The goal of this course is to help students to prepare for thesis writing or making their own student research project. It covers two fields of that job: the practice of data collection and prepare data for the analysis as well as the performing the analysis based on the preliminary analysis plan. Shortly to say: How to perform the data collection and analysis of your own study project. (This course can be the continuation of the ‘Data analysis 1’ course however someone can complete these two courses on a reversed order as well. The main reason of this flexibility is, that many students are asking for help when they have already had their data at hands (at least partially), and this course is processing the steps from this point of the job. Even though, it is beneficial for the students doing this course first to complete the Data analysis 1 course later. They can do it next year for example – so to understand the preliminary steps of a research work: How to make a research plan?)
This course is also based on the medical papers. Students may pick the appropriate data collection methods and recognize the critical points of this process based on the most fundamental papers of their own research field. They can learn from the most rewarded experts on this way. From a paper you may extract the principles as well as you can follow immediately the realization. It is an excellent way to learn the methodology. You may even learn from the errors.
The same way is followed for the data analysis and making conclusions. Every student will do his/her own data analysis based on their own plan.
Students will have all help to the practical evaluation of their own data and making the right conclusion. The steps and results will be discussed and improved by a class discussion.
