Chapter 7 Your Own Experiment II
Date: End of the academic year (late June, EBG course)
Topic: Study design, hypothesis testing
Duration: Up to you.
If you’ve completed the rest of the portfolio, you have now used a \(\chi^2\)-test, a \(t\)-test and even simple linear regression at least once. You should also have had your first statistics course by now.
Designing a study is all about performing experiments and collecting their data, such that you can perform an analysis that can satisfactorily answer your research question. Hence, the more you know about statistics, the more complicated questions you are able to tackle.
For the purpose of this project, I recommend that you design your experiments around a technique you are already familiar with. For instance:
- A comparison of frequencies (\(\chi^2\)-test);
- A comparison of two group means (\(t\)-test);
- A comparison of more than two group means (ANOVA);
- Estimating a linear relationship between two continuous variables (simple linear regression).
During the EGB project, I will give a lecture about what to do and what avoid when designing your study. There will also be a Q&A about analyzing your data.
For the biostatistics portfolio, there are no further exercises in this chapter. There will be a statistician among the jury of the project presentations, who will judge the analysis of your experiments and the interpretation of the results.
