition otherwise you won t be able to do the homework (and it will cost more money, and the problems won t match, and ) Technology Requirements: In order to participate in this course, you will need access to a computer with the minimum hardware, software and internet configuration described at this site: : s.aspx Note: the use of Internet Explorer is NOT recommended for use with Blackboard. Firefox is the recommended Internet browser for the course. You can download Mozilla Firefox (free) at this site: US/firefox/upgrade.html You will need to install a number of plugins on your computer. The links to the specific plugins required for this course can be also be found your course. If using a UK computer these plugins should be already installed. To check if your browser has Flash, Adobe Acrobat Reader and QuickTime movie player, click this link: If you do not have these, you can download them from this site. To download Windows Media Player, click this link: Students and faculty can download Microsoft Office Suite (including Word and PowerPoint) from this site:

2 Additional required materials: Calculator ( 1 variable statistics on the package) MyLab (required for course homework; additional study tools and e copy of text can be found there) SPSS access* (not needed until midway through the course) *I say access rather than license, however SPSS licensing is available at no cost to any student of this course by simply requesting it from UK Information/Instructional Technology. Recommended materials: Pallant, Julie, SPSS Survival Manual: A Step by Step Guide to Data Analysis Using SPSS for Windows (Version 15). 3 rd Ed., Course goals: A student s successful completion of this course entails: mastering basic statistical concepts, including those associated with its language, the execution of elementary statistical procedures, and correct interpretation of results. This mastery will be practiced and demonstrated using real world exercises with the assistance of computer software both specific to the field, such as SPSS, and generally available and applicable, such as Microsoft Excel. Course grading: Your course grade will be calculated based on the following components: Homework 30% Instructor/TA guided Exercises ( Labs ) 10% Tests (Exam 1 no later than 7/5, Exam 2 no later than 8/1; each worth 30%) 60% Graduate grading scale: , A; 80 < 909, B; 70 < 80, C; <70, E. Undergraduate grading scale: , A; 70 < 85, B; 55 < 70, C; 40 < 55, D; <40, E; and will be based on one fewer homework and lab. Regarding assessment of learning outcomes: homework is viewed and submitted in the MyStatLab online course software. The lab worksheets are generally Word documents downloaded, completed by the student and ed to the instructor. The portion of the grade that cannot be made identical is participation, and this ties into making the conveyance of the material for the distance learning student comparable to that of a classroom based student: lectures, both for classroom and lab material, will be PowerPoint based, with narration/included handwritten examples to augment student understanding, just as would be done using a document camera in the classroom. However, to meet the distance learning students need, these will be posted on the University of Kentucky s Blackboard system in a Flash video format for viewing at the students convenience.

3 Academic Integrity Policy Students are not forbidden (in fact, are encouraged) from collaboration on any exercises other than examinations. Regarding examinations, students will be in communication with Ms. Lancaster regarding finding an approved proctoring site and doing so with enough time to spare that logistics may be put in place for the student to take the course s two exams. Failure to find a satisfactory proctor by the required date will be grounds for a 0 (zero) for the first (and subsequent) exam. The University of Kentucky s Academic offense policy may be found here: Student Services Available The Teaching and Academic Support Center (TASC) website ( offers additional information and resources that can promote a successful online course learning experience. They may also be reached at If you experience technical difficulties with accessing course materials, the Customer Service Center may be able to assist you. You may reach them at HELP (4357) or by e mail at helpdesk@uky.edu. Please also inform the course instructor when you are having technical difficulties. Contact information for Distance Learning Library Services: If you have worked (or tried to work) with all three of these entities and are still unable to gain access to any portion of the course, contact me at mark.gebert@uky.edu and I will begin work on my end to help you. If you have a documented disability that requires academic accomodations in this course, please make your request to the University Disability Resource Center. The Center will require current disability documentation. When accomodations are approved, the Center will provide me with a Letter of Accomodation which details the recommended accomodations. Contact the Disability Resource Center, Jake Karnes, Director at or jkarnes@ .uky.edu.
