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.

Table 1: Number of words recalled in a memory task

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.

You must give your answer to one decimal place.
