WebbThis t-value calculator calculates the T value based on the given sample size, hypothesis testing method, ... This means that if df > 30, the t-values for each of the respective right probability values will be equal to this row. Let's go over an example. Let's say that for a given data set, the sample size is 12, ... It really depends on which tool do you use to do the calculation. For example, if you use t-tables to compute t-distribution probabilities, you will find that those typically have accuracy of 4 digits. Now, when you use our calculator (or Excel), you get about 15 digits accuracy. You may think that is great and it is better, and … Visa mer This calculator allows you have both a T distribution calculator for two tailed, as well as for left-tailed and two-tailed.
