Fluency Practice

During one re-randomization shuffle, which of the following actually moves, and which stays fixed?

The T/C group labels are reshuffled; each subject keeps its own outcome value.

The outcome values are reshuffled; the group labels stay fixed.

Both the outcome values and the labels are randomly changed.

Nothing moves; we simply recompute the same difference.
