A researcher conducted an investigation into visual perception using an ambiguous figure. Participants were shown the image and asked to report what they perceived first. The results are shown in the table below.
Table 1: Frequency of different perceptions of the ambiguous image
| Image perceived | Frequency |

| Young woman | 12 |
| Old woman | 10 |
