Dr Aris is investigating the impact of dual-coding theory on the recall of GCSE History facts.
He recruits two groups of GCSE History students:
After a 15-minute study session, Dr Aris tested all students on a list of 15 historical facts. A score of 10 or above was classified as 'excellent recall'.
Dr Aris's results are shown in Table 1 below.
| Students who achieved excellent recall | Students who did not achieve excellent recall | |
|---|---|---|
| Group X: Dual-coding | 18 | 7 |
| Group Y: Text-only | 8 | 17 |
Draw a bar chart to display the number of students in each group who achieved excellent recall using the data from Table 1.
