The calculator will return Student T Values for one tail (right) and two tailed probabilities. This table contains critical values of the Student's t distribution computed using the cumulative distribution function. The t distribution is symmetric so that. t 1-α,ν = -t α,ν . The t table can be used for both one-sided (lower and upper) and two-sided tests using the appropriate value of α. Student’s t distribution table has the following structure: The row represents the upper tail area, while the column represents the degrees of freedom. The body contains the t values. Note that for on-tail distribution the values are for a and for two-tailed distribution values are for a/2. Let’s say n = 3, the df= 3-1 = 2.

### To learn more about Student's t distribution, go to Stat Trek's tutorial on the t distribution. In the dropdown box, describe the random variable. Enter a value for degrees of freedom. Enter a value for all but one of the remaining text boxes. Click the Calculate button to compute a value for the blank text box.

## When you look at the t-distribution tables, you'll see that you need to know the “df. ” This means “degrees of freedom” and is just the sample size minus one.

The t distribution table values are critical values of the t distribution. The column header are the t distribution probabilities (alpha). The row names are the degrees of freedom (df). Student t table gives the probability that the absolute t value with a given degrees of freedom lies above the tabulated value. Example : with df = 10, for t=2.228, the probability is alpha=0.05 This table contains critical values of the Student's t distribution computed using the cumulative distribution function. The t distribution is symmetric so that. t 1-α,ν = -t α,ν . The t table can be used for both one-sided (lower and upper) and two-sided tests using the appropriate value of α. t-Distribution Table t The shaded area is equal to ﬁ for t = tﬁ. df t:100 t:050 t:025 t:010 t:005 1 3.078 6.314 12.706 31.821 63.657 2 1.886 2.920 4.303 6.965 9.925 3 1.638 2.353 3.182 4.541 5.841 T-Distribution Table (One Tail) For the T-Distribution Table for Two Tails, Click Here. df a = 0.1 0.05 0.025 0.01 0.005 0.001 0.0005 ∞ ta = 1.282 1.645 Search Responsive Menu t Table cum. prob t.50 t.75 t.80 t.85 t.90 t.95 t.975 t.99 t.995 t.999 t.9995 one-tail 0.50 0.25 0.20 0.15 0.10 0.05 0.025 0.01 0.005 0.001 0.0005 two-tails 1.00 0.50 Student t-Value Calculator In order to calculate the Student T Value for any degrees of freedom and given probability.
