The "adjusted k" in Tukey's HSD is adjusted to take into account the number of unconfounded comparisons we can make out of all the cell means in our interaction. This means that the adjustment factor helps to control the probability of making a Type I error (false positive) when conducting multiple pairwise comparisons among group means. It is important to adjust for the number of unconfounded comparisons in order to avoid inflating the overall alpha level and increasing the risk of making a false discovery.
