Baseline measure is derived from which condition?

Baseline measure is derived from which condition?

• A. The experimental condition.
• B. Random allocation.
• C. The baseline measure established by the control condition.
• D. The ecological validity.

Answer: (C)

Baseline measure is the starting point used to assess how much change results from the experimental manipulation. It’s derived from the control condition because that group isn’t exposed to the manipulation, providing a standard of normal performance to compare against the effects seen in the experimental group. Random allocation helps ensure groups are comparable, but it doesn’t establish the baseline. Ecological validity is about how well findings generalize to real-world settings, not about baseline measurement. The experimental condition is the one that receives the manipulation, so its outcomes are measured relative to the baseline established by the control condition.
