  • This statistics video explains how to use the p-value to solve problems associated with hypothesis testing. When the p-value is less than alpha, you should reject the null hypothesis and vice versa. This video discusses when you should use a one tailed test compared to a two tailed test. It contains two example problems that illustrates how to use the p-value method to determine if you should reject or not reject the null hypothesis.

      My statistics teacher doesn't even teach, he just links a CZcams video and calls it a day 😂. Idk why but after COVID, so many teachers have gotten so lazy. I've had multiple teachers that don't even talk during the whole period.

    these videos are really helping me. I've decided to go to university for the first time at 58 years old and I don't think I could do this without your thorough explanations. I hope you have videos on "The one sample t test and interval estimation" and "Testing Hypotheses about the difference between the means of two populations" ..... maybe could you post a link if you cover these topics?

    Thank you so much! You saved me lots of my time grinding on my own! You make stats much easier to understand! I was going to quit my uni course because it simply just so hard to understand. Looking back to my lecture, I found that the key things that u explain in this video they skip most of them. No wonder I reread the lecture so many times and still couldn't get my head around what they want to teach! I felt like my eyes are going to be blind learning from uni lecture. Omg!!! If I have watched this less than 20 mins video before I read the lecture, I would have saved at least half my day and still be able to retend some knowledge.
