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.

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.

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!

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.

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.

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.

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.
