P Value Chart. Defined simply, a P-value is a data-based measure that helps indicate departure from a specified null hypothesis, Ho, in the direction of a specified alternative Ha. Formally, it is the probability of recovering a response as extreme as or more extreme than that actually observed, when Ho is true. (Note that 'more extreme' is defined in the.
It uses binomial distribution to measure the proportion of defectives or non confirming units in a sample. This limitation leads us into the next section to cover a very common misinterpretation of P values. Now that we know our experiment's degrees of freedom and our chi square value, there's just one last thing we need to do before we can find our p value - we need to decide on a significance level.
