What’s a control group?
- It’s a group included with the experiment but are still partialy separated from the experiment.
- It’s a group included with the experiment.
- It’s a group separated from the rest of the experiment.
- It’s a group separated from the rest of the experiment but are still included in the test.
Explanation:
The correct answer is **the second option**: **It’s a group separated from the rest of the experiment**. A control group is an essential component of scientific experiments, including those conducted in marketing research. It consists of a set of subjects or items that are intentionally not exposed to the experimental treatment or intervention being studied. By isolating the control group from the experimental conditions, researchers can observe and compare how the dependent variables change in response to the experimental manipulation. The control group serves as a baseline or reference point against which the effects of the experimental treatment can be evaluated. Its separation from the rest of the experiment ensures that any observed differences in outcomes can be attributed to the experimental intervention rather than other external factors. This design helps researchers assess the effectiveness and impact of the intervention accurately, providing valuable insights into its effects on consumer behavior, preferences, or attitudes. Therefore, defining a control group as a group separated from the rest of the experiment accurately reflects its role in experimental design and data analysis, facilitating robust and reliable conclusions in marketing research.
