When do you use a 1 tailed or a 2 tail value on the t-distribution table or z-score? Two-tailed hypothesis test: Hypothesis testing in general is a way to test your claims/hypotheses using statistics and known probability distributions. So, when you have some data...

p-value from two-tailed t-test: p-value = 2 × cdft,d(−|tscore|) or, equivalently: p-value = 2 − 2 × cdft,d(|tscore|) However, the cdf of the t-distribution is given by a somewhat complicated formula. To find the p-value by hand, you would need to resort to stati...
