Dr. Elizabeth Vance conducted a cognitive psychology experiment to investigate whether schema-congruent cues enhance the recall of objects from an office scene. In Condition A, participants were shown schema-congruent objects (e.g., a stapler, a desk calendar). In Condition B, participants were shown schema-incongruent objects (e.g., a picnic basket, a toy dinosaur).
Table 1 shows the results of the study.
| Participant | Number of objects recalled in Condition A (Schema-congruent) | Number of objects recalled in Condition B (Schema-incongruent) |
|---|---|---|
| A | 9 | 6 |
| B | 6 | 4 |
| C | 12 | 8 |
| D | 5 | 3 |
| E | 9 | 5 |
| F | 4 | 2 |
| G | 9 | 6 |
| H | 10 | 7 |
| I | 5 | 3 |
| J | 3 | 2 |
| K | 8 | 5 |
| TOTAL | 80 | 51 |
Calculate the measures of central tendency for the data Dr. Vance collected for participant recall in Condition A, and complete Table 2 with your answers.
| Mean number of objects recalled in Condition A (to two decimal places) | Median number of objects recalled in Condition A | Mode number of objects recalled in Condition A |
|---|---|---|
