Hello there, we've been given a list of numbers.
00:05
The list is as follows, 107, 114, 214, 413, 436, and finally, last but not least, 445.
00:24
And we want to find the mean and the median of this set of numbers.
00:30
So the mean and the median.
00:34
So they're both actually relatively simple calculations.
00:41
For the median, let's just do the mean first actually.
00:44
So the mean is going to see the sum of all these numbers divided by n, which is the total number of numbers that are.
00:55
So what that means is that we're going to add 107 to 114 to 114 to 140, 436, and 445.
01:13
So we're going to add all of these numbers together and we get 1 ,546.
01:19
Now how many numbers did we just add up? we add up 1, 2, 3, 4, 5, 6.
01:24
So we're going to divide 1 ,546 by 6.
01:28
So we get 257 and 2 thirds.
01:39
So 257 and 2 thirds.
01:42
So that is our mean.
01:44
Now our median is a little bit different.
01:46
The way we calculate the median is essentially just by finding the number.
