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! ❤️

[@Goldpoint3295]

Most explanations of P-Value on KZbin are not clear at all. Some do not include the alpha threshold for the interpretation of the P-value. They also explain that the 5% shows that there is only a 5% chance of rejecting the null hypothesis. This is the best and clearer explanation out there❤

[@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.

[@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!

[@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.

[@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!

[@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

[@ngotranhoanhson5987]

wait, if you failed midterm, you failed the whole subject?

[@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!

[@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!

[@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.

[@nathaniel6975]

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

[@CesarFelipeLopez]

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

[@shayekhabedin4462]

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

[@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!

[@fundeadwarrior]

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

[@oluwatobilobamayadenu6261]

One million years for you o..u've helped me a lot now in understanding my course

[@rebeccatheurich6397]

thanks, u are far far better than my lecturer in school. i truly am grateful

[@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!

[@coventrykids9795]

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

[@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!

[@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!

[@ozgurtekcan8304]

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

[@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!

[@millionairedee6136]

This was by far the best explanation of pvalue for me.

[@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.

[@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.

[@narminmusayeva6082]

Perfect explanation. Finally understood the p-value. Thank you!

[@seidwodajo3499]

Wowww What a clear explanation. That is the reason why I love KZbin!

[@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.

[@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. :)

[@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.

[@mmagat1]

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

[@lazarusw9297]

Thank you, your explanation is very easy to follow. I may have learned more from you than my current teacher.

[@harshmalik3470]

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

[@saratrejo7271]

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

[@shobhamandal982]

this is the first time understood sir..thank you

[@stomponstep1989]

+Shobha Mandal thanks for the comment and feedback Shobha! I'm glad the video helped

[@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.

[@dishsoap6996]

So to confirm about the a and p value does it mean that when p>a, the chances that the extreme results in the collected data set is more likely of type I error and not due to the tested variable and thus there is no significant difference, and when p

[@gurpreetsinghdhanjal2089]

Very well explained......I went from confusion to clarity really fast! Thank you!!! :)

[@kaviranganza2875]

Thank you for helping me to understand this point of the significance of Hypothesis testing. The video is helpful.

[@mansi1244]

After a long research I got ur video ..it’s very useful

[@someperson8035]

very helpful! I am a first semester nursing student and we are learning statistics for evidence based practice. Thanks

[@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!

[@steftheengie2904]

i have a stats exam in 8 hours. i love you profusely.

[@oscarwilde399]

One thing that I would point out is that a p > 0.05 DOES NOT mean that there is "no statistically significant difference" (see 10:09). It only means that we cannot tell if there is a statistically significant difference.

[@mildredakandinda6574]

very interesting I have been hearing those terms was being disturbed in understanding, but now iam coming up. Thank you so much

[@aikiistifanus8067]

Lightens up some of the grey areas i was facing in Statistics. Thanks.

[@felixkulelogo7738]

THIS IS SUPER TO SOME OF US THE BEGINNERS IN BUILDING A FOUNDATION IN STATISTICS

[@danahmohammad8269]

thank you you've helped me a lot , now i just understood the whole concept

[@nadiayvonnerazanajao7082]

Cheers for this, I been tryin to find out about "learning powerful methods to build your Chi energy" for a while now, and I think this has helped. 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.

[@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.

[@MrCompenso]

THANK YOU, you have no idea how unqualified my teacher is for this subject.

[@dr.senthilvadivelmurugaiya3550]

You are highly realistic. After my retirement I have completed my Ph.D only with the you tube statistics. I think you want to learn more statistics. My revered you tube professors are Pat Obai, Toad Grande, Balasubramaniam you also refer them. My blesses

[@stevengreen3156]

Thank you for the explanations in this video. I have an Epidemiology exam tomorrow and the information in this video has helped me greatly.

[@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...

[@justinmahoro3687]

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

[@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.

[@LuisCamacho-ql5so]

Best explanation on KZbin

[@innocentiaerdogan7408]

I am a PhD student I must say this helped a lot. Thank you Sir.

[@mukwevho01]

the best explanation ever. not abstruse at all!

[@stomponstep1989]

+lin duncan thanks for the comment Lin!

[@reconshunter]

I still have issues understanding the p-value. If it is, as you said 7:02 then having a high p-value, therefore a high probability that we will again get a difference of 20 between the two groups, would that no indicate, that there is a difference and therefore the groups are not the same? Why does a low probability for a difference indicates that they're not the same?

[@dmmath-tutor5769]

Excellent video. I like your style of presentation.

[@cherylhoward8567]

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

good video and direct; the p -value is seem to be irrelevant unless we able to see use anova to check on F value, F Critical value to conclude ?

Very broad, very deep, very mountainously great method of teaching...reminds me of the song River Deep, Mountain High

[@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

[@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 :)

[@brendapoole8490]

This video was very helpful. I really understand the different approach to testing. Thanks for your expertise.

[@janp.2901]

You are good in explaining this topic.

[@cadhorreecagoureec9678]

thank you made to understand the use of P-value much better then before

[@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.

[@patriciasanchez7822]

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

Lucid explanation of a complicated topic thank you

[@wahjmohamedkhair8018]

most important information for me was understanding the meaning of p-value, because I thought rejection the null hypothesis meant automatically the alternative , but I can now see that is only a measure of how compatible our data with the null Hypo.
