One-sided and Two-sided Critical Values for Dixon's Outlier Test for Sample Sizes up to n = 30

Critical values for the significance levels α=0.0100, 0.0500, and 0.1000 and sample sizes from n = 3 to n = 30 for Dixon's outlier test have been calculated using Monte Carlo simulation. For the one-sided and two-sided case critical values are determined, which are accurate to within ±0.00001 to ±0.00007.
