StatQuest should be mentioned in my future Data Scientist Master Diploma. Seriously! Every time I get introduced to a new concept, I come here and.. BAM! it all makes sense.

Having trained myself on other StatQuest video, I predicted that I would understand this video and I actually understood this video, so that looks like a True Positive right there.

Your channel is honestly gold... I used to think stats is a mystery and it didn't make intuitive sense until I met your channel - now everything makes sense and I enjoy using them. Thank you for making these free and accessible, I really appreciate your effort, dedication and intelligence

Your videos are always astoundingly clear and well explained! In fact, you've inspired me to the point of being the first YouTuber I support financially!
