Matched pairs is based upon dependent samples.

Question

BlackTom AI · Accepted Answer

The statement concerns the nature of a matched pairs design in statistics.
First, consider what a matched pairs design means: it involves dependent samples where measurements are paired in a meaningful way, such as two measurements on the same subject (before/after), or two subjects that are matched on key characteristics.
This dependence arises because each pair is linked, so the two observations within a pair are not independent of one another. Analyzing such data typically uses methods that account for the pairing, like a paired t-test or conditional analyses.
In contrast, independent samples would consist of two groups where observations in one group have no inherent linkage to observations in the other group, and tests like the independent-samples t-test would be appropriate.
Because the core idea of matched pairs relies on the dependence within each pair, the statement that matched pairs are based upon dependent samples is accurate.
If one were to consider counterpoints, any assertion claiming that matched pairs involve entirely independent samples would be incorrect, since the pairing introduces dependence; similarly, treating paired data as two unrelated groups would ignore the pairing and reduce statistical power.
Overall, understanding the dependent nature of matched pairs clarifies why specialized analytical approaches are used for paired data instead of methods assuming independence.
