The table shows the number of students participating in four activities over three years.
Which activity saw the highest average participation across years?
Show answer & explanation
Correct answer: D
Explanation
To find the activity with the highest average participation, we can calculate the total participation for each activity across the three years (as the number of years is the same for all):
• Sports: 80 + 85 + 90 = 255 → Average = 255 / 3 = 85
• Music: 75 + 80 + 82 = 237 → Average = 237 / 3 = 79
• Drama: 78 + 81 + 83 = 242 → Average = 242 / 3 ≈ 80.67
• Debate: 82 + 86 + 88 = 256 → Average = 256 / 3 ≈ 85.33
Therefore, Debate had the highest average participation across the years.
