A paired scatter plot connects repeated observations from the same subject, making individual direction and group-level change visible at the same time.
Prepare a directly mappable table
Use repeated or matched measurements in which the same subjects, samples, or units are observed under two or more conditions.
Prepare a long table with one subject-ID column, one condition column, and one numeric measurement column. Each row is one observation.
