WebMay 26, 2024 · However, both t-values are equally unlikely under H 0. A convention is to compute p for t = -2.2 and the opposite effect: t = 2.2. Adding them results in our 2-tailed p-value: p (2-tailed) = 0.028 in our example. Because the distribution is symmetrical around 0, these 2 p-values are equal. So we may just as well double our 1-tailed p-value. WebThe p value does not allude to the strength or size of an effect, difference, or relationship. Adding a correlation coefficient or the mean value helps the reader in better understanding your findings. Write exact p values for primary outcomes to uphold scientific rigor.
