Calculate the Arithmetic mean of the following data:

GIVEN:


FORMULA USED:


Arithmetic mean =



∑f = 12 + 20 + 15 + 14 + 16 + 11 + 7 + 8


= 103


∑xf = 180 + 500 + 525 + 630 + 880 + 715 + 525 + 680


= 4635


Arithmetic mean =


Arithmetic mean = = 45


CONCLUSION: Arithmetic Mean of given data is 45
