Frequently asked questions about Student's t table.

Student’s t table for one- and two-tailed tests.

The critical values of t are difficult to calculate by hand, which is why most people use a t table or computer software instead. Student’s t distribution is the distribution of the test statistic t. The critical values of t are calculated from Student’s t distribution.

Calculating confidence intervals (of means or regression coefficients).

Testing whether two variables are significantly related ( linear regression or correlation).

Testing whether two means are significantly different (two-sample t tests).

Student’s t table is also known as the t table, t-distribution table, t-score table, t-value table, or t-test table.Ī 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.

Student’s t table is a reference table that lists critical values of t.
