Dr Patel is investigating the effectiveness of a new visual imagery technique for vocabulary learning. She recruits two groups of GCSE French students:
After a 20-minute study session, Dr Patel tested all students on a list of 20 difficult French nouns. A score of 15 or above was classified as 'high recall'.
Dr Patel's results are shown in Table 1 below.
| Students who achieved high recall | Students who did not achieve high recall | |
|---|---|---|
| Group A: Visual imagery technique | 22 | 8 |
| Group B: Normal study methods | 12 | 18 |
Draw a bar chart to display the number of students in each group who achieved high recall using the data from Table 1.
