TABLE: Cutoff points for the Student’s t distribution

For selected probabilities, α, the table shows the values tv,α such that P(tv > tv,α ) = α, 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.
