P Value from T Score CalculatorThis should be self-explanatory, but just in case it's not: your t-score goes in the T Score box, you stick your degrees of freedom in the DF box (N - 1 for single sample and dependent pairs, (N1 - 1) + (N2 - 1) for independent samples), ...
Use the t-statistic calculator (t-value calculator or t test statistic calculator) to compute the t-value of a given dataset using its sample mean, population mean, standard deviation and sample size. Read further where we answer to the following questions: What is the t-statistic? How do ...
To calculate the p-value from a t-statistic, use at-tableand locate the degrees of freedom in the leftmost column. Then, locate the desired p-value in the heading row, 0.05 is most commonly used for a 95% confidence level. Then, find the intersection of the row and column to find th...
P value formula X is the test statistic value, and you know the distribution of X.For example X may be Z, T etc. Left tailed: P-value = p(x≤X) Right tailed: P-value = 1 - p(x≤X) Two tailed: P-value = 2 * Min( p(x≤X), 1 - p(x≤X) ) ...

This simple confidence interval calculator uses a t statistic and sample mean (M) to generate an interval estimate of a population mean (μ).The formula for estimation is:μ = M± t(sM) where:M = sample mean t = t statistic determined by confidence level sM = standard error = √(s2/...
