Clearly expalianed.. Thank you. More interesting interpret the classify in each independent to finding the relationship to dependent. what model for statistical analysis?
Why do you keep saying that you "want" the alternative hypothesis to be true, or that you "want" to reject the null hypothesis? That's not really science, is it?
+jasonroxorz You don't perform a scientific test hoping to show that there's no relationship. If you are using this test in a real life situation, you're saying that you believe there's a relationship there. As a scientist you have to accept that you might have to accept the null hypothesis, but that doesn't mean you give up the desire to show that your hypothesis is supported.
+jasonroxorz In practice, scientists develop theories, write grant proposals, and execute studies hoping that they may discover something interesting about the universe (broadly defined). The null hypothesis is rarely as interesting as an alternative hypothesis, so we usually hope to reject the null hypothesis. For better and for worse, scientific journals tend not to publish studies that fail to reject the null hypothesis. That's science as we currently know it.
I recently got paid quite a bit to do a consumer study in which I failed to reject the null hypothesis... Using that physics degree? haha Anyway, just because scientists are on the tit of corporations and feel the need to release blockbuster results doesn't mean it should be that way. That is not science.
I'm writing an undergraduate thesis and this was very helpful, thank you for taking the time to do this.
You explain things soooo much better than my bored professor mumbles in a 90 minute lecture
Thanks for the explanation.
Was really helpful.
Thank you for sharing! This was helpful.
why he take such a deep breath at 0:08

Very helpful and clear. Thank you.
Hello! i have downloaded this video. thank you very much for that.
Excellent!
Thank you
that "mew" is the greek letter m = μ
60000 people did not finish their chapter :D
You mean independent t test explained exhaustively long...
Lol

In fact you started this video series with, "We always want the data to reaffirm our hypothesis." haha
