So we have five numbers given to us.
00:01
We have 13, 15, 8, 16, and 8.
00:06
And we want to find in part a, the mean, which is a sample mean.
00:10
And so when i find that value, i need to find what the sum of those values is.
00:16
And i find that the sum of those numbers is 700, i'm sorry, is 60.
00:22
And then we want to divide that by five.
00:24
So we see that our mean is 12.
00:27
Now we want to determine our median.
00:28
And we have to be careful on the median.
00:30
A lot of times students will forget to do this simple thing of putting the numbers in order...
