Tukey's procedure is a more conservative approach to computing confidence intervals for the difference between two means, typically resulting in wider intervals than the t-statistic approach. Therefore, the width of the (1 - α) confidence interval based on Tukey's procedure will be greater than the width of the (1 - α) individual confidence interval based on the t statistic.
