WebMar 13, 2024 · So what is p value and why is it needed? The p-value roughly indicates the probability of an uncorrelated system to produce datasets that have a correlation at least as extreme as the one computed. That’s probably hard to read. Let me try to make it a bit easier. Let’s take two datasets, one with 10 observations and the other has 1000. WebAnd as we see, the P-value 0.038 is indeed less than 0.05. And so, because of this, we would reject the null hypothesis. We would reject the null hypothesis, which would suggest the alternative, that the true mean is something different than 530 milliliters. And so if we look our choices here, so the first choice says reject the null hypothesis.
