the mean (average) can be found by adding up all the numbers, then dividing by how many numbers there are. (5 + 12 + 5 + 1 + 7) / 5 = 30/5 = 6 <== the mean the mode is the number that appears most often...there can be 0 or more modes....but in this case, there is only 1...and that is 5 because it appears more then any other number.
