(2-tailed) – The p-value is the two-tailed probability computed using the t distribution. Webserving a value of U or lower. If the test is one-sided, this is your p-value; if the test is a two-sided test, double this probabililty to obtain the p-value. NOTE: If the number of observations is such that n xn y is large enough (> 20), a normal approximation can be used with µ U = n xn y 2 ,σ U = r n xn y(N +1) 12 , where N = n x +n y.

WebJul 16, 2024 · The p value is a number, calculated from a statistical test, that describes how likely you are to have found a particular set of observations if the null hypothesis were true. P values are used in hypothesis testing to help decide whether to reject the null hypothesis. The smaller the p value, the more likely you are to reject the null hypothesis.
WebIn the output, the P-value, Sig. 2-tailed, is for two-sided test. If you have a one-sided t test, your test P-value should be (Sig. 2-tailed)/2. The one-sample t confidence interval = (Test value + Lower, Test value + Upper). Checking assumptions . One sample t-test assumes that the data follow a normal distribution.
