is a continuous probability distribution that generalizes the standard normal distribution. Like the latter, it is symmetric around zero and bell-shaped. Fat-tailed distribution · William Sealy Gosset · Degrees of freedom (statistics) |

Распределе́ние Стью́дента в теории вероятностей — это однопараметрическое семейство абсолютно непрерывных распределений. Уильям Сили Госсет первым опубликовал работы, посвящённые этому распределению, под псевдонимом «Стьюдент». Википедия

28 авг. 2020 г. · The t-distribution is a type of normal distribution that is used with small sample sizes, where the variance of a sample is unknown. |
We have determined that the probability that a T random variable with 8 degrees of freedom is greater than the value 1.860 is 0.05. |
T distribution is used to make assumptions for a mean when the population standard deviation is not known to us and the sample size is small. |
A normal distribution describes a full population, t-distributions describe samples drawn from a full population; accordingly, the t-distribution for each ... |
The t-distribution calculator computes probability, based on t statistics. Fast, easy, accurate. An online statistical table. Sample problems and solutions. |
