Okay, so the arithmetic mean is all of these numbers added together, then divided by the total number of numbers that we're adding together.
00:12
So what that means is we're going to take 4 ,033, 5 ,652, 6 ,407, 7, 201, 8 ,719, 11, 151, 1511, 151, we're going to add all that together, and then we're going to divide by 7.
00:30
Okay, so we're going to go into our calculator to do that.
00:34
So 4033.
00:35
I'm going to just pull up a scientific calculator right here at desmos .com.
00:40
So the first number was 4033, so 4033, plus 5652, 5652, plus 6407 plus 7207 plus 7201, 722 plus 7202.
01:04
Plus 8719, 8719 plus 11154, 11154, and then plus 151, 151, plus 1511.
01:19
Okay, so this is all of our numbers added together.
01:22
I'm going to put parentheses around this, and i'm going to divide it by 7.
01:27
And there we have it.
01:28
That is our average.
01:30
The average, again, is the same as the mean, and that is, where we have all of our numbers added together...
