Hi, I'm Jimmy Chang and we're here to talk about how to take an average. Now, an average which is also known as the mean can really be figured out in this simple formula. It's basically the sum of the values, in other words, you wan to add all the numbers that you have together and then you want to divide by the total number of values. In other words, you'd, you want to divide it by how many total numbers that you see. So, for example if you have, let's just say 5, 7, 10, 1 and let's just say 2, in order to find the average of that, what you want to do is you wan to add all of these figures together. So, 5 plus 7 is 12; 10 plus 1 plus, that's going to be 13; so, 12 plus 13 is going to give you 25 and then you want to divide by how many numbers that you have total; 1, 2, 3, 4 and 5; 25 divided by 5 is going to be 5. That is your average. Now, is every average going to be whole? No, not necessarily, it really depends on what kind of numbers that you have and how many figures you have to go with. But, the bottom line is, as long as you add all the values together and divide by how many total numbers there are, you always find your average. So, I'm Jimmy Chang and that's how to take an average.
