Marcus's Research on Social Influence

Marcus conducted a study to investigate whether shoppers are more likely to comply with a request to sign a petition depending on what the person asking is wearing. He used two conditions: a researcher dressed in high-vis workwear, and the same researcher dressed in casual clothing (jeans and a t-shirt).

He recorded the number of shoppers who agreed to sign the petition and those who refused in each condition. The results are shown in Table 1.

Table 1: Compliance rates by clothing type

	Person in high-vis workwear	Person in casual clothes
Approved and signed the petition	18	6
Declined to sign the petition	12	24

Explain one improvement that could be made to the experimental design used in Marcus's research.
