A researcher investigated retrieval failure using an independent groups design.
In Condition A, 10 participants learnt 30 words and recalled them in the same room.
In Condition B, another 10 participants learnt the same 30 words in one room and
recalled them in a different room.
The results for Condition B are shown below.
Table 1
Participant | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
Number of words recalled | 9 | 11 | 8 | 28 | 14 | 13 | 9 | 15 | 10 | 12 |
The researcher decided to use the mean to analyse the results.
State one advantage of an independent groups design.
