T Table – T Distribution Critical Values Table

The T Table stands for the critical values of T Distribution. Even more, T-statistic is helpful when the sample size is smaller and also the variance/standard deviation is unknown. In this article, you will get the knowledge of T Table, T Distribution, and T Values. So, stay with us and read this article carefully.

You can find the table below. Also, you can click on the table image which is given at the bottom of the page and view it a big sized.

What is T Table?

Firstly, the T-Table is different from the Z Table. Many people have this confusion on their minds. So, make it clear. You can use it to find the probabilities for T Distribution. Also, it’s an important data skill.

Firstly, You can see there are many numbers inside the first left column of the table, that defines the Degrees of Freedom (df). Also, there are three headers which you can see below.

  1. Cumulative Probability (cum. prob)
  2. One-tail or One sided alpha
  3. Two-tail or Two sided alpha

Lastly, the table body shows T values.
