I like the video example a lot. To be accurate, 3T Probability is 0.5*0.5*0.5=0.125; 4T probability is (0.5)^4=0.0625; 5T Probability is (0.5)^5=0.03125; ...

You made my understanding of p value better. Thanks for sharing. As a foot note, suppose my null hypothesis is that Jack Black watched too many of your videos and actually, Jack Black has become popular by imitating you. Opposing that, is my alternative hypothesis, Jack Black is cool, and imitating Jack Black is also cool, but not as cool as Jack, because ... Jack Black. Can we devise an experiment/measurement parameter that will give us that low P value I expect. IE Jack Black is genuine. I propose a Jack Black contest, where viewers create Youtube videos showing of their Jack Blackness, and by voting we try to solve which hypothesis is most likely. Hey just my 2 cents.

Hi MrNystrom, I understand the who concept of rejecting null if the p-value is too low (because it is highly unlikely to get results like the one you got given the null is true and the fact that you DID means the null is false). What I don't get is, why do you calculate the p-value for getting results "at least as extreme as the ones you got" meaning why do you take the area under the curve from the critical value to infinity. Wouldn't it make sense to just find the probability of getting results like the ones you got and not "atleast" like the ones you got?

Wrong. Prob (10 tails in 10 flips of a fair coin) is EXACTLY THE SAME as the Prob (5 tails and 5 heads in 10 flips of a fair coin).

Usually P-value lies between 0 and 1 but for one of my test I'm getting P-value exactly 0.00. Is it valid first of all? also, what does it signify P-val = 0 ?

Hoan Tran (8 месяцев назад)
can I just rephrase what u are saying in term of "t" is that if the null hypothesis was true... then the value t will fall into (assuming p-value 0.01) P (-t1 < t < t1) = 99% instead of 95% (alpha = 5%) so we can reject the null hypothesis. is this correct ?.

I forget my undergrad statistics, but can anyone remind me on formulating Hypotheses in this sense? So I come up with a null hypothesis (that's usually status quo as I understand?).. and then the HA is sort of the inverse of the null. My question is: does the testing have to be binary in nature? Like in this case, the coin can either only be fair or NOT fair. Is there such a thing as testing for multiple scenarios? Like perhaps there would be Null H, HA1, HA2, etc? Thanks in advance
