Question

question 3 1 pts which of the following is used to provide a baseline for comparison to let you know that the treatment was effective?
repeated trials

a dependent experiment

a variable experiment

a controlled experiment

Explanation:

To determine which option provides a baseline for comparison to show treatment effectiveness, we analyze each:

• Repeated trials: Involve doing an experiment multiple times for reliability, not for a baseline.
• A dependent experiment: Depends on another, not for baseline comparison.
• A variable experiment: Focuses on variables, not a baseline.
• A controlled experiment: Has a control group (baseline) and experimental group, allowing comparison to see if treatment worked.

Answer:

D. a controlled experiment
