TitleStata 6: Obtaining one-tailed probabilities for the t distribution AuthorJames Hardin, StataCorp Thetprobandinvtfunctions both return values based on a two-tailed approach. If you want the output oftprobbased on one tail (the usual cumulative distribution approach) then it depends on whether...
Two-tailed hypothesis tests are also known as nondirectional and two-sided tests because you can test for effects in both directions. When you perform a two-tailed test, you split the significance level percentage between both tails of the distribution. In the example below, I use an alpha o...
A one-tailed test is a statistical test in which the critical area of a distribution is one-sided so that it is either greater than or less than a certain value, but not both. If the sample being tested falls into the one-sided critical area, the alternative hypothesis will be accepted ...
This resulted in a sample consisting of 67 incels and a comparison group of 103 non-incel males, which exceeded the minimum number of participants (34 and 96, respectively) needed to detect a moderate effect size (d = 0.50) with 0.80 power based on an a priori one-tailed power ...
(p = 0.1819 by two-tailed Student’st-test). This result is consistent with the above finding of low cytotoxicity of Os NPs upon light irradiation, which can be explained by the limited phototoxicity of Os(bptpy)22+. Systemically administered free Cb (group 2) did not exhibit ...
Next, a two-tailed Fisher’s test that compares the sequencing read counts collecting variants and the reference alleles in the tumor were performed with each collected variant in a gene. The P-values from all collected variants in a gene were then pooled by Fisher’s method for combing P-...

analysis will be included in the multivariate model. Goodness-of-fit will be evaluated through the Hosmer–Lemeshow test. Statistical analysis will be performed by using SPSS 22.0. A two-tailed significance level of 0.05 will be used for all tests.P < 0.05 will indicate statistical ...
Based on the 10,000 random networks generated, a Z distribution was used to obtain Z-scores and two-tailed p-values for the original pY1H network. This analysis was performed considering: (1) ChIP-seq peaks found in the same cell line, and (2) ChIP-seq peaks found in different cell ...
