WebRight-tailed p-value: P (Z > z) = 0.0668072 What is the formula to calculate p-value? It is very difficult to calculate p-value manually. The most commonly employed way of doing this is to utilize a z-score table. In a z-table, the zone under the probability density function is presented for each value of the z-score. WebThe P -value is therefore the area under a tn - 1 = t14 curve to the left of -2.5 and to the right of the 2.5. It can be shown using statistical software that the P -value is 0.0127 + 0.0127, or 0.0254. The graph depicts this visually. Note that the P -value for a two-tailed test is always two times the P -value for either of the one-tailed tests. pickard hair
