Reporting p values. P values of statistical tests are usually reported in the results section of a research paper, along with the key information needed for readers to put the p values in context – for example, correlation coefficient in a linear regression, or the average difference between treatment groups in a t-test.. Example: Reporting the results …Finding z=0.11 on the z Table, we see that p = 0.543860. This is the probability that a score will be lower than our raw score, but the question asked the proportion who would be taller. Final Answer (in words): The probability that a woman in the U.S. would be 64 inches or taller is 0.4562, or 45.62% 45.62 %. Your turn!
