WebJun 17, 2016 · More generally, if you place n 2 + 1 values at − 1 n 2 + 2 and one value at n 2 + 1 n 2 + 2 then the mean will be 0 and the standard deviation will be 1 (i.e. these will be internally standardized z-scores), and so we have a way to make the largest z-score in absolute size (by the above construction) to be n 2 + 1 n 2 + 2 > n. Share Cite WebFeb 26, 2024 · If your p-value is near 1, then the observed effect almost exactly equals the null hypothesis value. Far from zero (not close to the null hypothesis value), then your p-value will be low. The data you observe is not likely if the null is true. There are several factors that determine what counts as near and far from the null hypothesis value. WebIf the p-value is greater than the significance level, the decision is to fail to reject the null hypothesis. You do not have enough evidence to conclude that the difference between the population means is statistically significant. You should make sure that your test has enough power to detect a difference that is practically significant. granola for weight gain
