[Mathematic Form 3] Mean

The MEAN of a set of data is obtained by adding up all the values of the data and dividing them by the total number of data.

Mean = (Sum of values of data) / (Total number of data)

Eg:

Find the mean of the following sets of data:

a) -8, -5, -3, 0, 0, 1, 2, 8

Solution:

Mean = ( (-8) + (-5) + (-3) + 0 + 0 + 1 + 2 + 8 ) / 8

Mean = - (5/8) or -0.625
