Calculate the P-Value in Statistics - Formula to Find the P-Value in Hypothesis Testing

In this lesson, we will discuss the very important topic of p-values in statistics. The p-value is a calculation that we make during hypothesis testing to determine if we reject the null hypothesis or fail to reject it.

The p-value is calculated by first finding the z test statistic. Once this is known we then need to find the probability of our population having a value more extreme than the test statistic. This is done by looking up the probability in a normal distribution table. We then interpret the results by comparing the p-value to the level of significance..

I haven't understood a single word that my statistics teacher has said to us this entire semester. Yet I understand this perfectly, on the first time. Not all heroes wear capes. Thank you good sir.

You're the savior of thousands of students across the globe. I thank you, sir, for such good content and lecture.

I have actually watched 4 of his videos in a stretch and still not getting bored. The Professor is a genius. He has done so much to demystify what some lecturers teach and most importantly what most students believe statistics is all about. I really appreciate the importance and relevance of ICT.

I rarely comment on videos... but absolutely love his style..in 20 minutes..the concept is deeply deeply ingrained in my mind. He is passionate and he cares about the topic and his students. God bless you and the world have more teachers like you....we would all be much better students then. Sincere thanks again.

I'm working on my master's of statistics and I've got to say this video was incredibly helpful. Some of the jargon and theory used in my classes are a bit too abstract - I really appreciate the concrete examples!

[balukuroben]

most of the statistics lecturers in universities are so proud that they dont deliver concepts well. I love your approach which makes it easy for students to understand better. Thanks and God bless you

Thanks for saving a confused engineering student during the quarantine.

Taking public health and it includes statistics. Didn't realise that it did, I would have taken something else as I am terrified of maths. My statistics lecturer basically reads the slides to us and expects us to do the rest of the work, I find your videos to be quite explanatory. The alien language I was seeing earlier on in Stats lecture suddenly makes sense and I am proud to say I can now speak alien language too.

I am doing statistical analysis in grad school and needed a refresher. You are such an incredible instructor and I am so grateful for you! This allowed a visual representation of the P-value in a way that really allowed me to understand WHY 0.05 is used. Thank you so much!

[sayakbhattacharjee]

Finally, I can differentiate between z, p value, level of significance. Your lecture proved that most of the lecturers themselves are not confident about the core concept and that's why they can't explain. Thank you very much

[nedaari]

Sir...I have an MAT and MBA from an elite schools. You are talented. The analogies, reasoning and explanations are all on point. Thank you.

[TheShaunico]

You are so awesome! I've been struggling in my class all year because my professor only reads what is on his power points which are very similar to the information in the book. You have broken it down and made out so easy for me to understand. I was thinking that I was just terrible at at statistics. Thank you for giving me my confidence back. I wish I would have found your videos sooner. I wish you would have been my professor. Thank you so much for taking the time to make these videos and putting them on YouTube.

[ramiozil]

We need professors like you in Canada, I really appreciate every minute you’ve spent doing those videos.
Idk how to thank you

[ziyezhu]

his lectures are straightforward and easy to understand, even you get distracted sometimes, you won’t get lost.

[philipcho]

Its really depressing when you're watching stat videos like this at midnight because you don't get what a word your teacher is saying.

I have 2 weeks left of my 8 week applied statistics course and I just absorbed more info (and by absorbed I mean I actually GET IT instead of memorizing it!) in 22 minutes than I have for the past month and a half. I'm disappointed that I didn't find this channel sooner (and I looked!).. so far I have an A in the class, but it's been by the skin of my teeth and incredibly frustrating because it's online. I ask my professor questions, and his answers just confuse me more. I really want to finish strong and I think these videos are going to help me. I will be binging them all!
You have a genuine gift for teaching, I can't thank you enough for sharing your knowledge with the rest of us.

[halimatukamara]

I have been taught Hypothesis testing during my masters course it was difficult for me to comprehend but just listening to all your videos has made it so easier for me to abreast and digest. Well done for the great lectures

My God, you are the best greatest teacher on earth, I don't know if there is or not anyone else that I know that teaches so clearly in detail, you should be an example to the entire world's education systems. The entire world education systems must be changed, this is how everything should be taught, instead of long boring lectures, or reading books that are so hard just to understand what they are trying to tell you, because the way books are written is very official language which I abhor, a simple concept that can take one minute to understand takes hours, because the way these evil books are written, the concepts of science, math and everything else are not hard to learn and are actually fun to learn, if it wasn't for these official languages that are used in all books, I am so sick and tired of them.
This is how everything should be taught in all schools. Simple, fun and clear. They should learn from you, you are the best and made a big difference in my life, truly American teachers are the best too at teaching. But offcourse your ways of teaching makes it the 👌 best.

I’ve never been good at Maths - always my weakest subject at school. Now doing a Masters and a module on stats/quantitative research. This is much clearer than the textbooks and even the lecturer videos! Thanks so much for all that you do ❤️

[Joe_Fauci]

I never thought I could understand math this well, but your videos make it so easy to follow along and learn!
