28 sie 2020 · The t-distribution, also known as Student’s t-distribution, is a way of describing data that follow a bell curve when plotted on a graph, with the greatest number of observations close to the mean and fewer observations in the tails.
29 kwi 2022 · Student’s t table is also known as the t table, t-distribution table, t-score table, t-value table, or t-test table. A critical value of t defines the threshold for significance for certain statistical tests and the upper and lower bounds of confidence intervals for certain estimates.

In probability theory and statistics, Student's t distribution (or simply the t distribution) is a continuous probability distribution that generalizes the standard normal distribution. Like the latter, it is symmetric around zero and bell-shaped.
The Student's t distribution is a continuous probability distribution that is often encountered in statistics (e.g., in hypothesis tests about the mean). It arises when a normal random variable is divided by a Chi-square or a Gamma random variable.
8 wrz 2024 · Student’s t-distribution, often simply referred to as the t-distribution, is a type of probability distribution that is symmetric and bell-shaped, but it has heavier tails compared to a normal distribution.
This t-distribution table provides the critical t-values for both one-tailed and two-tailed t-tests, and confidence intervals. Learn how to use this t-table with the information, examples, and illustrations below the table.
