What type of methodology creates two groups based on the campaign’s audience targeting, where one group has been exposed to the ads in the campaign and the other has not?

Control vs. Treatment Methodology is the correct answer because it accurately describes the experimental design where a campaign's audience is divided into two groups: a "treatment" group that receives the intervention (exposure to ads) and a "control" group that does not. This allows marketers to isolate the impact of the ads by comparing the outcomes between the two groups. Double Blind Methodology is used in research to prevent bias by ensuring neither the subjects nor the researchers know who is in the control or treatment group, which isn't directly applicable to ad exposure. Blind vs. Exposed Methodology is not a standard scientific or marketing research term. The Scientific Method is a broader process of inquiry, not a specific methodology for group creation in this context.
