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 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 RU-vid.

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.

Thank you for taking the time to break things down into very basic parts. Like others have mentioned here this video really helped my understanding after having tried to understand using different resources. I think that the reason why so many people are commenting that they understand is because its broken down in a really comprehensive manner. Teaching doesn't have to be convoluted to prove you can figure something out (as some in academia seem to think). Many thanks!

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 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.

Good solid teaching. Could you recommend a tutor just in case. I like that you go slow and explain each step slowly. I am smiling and hope to get an 'A.' I still need a tutor on STAND BY. Smiling.

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.
