An unconfounded comparison occurs when the two cells being compared differ along only one factor. If they differ along more than one factor, it becomes difficult to attribute any differences observed to a single factor, making the comparison confounded. Unequal sample sizes in the cells or factors do not necessarily impact whether a comparison is confounded or unconfounded.
