The environment in which we study can play an important role in focus and cognitive performance. An educational psychologist conducted an experiment to investigate whether background music affects concentration. Ten students were randomly assigned to one of two conditions.
The number of puzzles solved correctly within 10 minutes (maximum score of 20) was recorded. The data collected is presented in the table below:
| Participant | Condition A Score (Classical) | Condition B Score (Pop) |
|---|---|---|
| 1 | 12 | 7 |
| 2 | 14 | 9 |
| 3 | 11 | 6 |
| 4 | 15 | 11 |
| 5 | 12 | 8 |
Draw a fully labelled bar chart showing the mean score for each condition. Plot the means to two significant figures.
