So in this question, you've been asked to find the mean, and you know that the mean is x -bar, this is equal to the summation of x -y over n.
00:09
So when we sum everything, you're going to get 15 plus 14 up to get 4, divided by 10.
00:15
And here we get 1 -19 divided by 10.
00:19
So our answer is 11 .9.
00:23
So we are defined for the median.
00:26
And we know for the median, we need to arrange our numbers in ascending order.
00:31
So we get to 4, 8, 9, 12, 14, 15, 17, 19, and 19.
00:47
So here we know n is equal to 10, which means that it's even.
00:53
So our median will be equal to the value.
01:05
So our median will be equal to two values.
01:07
Let's actually check.
01:08
We have 1, 2, 3, 4, 5, 6...
