There is no meaningful difference between p-values of 0.049 and 0.051, but using default methods, the smaller p-value leads to a conclusion where an …

Did you know?
WebbThe right-tail value is computed by Pr(W ≥ w), which is the p-value for the alternative H 1: p > 0.50. This alternative means that the Y measurements tend to be higher. For a two-sided alternative H 1 the p-value is twice the smaller tail-value. Example of two-sided sign test for matched pairs. Zar gives the following example of the sign test ... WebbThe p value for the hazard ratio of progression free survival is reported as 0.009 in the paper. Even though it's statistical significant, but since the median survival time for patients with control regimen is in fact longer than that with experimental regimen, 12 months versus 8 months.
WebbA one-sided significance test gives a P-value of 0.02. From this we can a) Reject the null hypothesis with 97 % confidence. b) Reject the null hypothesis with 98 % confidence. c) Say that the probability that the null hypothesis is false is 0.02. A one-sided significance test gives a p-value of 0.04. WebbThe P-values based on a one-sided alternative hypothesis will always be ______ the P-value based on a two-sided alternative hypothesis on the same data. the same as larger than …
WebbThe two-sided p-value will be about the same as the one-sided. b. The two-sided p-value will be close to twice as large as the one-sided. c. The two-sided p-value will be exactly twice as large as the one-sided. d. The two-sided p-value will be half as much as the one-sided. c. The two-sided p-value will be exactly twice as large as the one-sided. WebbA one-tailed test, showing the p -value as the size of one tail. In statistical significance testing, a one-tailed test and a two-tailed test are alternative ways of computing the statistical significance of a parameter inferred from a data set, in terms of a test statistic.

Because it’s difficult to see very small p-values in the graph, you can set the option log_yaxis = TRUE so that p-values (i.e. the y-axes) below the value set in cut_logyaxis will be plotted on a logarithmic scale. This will make it much easier to see small p-values but has the disadvantage of creating a “kink” in the p-value … notebook illustrationWebbIn statistics, the multiple comparisons, multiplicity or multiple testing problem occurs when one considers a set of statistical inferences simultaneously or infers a subset of parameters selected based on the observed values..
