Question

The enrolment of a school during six consecutive years was as follows:
1620, 2060, 2540, 3250, 3500, 3710.
Find the mean enrolment.
​

Answer 1

Given data,

1620, 2060, 2540, 3250, 3500, 3710

Here, n = 6

∴ Mean (x)

Ʃ xi/ n = (1620 + 2060 + 2540 + 3250 + 3500 + 3710)/5

= 16680/6 = 2780

Therefore, the mean enrollment is 2780.
