Tukey's Honestly Significant Differences (HSD) method is used to compare all possible pairs of means in a dataset. The method takes into account the overall alpha level (typically set at 0.05) and adjusts the individual comparison alpha levels accordingly to control the family-wise error rate. This means that the probability of making at least one Type I error remains fixed, regardless of the number of pairwise comparisons made. Therefore, the correct answer is A) pairwise comparisons.
