Baseline measure is used to compare treated participants to what reference condition?

• A. Untreated participants
• B. Treated participants
• C. Randomized groups
• D. Population norms

Answer: (A)

Baseline measures capture a participant’s starting point before any treatment, providing a reference to judge how much change the intervention produces. In studies of a treatment, the untreated participants serve as the reference condition because they reflect what would happen without the intervention under the same conditions. By comparing outcomes after treatment to those in the untreated group, you can estimate the true treatment effect while accounting for initial differences and natural fluctuations. Population norms are external benchmarks not tied to the study’s reference condition, and randomized groups describe how participants are allocated, not the reference used for comparison.
