Hello guys!! This is my first topic for learn math. It just a simple formula and easy to understand but we have to understand the meaning first.

The mean (Average) is sum of all the values in set of data then, divide into the total of values in set of data.

Formula of  Mean

The number of Distinction students on a mathematics test for 6 topics were recorded as follows:
