Mahesh Godavarti

The simplest way is to add all the numbers up and divide it by the count (i.e. how many numbers were used to calculate the total).

If the numbers enjoy some specific properties, then you can come up with other ways to find the mean. However, for now, it's best to just stick with:

  1. Count the number of data points
  2. Add the data points to get a Total
  3. Divide Total by Count to get the mean
David Buenrostro

The best way to find the mean is to add up all the numbers in the data set. Then you divide that number by the # of numbers in the data set.
