You can compare your calculated t value against the values in a critical value chart (e.g., Student’s t table) to determine whether your t value is greater than what would be expected by chance. If so, you can reject the null hypothesis and conclude that the two groups are in fact different. T test function in statistical software Find the critical values for a confidence interval when the data is approximately normally distributed.

The degrees of freedom is 38 (n–1 for each group). Looking this up in a t-table (or calculating it in your favorite stats program) you find a p-value < 0.001. Using a two-tailed t-test, you generate an estimate of the difference between the two classes and a confidence interval around that estimate. From the t-test you find the difference in average score between class 1 and class 2 is 4.61, with a 95% confidence interval of 3.87 to 5.35. The Finnish orthography using the Latin script was based on Swedish, German and Latin. No earlier script is known. See the Wikipedia article on Finnish for more information, and t for development of the glyph itself.You don’t care about the direction of the difference, only whether there is a difference, so you choose to use a two-tailed t test. Cook, Richard; Everson, Michael (2001-09-20). "L2/01-347: Proposal to add six phonetic characters to the UCS" (PDF). If there is one group being compared against a standard value (e.g., comparing the acidity of a liquid to a neutral pH of 7), perform a one-sample t test.

Here are some examples. The letter ⟨t⟩ corresponds to the affricate /t͡ʃ/ in some words as a result of yod-coalescence (for example, in words ending in "-ture", such as future). A t-test should not be used to measure differences among more than two groups, because the error structure for a t-test will underestimate the actual error when many groups are being compared.

If you are studying two groups, use a two-sample t-test. The Silesian orthography is based on the Latin alphabet. No earlier script is known. See the Silesian language article on Wikipedia for more, and t for development of the glyph itself. In a few words of modern French origin, the letter T is silent at the end of a word; these include croquet and debut.

A t test can only be used when comparing the means of two groups (a.k.a. pairwise comparison). If you want to compare more than two groups, or if you want to do multiple pairwise comparisons, use an ANOVA test or a post-hoc test. If the groups come from two different populations (e.g., two different species, or people from two separate cities), perform a two-sample t test (a.k.a. independent t test). This is a between-subjects design. If you want to know whether one population mean is greater than or less than the other, perform a one-tailed t test.

Normally-distributed data form a bell shape when plotted on a graph, with more observations near the mean and fewer observations in the tails.

A t-score is the number of standard deviations from the mean in a t-distribution. You can typically look up a t-score in a t-table, or by using an online t-score calculator. The ordinal number twentieth, derived from this letter of the English alphabet, called tee and written in the Latin script.
