 Mean

3, 6 ,9, 13,4 ,6, 12, 14 ,11, 2, 2

Arithmetic mean = sum of elements / total number of elements

sum of elements = 3 + 6 + 9 + 13 + 4 + 6 + 12 + 14 + 11 + 2 + 2

sum of elements = 41 + 41

sum of elements = 82

Total number of elements = 11

There fore Arithmetic mean = mean = 82 / 11

Mean = 7.46 (approximately).
