Here we have the number in 10 school districts and we want to know something about it.
00:08
So let's list out the 10 here.
00:10
So 168, 214, 237, 270, 287, 295, 316, 346, 367, and 390.
00:34
Okay, and it says what happens if this 168 goes to 308? okay, how does it affect the mean? how does it affect the median? well, remember that we don't really need to know what the mean is, but remember how we would find the mean is we would add all this up and then we would divide by 10.
01:01
Right, that would give us the mean.
01:04
Well, if 168 goes to 308, we would have to add in another 140.
01:11
So if we add in another 140 on the top and i divide that by 10, that means that the mean would increase by 14.
01:21
Okay, so that is the first answer.
01:24
The mean would increase by 14.
01:27
If i look at the second part of it, it's talking about the median...
