    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! ❤️

    Most explanations of P-Value on UA-cam 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❤

    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!

    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!

    @Katie-ic4fx 6 років тому +1

    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!

  • @oscarwilde399
    @oscarwilde399 7 років тому +2

    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.

  • @wandag1311

    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.

    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?

    It is true scientists have a personal bias for their alternative hypotheses. But, one of my professors taught me an important lesson when examining results. That is, even if we don't end up having enough evidence to reject the null, we still learn something. "The truth is always more interesting than the hypothesis," he said.

  • @wahjmohamedkhair8018
    @wahjmohamedkhair8018 8 років тому

    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.

  • @tonyhoran7062
