In statistics, the p-value is the probability of obtaining results at least as extreme as the observed results of a statistical hypothesis test, assuming that the null hypothesis is correct

Guys at 3:34 just a small update The p-value is not interpreted as a probability that the null hypothesis is true. It is the probability of observing a value of the test statistic that is as or more extreme than what was observed in the sample, assuming the null hypothesis is true. Dont Forget to subscribe my vlogging channel to see more motivational videos. Happy Learning!! kzfaq.info/get/bejne/fp90lZpyqczHiH0.html

can you please explain what is then the difference b/w level of significance(alpha) & p-value

@rajdama205 Жыл бұрын

Also one more update, p-value isn't significance value. We calculate significance value based on observations and then compare it with p-value to decide if Null Hypothesis is accepted or rejected.

you need to delete this entire video rather than just correcting yourself in the comment section. A student who is new in this domain can easily get misguided.

Understanding p-value took so much time since other posts and videos don't involve animation of distributions in their explanations. I will say this is the greatest explanation one can ask for. Thank you so much, Krish!

@dhruv3344 Ай бұрын

Definition: The p-value is the probability of obtaining a test statistic at least as extreme as the one observed, given that the null hypothesis is true. Interpretation: It quantifies the strength of the evidence against the null hypothesis. A smaller p-value indicates stronger evidence against the null hypothesis.

Finally a video that explained what is happening. I managed to work out a definition from summarising your video.... thank you. 95% of all results will be average. However, 5% or less would be classified as extraordinary. Therefore, if your experiment gave results which are 5% or less than likely to occur on average, the independent variable you have manipulated is significant, because it changed the results from average to extraordinary.

Incorrect definition of p value. It is not the probability of null to be true. It is the probability of finding an extreme point if null is true.

@mehmetkahyaoglu2377 2 жыл бұрын

if p > 0.05 is, then we can say that, we failed to reject that our coin is fair. Else if p < 0.05 is, hypothesis is rejected that our coin is fair. then point is that I want to make a correction. If p is equal to exact 0.05 value, means that we can not say whether it is fair or not.
