[@InaKatsCanne]

can't thank you enough! one of the only videos out there that puts it in a health services research/biostats context, appreciate it!

[@hit4success]

this is the video tutorial where my concept has been cleared on P-value, TYPE I & II error, Level of significance, and 3 Test. Thank for sharing the video.

[@pumpkinpie025]

Hi there, I'm completing a research class in my NP curriculum and you've pretty much summed up 3 chapters in a nicely explained 16 min. video. Honestly, statistics is such an abstract topic, but you've managed to clearly explain and correlate concepts in a very logical and understandable way. I will be referencing your video in some of my discussion boards. Thanks for taking the time to put this together. Great job!

[@jluqas]

I can’t thank you enough for this exceptional video. All the doubts in my mind about p-value, statistical significance and the Ho cleared. You are god sent!

[@bikegirl649]

With much gratitude, I thank you for succinctly explaining p-values, stat significance. I've been struggling for days and am thankful this video popped up in my feed.

[@cait7140]

Realized I failed my stats midterm because I didn’t properly understand these key concepts. This video clarified so much! Hopefully the next midterm goes better. Thank you for your clear, concise explanations

[@taurahdizadare8238]

Thank you so much for breaking biostats down in a much simpler way for me to understand. I have my exam in 3 weeks and was freaking out terribly behind these concepts. You're a lifesaver!

[@leahjaelgreen]

Cannot thank you enough I have been struggling with this for two days. Taking online statistics is a bad idea, but you made it very logical and now I understand. Thank you thank you thank you! ❤️

[@chung-han]

You really saved me. you cleared almost all of my confusion this whole semester with this video alone, would like to see more research statistics explanations like this one.

[@coventrykids9795]

Literally the best video-tutorial on methodology that I have come across so far! Thank You!

[@saratrejo7271]

This video was great to build a foundation to understand statistical hypothesis. Thank you!!

[@ryanmaki323]

Thanks for the explanation! you made it way more simple for me to interpret the differences in p-value and alpha in my data from my 1st ANOVA study I did for school.

[@fundeadwarrior]

Explained in a clear, simple and sequential manner. This man is an artist!

[@kendallshaw1154]

You just explained in 15 minutes what my professor couldn't get across in 6 hours of lecturing. Posting this link to my class discussion forum!

[@amieparsons5110]

This is great! I am in mental health and the way you explained it in clinical terms was so helpful! I will be passing this on to my son as he will be attending med school soon. Thank you!

[@joeeesim3281]

I watched at tons of video prior to this and still not sure what is going on, until I found this. Thank You! much appreciated!

[@BadlndsBob]

Very informative video. I had this in grad school a LONG time ago and this was a good refresher. It helps me to be certain of how poorly informed (ignorant) some folks I know are.

[@leetabgolden]

LOVE your videos! you are so good at breaking it down and giving us examples to make this stick!

[@ianluckhurst2709]

very nice! I'm struggling with stats basics for my masters program and this was great for me to understand some of the important things.

[@CesarFelipeLopez]

Came here after jumping around some videos looking to clarify what the P-value was. Thanks for the easy explanations.

[@gwendolyngaines3016]

OMG!!!! Where have you been! You just simplified the Null and Type 1 and 2 Error! THANK YOU. I have placed you in my favorites!!!! Keep up the great work for people like me. :)

[@chenburnett]

Jesus！So far, the most explicit but in a simplest way to explain these difficult stuff which enables me finally start to understand more about all these tough concepts！Thanks!

[@pamgarat2056]

Thank you. I missed a week of school and have felt lost since. Your explanation was great and I will be watching it a couple more times.

[@ranrana3]

I do appreciate your hard work! Your video helped me a lot, especially when it comes to rejecting and fail to reject the thanks hypothesis

[@ozgurtekcan8304]

It is probably the best video explaining Null Hypothesis, P Value and their interaction plainly. Great Work!! Many Thanks

[@davidking9328]

I'm highly grateful for this video. I finally understand p-value and stat significance. You have done a tremendous job brother, God bless 😊🙏🏾

[@summayaasmat1856]

U made it so simple thanks sir...i watched many videos before but they jst confused me even more....this one really helped me👍

[@shabareentisha787]

Thanks a lot for your great effort. This is one of the best lectures that I've ever watched.

