can't thank you enough! one of the only videos out there that puts it in a health services research/biostats context, appreciate it!
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.
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!
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
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! ❤️
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.
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!
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!
This video was great to build a foundation to understand statistical hypothesis. Thank you!!
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.
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.
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. :)
Explained in a clear, simple and sequential manner. This man is an artist!
Literally the best video-tutorial on methodology that I have come across so far! Thank You!
LOVE your videos! you are so good at breaking it down and giving us examples to make this stick!
Thanks a lot for your great effort. This is one of the best lectures that I've ever watched.
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
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.
U made it so simple thanks sir...i watched many videos before but they jst confused me even more....this one really helped me👍
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.
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!
Came here after jumping around some videos looking to clarify what the P-value was. Thanks for the easy explanations.
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!
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.
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!
Thank you so much for posting this video! This and your other videos are helping me understand the biostats concepts in my Evidence Based Nursing class!
I'm highly grateful for this video. I finally understand p-value and stat significance. You have done a tremendous job brother, God bless 😊🙏🏾
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.
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.
Thank you ...you saved me almost a week to exams and I am now getting the concepts
It is probably the best video explaining Null Hypothesis, P Value and their interaction plainly. Great Work!! Many Thanks
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
This is very helpful. The last summary you did about which test to perform it was very important.
This video really helped me understand these concepts better. Thank you for the clarity!
Thank you for making this information clear and understandable! I appreciated watching it.
One million years for you o..u've helped me a lot now in understanding my course
Very well-paced and clear explanation of the concepts. Thank you so much!
Thank you, great video! In preparation for my Certified Quality Engineer exam, this video helped break down the details to nice digestible levels.
thank you so much! you are good! concise with all the Important information ! I declare my love for this video, thanks,,,
thank you you've helped me a lot , now i just understood the whole concept
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.
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.
this is the first time understood sir..thank you
+Shobha Mandal thanks for the comment and feedback Shobha! I'm glad the video helped
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!
A huge thanks to the way each concept is explained and it really helped me a lot!
Thank you, your explanation is very easy to follow. I may have learned more from you than my current teacher.
hello, thank you for making things lighter and comprehensible in a nut shell compared to the actual review center discussions which i find it chaotic and informaton overloaded. really big big help in my self studies.. keep up the goodwork guys! you're amazing!
Miss do you know how to calculate
Can u please calculate for me
Tomorrow I have to submit my project i don't know how to calculate I can't focused at all my hands are shaking 😭
I was having a hard time understanding this topic not until u discussed it. You saved me academically, i am beyond grateful.
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"
Clear - actually nearly getting it!! Thanks.
+lin duncan thanks for the comment Lin!
These videos are AWESOME! I am currently working on my MPH and always struggle with p-value and what it means. Thank you for uploading... please continue!!! :)
Very well explained......I went from confusion to clarity really fast! Thank you!!! :)
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
Thank you so much for this video! It has really helped me understand all these different terms and meanings when it comes to reading scientific papers
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.
thanks, u are far far better than my lecturer in school. i truly am grateful
very helpful! I am a first semester nursing student and we are learning statistics for evidence based practice. Thanks
This video was very helpful. I really understand the different approach to testing. Thanks for your expertise.
fantastic video! Learned so much in 15 mins than my hour lecture.
short, concise. more importantly, the information is precise. thanks for sharing your knowledge!
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!
Thanks alot McDaniel, it's a great video, it simplifies what's usually perceived as complicated 🙏🏽
Thank you for making this so clear! The real MVP!
Explained very conceptually. Nice work. Thank you.
Lightens up some of the grey areas i was facing in Statistics. Thanks.
it is my first time learning this chapter and this video really helped me alot. i still need more practice on when to apply the formulas.
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 :)
I’m having trouble figuring out the Levene rest and homogeneity of variance. How do you know if it wasn’t or was violated by looking at the data.
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!
Perfect explanation. Finally understood the p-value. Thank you!
Really helpful! No unneeded information. Thank you!
This really helped me in my report. I am relatively new to statistics and p-testing but this was really helpful.
Thank you so very much, you decrease my pain with these amazing videos.
omg thank you so much! Best video on the topic so far. Very easy to understand.
Thank you very much ! It helped me a lot in preparing for data scientist interview
thank you, this is very well explained. Explaining stats in plain english must be very tricky, eg the constant use of double negatives in explaining stats, eg in explaining type 1 and type 2 errors can lead to misunderstandings.
Thank you! This summarized what I needed perfectly.
After a long research I got ur video ..it’s very useful
The greatest explanation ever to these topics. Thankyou so much!
the moment i started watching the video - you made me feel so good by calling me a distinguished physician, tysm
million thanks, professor! finally, I understand these topics.
Love it!!!!! so clear!!! finally i understood the topic. Thank you
Thank you! You helped me to connect the dots of some basic concepts in statistics!
Wonderful, thank you for posting this video. You made this material understandable and accessible.
Very broad, very deep, very mountainously great method of teaching...reminds me of the song River Deep, Mountain High
Can I use this to compare year over year volumes after an intervention ? ie 2018 volume of CPR compared to 2019 CPR after residents are introduced in 2019?
Thank you sooo much, I finally understood! You were so clear about the topic
This video was very helpful and the clearest explanation I have come across on the topic.
Thank you for helping me to understand this point of the significance of Hypothesis testing.
The video is helpful.
This was by far the best explanation of pvalue for me.
Thank you sir, i was searching for a good video on statistics, helps a lot !!
+Vaisakh Krishnan thanks for the feedback Vaisakh!
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.
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.
very interesting I have been hearing those terms was being disturbed in understanding, but now iam coming up. Thank you so much
this video clarified all these concepts for me, thank you very much!!
Can someone help me out? When we talk about the groups, for eg. that there is a significant difference between two groups when p-value < alpha, are the two groups that we are referring to are the datasets from null hypothesis and the dataset for alternate hypothesis?
Thank you for the explanations in this video. I have an Epidemiology exam tomorrow and the information in this video has helped me greatly.
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...
Thank you for this!! You've explained it more clearly!!
Yes! I finally get it, thank you this video it has clarified so much for me.
EXCELLENT VIDEO, very good presentation, easy to follow and understand; you helped me so much for Nursing Research statistics and data analysis class; I will check out your other videos also. thank you again
Thank you so much.... this helped me study for my advanced statistics midterm
Thanks Brian .. Beautifully explained
