Figure 3: A Bland-Altman plot illustrating the agreement between the Fresno test and the Berlin Questionnaire* *The Bland-Altman plot provides a visual assessment of the agreement between the readings of two different scales that measure the same property by plotting the average against the difference between the readings of the two scales. We used the Bland-Altman plot to depict the agreement between the student scores in the Fresno test and the Berlin Questionnaire, both of which were developed to measure competence in Evidence Based Medicine. In the fi gure above, each data point was constructed by plotting each student's average scores of the Fresno test and the Berlin Questionnaire (X-axis) against the difference in scores between the two instruments (Y-axis). The mean difference in the participants' scores between the two instruments and two standard deviations on either side of the mean are also displayed
