Video Tutorials

Video tutorials are a great way to learn. You can watch these videos at your own pace and view them as often as you need. The tutorials include a substantial lecture, introducing biostatistics using the R language. There are also video lectures on data visualisation. There are even lectures on less often used, but very important statistical tests such as the Hotelling’s test and G tests. Check back often for new lectures.
