How do you work out the mean of a set of numbers?

You find the mean of a set of data by adding up all of the values then dividing the number you get by the total numbers in the data. An example of this is: 'Find the mean of '6, 8, 9, 17' -First you add up all the numbers 6+8+9+17= 40 -Next count how many numbers there are in totalIn our example there are 4 numbers -Finally divide the total number found from adding by how many numbers40/4 = 10This means that the mean of the data is 10!
