Final answer:
If one variable is changed to see how it affects behavior, the research study is most likely an experiment.
Step-by-step explanation:
If one variable is changed to see how it affects behavior, the research study is most likely an experiment.
In an experiment, the researcher manipulates the independent variable to observe its impact on the dependent variable. This allows for causal relationships to be established.
For example, if a researcher wants to examine the effect of music on concentration, they may have one group of participants study in a quiet environment (control group) and another group study with background music (experimental group). By comparing the performance of the two groups, the researcher can determine whether music has an impact on concentration.
