Mean/Average
In mathematics, an average refers to a measure of the "middle" of a data set. The most common method is the arithmetic mean. That is why the “Average” is sometimes also and simply called the “Mean”.
Median
The middle value that separates the higher half from the lower half of the data set.
Mean = (1+1+2+3+4+7+10) / 7 = 4 ==>> Average Value
Median = (1,1,2,3,4,7,10) =3 ===> numerical value separate higher from lower value
Mode = (1,1,2,3,4,7,10) =1 ===> numerical value appears most often
