This question gives you a list of numbers and asks you to find the median.
00:04
The list, which is already in order, goes 27, 35, 39, 42, 47, 57, 51, and 54.
00:19
Now, a median is the point in, essentially in the middle of your data.
00:27
The median point is defined as the point where the amount of data that's greater than the median is the same as the amount that's less than the median.
00:38
So when we have a list that's already in order like this, it's pretty easy to find the median.
00:44
We just need to know which one is in the middle.
00:47
One way we can do that is we can just cross off the first and last as we go, and we'll eventually reach one or two and find that 42 is our median.
00:59
But another way to do that and a way that is a lot faster when you have bigger sets is to figure out how many total data you have...
