This was the best explanation regarding this topic! Dr. Galak explained it so well in a manner that makes sense and sticks; his intuitive explanation allows me to use this logic and apply it any question on the USMLE step 1 exam regarding this concept. Thank you so much!

The intuition that you provided in the beginning was exactly the piece I was missing to solve this cryptic p value puzzle! Thank you so much, please never stop teaching.

Ph.D. candidate (second doctorate): Outstanding, sir! The easiest (best) description that I have ever read or watched. I feel more confident in my comments about p and H0. Thank you for not getting into the "weeds!" That is where most of us get lost, and the jargon only makes it worse.

Okay so I understood that the bigger the number the weaker the evidence and truer to the null hypothesis. The pace, clarity and preserving the material to basics is SUPER FREAKING supportive of a growth mindset as an adult learner.

Thanks for your explanation. You clarified the concept in plain English. I saw in another video how in Statistics significance has nothing to do with big and important. Something can be small or unimportant but still be "statistically significant."

This is the best explanation to statistical significant studies. Even a grade student will understand this. Thanks Dr.

Took me 50 minutes to thoroughly go through this video and take notes for my AP psych test. Speaking of it, HOW IS THIS AP PSYCH

I’m really glad you found the video informative!

Thanks so much. Very useful video!

Clear explanation, Indeed! Thank you! An area where I feel a “black box magic” happening, that would hope you can explain clearly is: in random permutation tests, data is shuffled randomly from both groups, some (less then factorial for practical purposes, yet sufficient ) number of times, and the subtracted means result makes a normal disturb plot. Now, we know: garbage in-garbage out. The randomization and permutations is possible “garbage”, over exposed and shafted with the original data from the 2 groups. Now, what I feel is magic, I’m supposed to believe, and come to conclusion for validation or rejection of the Ho, based on that original data, from Groups 1 and 2, when mixed with “garbage” to actually retain some of its qualities(or dilute them if it doesn’t) , through the random shuffled permutations, and if it has retained sufficiently( or diluted sufficiently) show me a P value that will disclose strong or weak tendency toward rejecting or accepting the Ho. So , basically, we use the random permutations, as if, analogizing, as if we could use some substance, and say it has those features, and then we mix it with “all kinds of “garbage tests” and eventually are able to say: see, it kept its features, through all those substantive permutations, must be strong, or, you see, it got diluted so much that lost those features, must be not enough strong, what you saw as feature was random feature case, so we keep the Ho. Something like that? Thanks a million- if you can touch upon this theme!
