Tukey's Multiple Comparison Method uses the studentized range statistic to obtain the critical value for constructing individual confidence intervals, requires that all sample sizes be equal or at least similar for optimal performance, and is generally considered more conservative and less likely to commit Type I errors compared to the LSD (Least Significant Difference) method, making it more powerful in controlling the family-wise error rate.
