Please enter data above to calculate the average.


The average is the number obtained by adding all the values in the data set, and then dividing by the data set. For example,if a student's test grades are 72, 84, and 99, you can average these by adding together the three grades (72 + 84 + 99 = 255), and then dividing the result by the number of test grades (255 / 3 = 85).

An average is a useful value if you want to weight all the numbers equally. If, however, you had one test that was supposed to be weighted more than the others, or if you wanted to weight the lowest values less, other means might be used to obtain a representation of the data set.
