A consumer psychologist investigated how the tempo of background music in an online retail environment affects shoppers' perceived purchase likelihood. Using an independent measures design, one group of participants browses a mock e-commerce store while listening to high-tempo electronic music, while a second group browses the same store with low-tempo ambient music playing.
At the end of the session, each participant rates their likelihood to purchase an item on a scale from 1 to 12 (1 = 'extremely unlikely', 12 = 'extremely likely').
The ratings obtained for each condition are presented in the table below.
| High-Tempo Condition | Low-Tempo Condition | ||
|---|---|---|---|
| Participant | Rating (1–12) | Participant | Rating (1–12) |
| 1 | 4 | 11 | 8 |
| 2 | 5 | 12 | 9 |
| 3 | 3 | 13 | 7 |
| 4 | 6 | 14 | 10 |
