A collection of resources for experimentation

Experimentation Resources

This is a list of resources that I found useful when studying for experimentation based data science roles. It is by no means an exhaustive list, please feel free to message me or submit a PR if you think the organization could be improved or I've omitted any outstanding examples.

Inspired by Dustin Tran's ML Video repo and PhD qual's lists.
