We have a list of 12 ages, and we want to, first of all, find what the mean is.
00:05
And so the mean, we need to add up all those numbers and divide by 12, which is the number of numbers.
00:13
And i find that the sum of those numbers comes out to be 307.
00:17
And then i'm dividing that by 12.
00:19
So i get a mean age of 25 .58, and it comes out three repeating.
00:25
Now we need to find the median.
00:28
And the median, we have 12 numbers.
00:30
Going to be six numbers here, six numbers here.
00:33
We need our median to be right in between the sixth and the seventh number.
00:38
And i'm not going to list them all down, but make sure you sort them.
00:42
You need to sort that list.
00:44
And when we put them in order, the smallest one is 18, and the sixth number is 22...
