Which term refers to data collected during the period before introducing the independent variable?

• A. Baseline Logic
• B. Behavior
• C. Behavior Checklist
• D. Baseline

Answer: (D)

Data collected before introducing the independent variable are baseline data. This pre-intervention information establishes a reference point so you can see what the behavior looks like under existing conditions and compare it to what happens after the intervention is applied. Baseline data reveal the level, trend, and variability of the behavior without manipulation, helping you determine whether observed changes after the manipulation are due to the intervention rather than natural fluctuations. The other terms refer to the behavior itself, a recording tool, or the reasoning framework, not the pre-intervention data phase.
