Because it is more efficient. It will do it all in one go, rather than a user having to type in two calculations. It will correctly count the cells with values, which a user might make a mistake on. It will automatically take account of any change in the amount of values, like if cells have values removed or cells are inserted or deleted completely. Where possible, users should always try to use functions to do even simple tasks.
The mean of a set of numbers is found by adding them together and dividing by how many numbers were added.
Adding all the scores and dividing by the number of scores yields the mean or average.

An average is found by adding all the relevant numbers together, and then dividing by the number of numbers added. This is a concept learned in elementary school.
In general terms an average is to get a number that is a good representative of a set of numbers. Usually we think of an average as being got by adding all the numbers and dividing by the amount of numbers. Strictly speaking this is the arithmetic mean. A median, which is the middle value, and the mode, which is the most common number, are also forms of average that can be used by statisticians.
the modal/mode in maths is like the average, getting it by adding all pieces of data and dividing on how many there are
The mean is the average of a set of numbers in arithmetic, calculating by adding them together and dividing by the number of them.
