| Days | D1 | D2 | D3 | D4 | D5 | D6 |
| Number of students | 2200 | 1800 | 2500 | 2700 | 2900 | 3200 |
Formula used:
Average = Sum of observations/Number of observations.
Calculation:
Average number = (2200 + 1800 + 2500 + 2700 + 2900 + 3200)/6
⇒ 15300/6 = 2550
∴ The average number of students appeared for a exam per day is 2550.
