What critical value should be compared to the t value obtained as the test statistic? Solution: The sample size is 12. Hence the degrees of freedom ( df) = 12 - 1 = 11. Mapping the alpha level across the row for one-tailed alpha values and the df of 17 on the left-side of the table, we get our critical value as 1.363. When is T Distribution used?
T Table contains the critical values of the T Distribution. The column contains all the T-Distribution probabilities denoted by "Alpha" or "p". The row contains all the degrees of freedom denoted by "df". Also, here you will get one and two tail T score tables or charts online.
Student t-Value Calculator. In order to calculate the Student T Value for any degrees of freedom and given probability. The calculator will return Student T Values for one tail (right) and two tailed probabilities. Please input degrees of freedom and probability level and then click "CALCULATE"
