In the concert ticket pricing studies, what was the age range of the online-recruited participant group?

• A. 18-60
• B. 18-31
• C. 21-40
• D. 25-65

Answer: (A)

The main idea here is how who participated affects what the results apply to. Online-recruited studies usually involve adults who can freely consent and who are comfortable using the internet, so the participant pool often spans from late teens to middle age. The age range 18 to 60 fits that pattern by including younger adults through to those in their early retirement years, while excluding minors and older adults beyond 60 who may have different online activity levels or pricing perspectives. This makes it the best description of the group in this study.

A range of 18-31 would miss many participants in their 30s and 40s; 21-40 would omit younger adults and those older than 40; 25-65 would extend beyond 60, which isn’t indicated for this online-recruited sample.
