The table below shows the scores of students in a test: Score: 1, 2, 3, 4, 5 and Frequency: 2, 5, 6, 4, 3. Find the median score.

Total frequency = 2 + 5 + 6 + 4 + 3 = 20. The median is the average of the 10th and 11th values. Cumulative frequencies: score 1 → 2, score 2 → 7, score 3 → 13. Both the 10th and 11th values fall in the score 3 group, so the median is 3.
