Data collected before any intervention is implemented describing the rate of the target behavior prior to intervention are called?

• A. Baseline data
• B. Maintenance data
• C. Progress data
• D. Outcome data

Answer: (A)

The main idea here is identifying what data you collect before any treatment starts. Baseline data are the measurements taken prior to introducing any intervention, establishing a reference point for the target behavior. This initial data helps you see what the behavior looks like before you apply any change strategies, so you can compare later measurements to determine whether the intervention makes a difference.

In contrast, maintenance data are gathered after treatment to see if improvements stick over time without ongoing support, progress data track changes during the intervention, and outcome data summarize results after the intervention has concluded. Because this item asks for data collected before any intervention, baseline data is the correct term.
