NURS 701 – Biostatistical Methods for Health Care …



STAT 601 – Statistical Methods for Health Care ResearchSummer Session 2018This handout covers basic information about the course. It contains the tentative course syllabus, information about my website, and the D2L website. It also briefly discusses technology for hosting online meetings.COURSE INFORMATIONInstructor:? Brant Deppa, Ph.D.Office:? 124 B - Gildemeister Hall (Winona Campus)Office Hours:? It is best to contact me via e-mail and arrange a time we could meet using Breeze, Skype, or a chat on the phone.Phone:? 507-457-5457e-mail:? bdeppa@winona.eduWebsite: course1.winona.edu/bdeppa Courses STAT 601COURSE DESCRIPTIONWe will review most of the common statistical methods, research designs, and data procedures used in health care research.? With the emphasis in health care today on evidence-based practice, it is more important than ever for health care professionals to understand essential information about measurement, sampling, and statistical analysis techniques.? The topics covered in this course represent basic tools most commonly employed in the published literature in the health sciences.A second important component of the course will be conducting statistical analyses yourself using a statistical software package. The package we will be using is SAS-JMP 13 Pro because it is my experience that it is by the far the easiest statistical software to use. It also is very visual which I believe makes it easier to “see” the important features of data. On most assignments you will be using actual data from published studies to conduct appropriate statistical analyses using JMP and then interpret the results from them to answer research questions of interest.? Required Materials: 1) JMP 13 (it may be JMP 14) Pro which you can download for free. You should all receive an e-mail from Steve Heftman which contains a link you can use to download JMP 13 Pro. I will send out an e-mail when I knoe you should have received it. If you do not receive the e-mail with link to download JMP 13, please contact Steve Heftman (sheftman@winona.edu). 2) A computer should also be capable of viewing lecture materials and running JMP 13. If you are having troubles with the lecture video (typically problems with audio) try refreshing your browser a few times. I use Google Chrome generally, but Mozilla Firefox or Safari should probably work fine as well. Students tend to have the most problems with Internet Explorer. I have never had a student who ultimately was unable to view the lecture materials.Optional/References (in order of importance):Basic Biostatistics: Statistics for Public Health Practice, Jones and Bartlett, by B. Burt GerstmanBiostatistics: A Foundation for the Health Science (9th or 10th ed.), Wiley Publishing by Wayne Daniels. These texts are not required and do not follow either one per se, but the content covered in the course is found in both of these texts.Evaluation: Course assignments & projects100%Course grades will be assigned as follows: A = 92%-100%, B = 82%-91.99%, C = 72%-81.99%, D = 62% - 71.99%, F = below 62%Assignments will consist of: Viewing all relevant lectures and software pletion of assigned problems. Some of these problems will consist of answering questions pertaining to a research paper related to the current course topics. The other problems will require conducting statistical analyses in JMP using real data and answering questions related to the results.? All relevant computer output should be incorporated into your write-ups.? This is easily done by copying output and pasting it into Word.You are allowed/encouraged to work in groups of two (or possibly three) on the assignments. You need only submit ONE copy of the assignment but make sure that both group members names are at the top of the assignment! If you prefer to work alone, you are certainly welcome to.
