Lately I have encountered the (exciting) challenge of having to understand and apply more difficult concepts in statistics for the Molecular Techniques in Life Science (MTLS) second year courses. Statistics can be difficult and incomprehensible at times, but that should never stop you from digging into them 😀 After many, many hours looking in the endless Google universe for tips, tricks and understandable explanations I have found some resources which really helped. Because sharing is caring, I have created this post with 5 very useful materials for when you need to get your stats together!
1 – StatQuest
StatQuest is a youtube channel created by Josh Starmer, assistant professor at UNC – Chapel Hill. His videos explain concepts in statistics and machine learning for biologists and include both theoretical explanations and practical examples on how to use them in the daily lab work.
You can check the videos here. My favourite is the one about PCA (super easy to understand!)
2 – Statistical Inference for data science, by Brian Caffo
If you feel you need something more similar to a “real-life” lecture, you can try this Coursera course: Statistical Inference. Taught by Brian Caffo, a biostatistics Professor at John Hopkins University, the course is easy to follow and full of examples.
There is also a book based on this course. The book and other very useful materials can be found at Brian Caffo’s github page.
And if you feel like taking the whole Coursera course is too much you can always watch the specific lecture you’re interested in in his yotube channel.
If Caffo’s course has opened your statistical appetite I have good news for you! There is a whole series of data science courses by John Hopkins University that you can do in Coursera. It is a very complete series, which goes from the very basics to reproducible research, statistical inference and regression models and even machine learning!
3 – Harvard X Biomedical Data Science Open Online Training
The Harvard X Biomedical Data Science Open Online Training is a series of three MOOCs created by Rafael Irizarry, JP Onnela, Vince Carey, Mike Love and Shirley Liu. It contains three courses:
- Data Analysis for the Life Sciences
- Genomics Data Analysis
- Using Python for Research
I have tried the Data Analysis for the Life Sciences course, which is also available in EdX. It contains basic training about biostatistics and what I love about it is that it allows the students to do real-world data analysis using the programming language R. It is very straightforward to follow, with lots of examples, and many solved codes for when you are stuck with the programming part of statistics.
The three courses can be accesses though Irizarry’s github webpage. Each one has a very detailed index about all the topics covered, which makes it very easy to find just what you are looking for without having to complete the whole couse. There are book chapters which can be freely read online, youtube videos and links to the EdX webpage for each of the course sections.
4 – “Points of Significance” from Nature Methods
Points of Significance is a monthly column written in Nature Methods in which essential concepts in statistics and experimental designs for biologists. The articles are 1 or 2 pages long, and give a high-level overview of a statistical method in the context of biological research.
5 – Cross validated
Cross Validated is an oline forum in which people ask their questions about statistics and the online community replies to them. Although you have to always be critical when reading this type of information, most of the answers are high-quality and very reliable. However, these resources are great for solving very specific questions that are blocking you from finishing that Master’s Thesis data analysis. Also, the chances that other people have had the same questions you have and dared to ask them online are quite high! So it just takes a few minutes to get the answer to that question that is keeping you awake at night 😉
