The impact of typography on reading comprehension is of interest to cognitive psychologists. A researcher designed an experiment to test whether font style affects the retention of information. Ten participants were randomly assigned to one of two conditions.
After reading, each participant completed a 25-item comprehension test. Their scores (number of correct answers) are recorded in the table below:
| Participant | Condition X Score (Arial) | Condition Y Score (Script) |
|---|---|---|
| 1 | 18 | 12 |
| 2 | 21 | 15 |
| 3 | 17 | 11 |
| 4 | 22 | 14 |
| 5 | 21 | 11 |
Draw a fully labelled bar chart showing the mean score for each condition. Plot the means to two significant figures.
