How to calculate p-values
StatQuest with Josh Starmer
@statquestAbout
Statistics, Machine Learning, Data Science, and AI seem like very scary topics, but since each technique is really just a combination of small and simple steps, they are actually quite simple. My goal with StatQuest is to break down the major methodologies into easy-to-understand pieces. That said, I don't dumb down the material. Instead, I build up your understanding so that you are smarter. Contact, Video Index, Etc: https://statquest.org
Video Description
In this StatQuest we learn how to calculate p-values using both discrete data (like coin tosses) and continuous data (like height measurements). At the end, we explain the differences between 1 and 2-sided p-values and why you should avoid 1-sided p-values if possible. NOTE: This StatQuest assumes that you are already familiar with what p-values are and how to interpret them. If not, check out the quest: p-values: What they are and how to interpret them.
