Recently I highlighted a decision tree tool for experimental design. EDA, or Experimental Design Assistant, helps you to plan your experiment, choose the approrpiate groups and numbers you’ll need. Set some variables, etc. This week’s video also offers decision trees–but these help you to evaluate the data from your studies of interest instead. Branch is a web-based tool to help you test your hypotheses and develop models using data that’s available in a given data collection.
There’s a paper (linked below) with the backstory and information about how the tool works. But they’ve also done a nice series of videos to show you how to interact with the tools. The first one will be this week’s Video Tip of the Week. But be sure to check out the other ones for additional features as well. Each video tackles different aspects of the functionality that will help you to get the most from your explorations.
Try it out. You can use existing examples, or include your own data. You can make your own data private, or make it available to share with others. Be sure to read their disclaimers and think carefully if you are using certain data sets that have privacy issues. But there are probably many publicly available data sets that could get you exploring some hypothesis around your topic of interest.
Hat tip to the author whose tweet sent me looking to investigate this:
