Example: t-distribution vs z-distributionIf you measure the average test score from a sample of only 20 students, you should use the t-distribution to estimate the confidence interval around the mean.

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).

U+A786 Ꞇ LATIN CAPITAL LETTER INSULAR T and U+A787 ꞇ LATIN SMALL LETTER INSULAR T are provided for use by phonetics specialists. Degrees of freedom is related to your sample size, and shows how many ‘free’ data points are available in your test for making comparisons. See the history of Polish orthography article on Wikipedia for more, and t for development of the glyph itself.

If you are studying one group, use a paired t-test to compare the group mean over time or after an intervention, or use a one-sample t-test to compare the group mean to a standard value. The digraph ⟨ti⟩ often corresponds to the sound /ʃ/ (a voiceless palato-alveolar sibilant) word-medially when followed by a vowel, as in nation, ratio, negotiation, and Croatia. 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. so we can reject the null hypothesis of no difference and say with a high degree of confidence that the true difference in means is not equal to zero.Normally-distributed data form a bell shape when plotted on a graph, with more observations near the mean and fewer observations in the tails.
