Biostatistics II  2010 Part II the sequel

This is the last part of the statistical package that you will receive during your study as engineers in health technology and science. The course will contain topics specially related to statistics in health science. Biostatistics is a special branch of statistics and is among other characteristics notorious for:
  1. Complicated experimental designs
  2. Normality is unusual 
  3. Methods specific for Biostatistics
  4. Sometimes very small sample sizes and sometimes very large sample sizes
Biostatistics is still an actively researched branch of statistics, but we will in the course focus on the application aspects of biostatistics. We will therefore use SPSS for computations of some examples. SPSS may not be the best statistical program but it is by far not the worst and we have licenses for it. It can be downloaded and installed from HST net-support. The license is only given to students and staff at HST not all users of emule! We will use SPSS in the last 4 lectures, so please bring you laptop. You may also find the open source program, PSPP, from GNU interesting: It does not seem as extensive as SPSS you may be able to find add-ons somewhere. Thanks to Lars Johannesen for the hint.


This is a course plan.

The course will be evaluated by a written examen together with Biostatistics II part I. Each parts counts one half each. There are some examples of previous examens from this part here. Please note that most (if not all) are in danish as the course was tourght in danish previously, and that the curriculim has changed.
