An experiment was conducted to investigate the effect of processing depth on long-term memory retention. Six participants were tested under two conditions: after performing a shallow structural processing task and after performing a deep semantic processing task on a list of 30 words. The raw data, representing the number of words recalled by each participant, is presented in the table below.
| Participant | Number of words recalled after structural processing | Number of words recalled after semantic processing |
|---|---|---|
| U | 8 | 18 |
| V | 11 | 24 |
| W | 9 | 21 |
| X | 13 | 27 |
| Y | 7 | 19 |
| Z | 10 | 22 |
Calculate the mean number of words recalled after structural processing.
