Marcus conducted a field experiment to investigate accent prestige and helpfulness. Two different confederates—one speaking with a strong regional accent and another speaking with Received Pronunciation (RP)—asked passersby on a busy high street for directions. He recorded how many people gave detailed directions or refused/offered minimal help. His findings are summarized in Table 1.
| Regional Accent | Received Pronunciation (RP) | |
|---|---|---|
| Number of passersby who gave detailed directions | 6 | 16 |
| Number of passersby who refused/gave minimal help | 14 | 4 |
Explain one improvement that could be made to the experimental design used in Marcus's research.
