Figure A3 Upper critical values of Student's t Distribution with v Degrees of Freedom

For selected probabilities, a, the table shows the values tv,a such that P(tv > tv,a) = a, where tv is a Student’s t random variable with v degrees of freedom. For example, the probability is .10 that a Student’s t random variable with 10 degrees of freedom exceeds 1.372.