[@nathaniel6975]

Thank you ...you saved me almost a week to exams and I am now getting the concepts

[@wandag1311]

Thank you! This helped in a much clearer fashion! I don't know why people can't explain this stuff simply for those of us who aren't trying to become a statistician.

[@thechocolatedoc1]

Thank you for making this information clear and understandable! I appreciated watching it.

[@cherylhoward8567]

This video really helped me understand these concepts better. Thank you for the clarity!

Thank you, great video! In preparation for my Certified Quality Engineer exam, this video helped break down the details to nice digestible levels.

[@alicefreegard8241]

really helpful thank you! The realistic examples really helped too. I find it so challenging to understand this topic when reading from a text book

[@meeral8703]

Thank you for making this so clear! The real MVP!

[@thejojoproductions2532]

Thank you for this amazing video! I had sat in on my stats lecture a few weeks back and was mildly panicking because I didn’t understand Type I/II errors and why alphas and betas were popping up. I’ve understood more in this 15 minute video than in my whole 2.5 hour stats lecture.

[@justinmahoro3687]

This is very helpful. The last summary you did about which test to perform it was very important.

[@andotech]

This is crystal-clear. Thank you! A lot of us are using this for machine learning to hasten the Technological Singularity. Make sure you're all paying attention and keeping your politicians in check! This can turn out to be a utopia or a nightmare for humanity. Good luck, everyone, and I'll see you on the other side!

[@wahjmohamedkhair8018]

Ever heard of - Fellmeroni Rudimentary Chi - (just google it ) ? Ive heard some interesting things about it and my work buddy got excellent success with it.

[@naveenswarnkar4180]

Your awareness save academically! Please never stop to love yourself because no one like you on this planet earth! Please watch Being friend yourself by Nidedita Thomos TED Talk"

[@jenniferramos9967]

this video clarified all these concepts for me, thank you very much!!

[@genevieveutley807]

Wonderful, thank you for posting this video. You made this material understandable and accessible.

[@Katie-ic4fx]

You must know that I spent a whole 5week period trying to understand these concepts, getting overly frustrated because none would explain this in a crystal manner as you did. Finally, I get it. Tutors like you are worth receiving funds to get this presented elaborately as you just did here. my goodness, I'm liberated!!!!!!!!! Thank you a mammoth!

[@gabrielleassemian5154]

Very helpful for beginners you explain it with simple words which makes the difference. Thank you for using the correct type of communication which is SIMPLE WORDS and giving examples right away helps understand the material a lot. Thank you.

[@MultiSomali]

Yes! I finally get it, thank you this video it has clarified so much for me.

[@jayeshbagul6643]

Explained very conceptually. Nice work. Thank you.

[@marcequintero9768]

Thank you very much for this. It's very useful. No studying in the US but statistics are, of course, the same everywhere, and exams likely ask similar questions. Keep it up :)

[@harshmalik3470]

The greatest explanation ever to these topics. Thankyou so much!

[@nithinthesedays]

This really helped me in my report. I am relatively new to statistics and p-testing but this was really helpful.

Your videos helped me straighten out a semester's worth of statistics; I definitely feel like I have the terms more organized and I'll be better prepared for my exam today

[@angelaolton467]

Hi there...really enjoyed the video and helped me in understanding these concepts better, so thank you! I clicked on the black box in the end (watching from computer), but it does not go to another video, it only pauses and plays the current video. Thank you again for this great tutorial!

[@shayekhabedin4462]

the moment i started watching the video - you made me feel so good by calling me a distinguished physician, tysm

[@elizabethb60]

[@javid659]

Understood things make easier to understand others...I am very thankful to him for such a nice presentation. But one thing which I am unable to hear correctly is the name of two groups when compared. If any one please write the two groups being compared...

[@erikafleming2872]

A thought for future iterations of this/this type of video: When using values to exemplify what you're describing, it would help the viewer to see those values on the screen. I had to re-watch so I could write down the values to see what you meant/prove it out with you.
