00:01
We have a data set, the body temperatures in fahrenheit.
00:05
We want to find the mean and the medium.
00:08
And it recommends using software or a calculator.
00:12
So you can do that.
00:14
You can actually find stuff online, but we'll do it.
00:16
If you don't have software already on your computer, excel will also do it, though.
00:21
So if we find the mean, what we're doing is we're taking every point of data.
00:27
We call those xi.
00:28
We add them all up.
00:30
And we divide by the number of pieces of data.
00:34
So you can get a calculator to do that.
00:38
And when you add all them up and divide by the number of pieces of data, the mean is 97 .95.
00:48
And that's in fahrenheit.
00:52
And then we want the median.
00:54
For the median, what you do is you put all of your data in order from the smallest, all the way up to the largest.
01:03
And then you look for the middle piece of data.
01:08
In this case, we have an even number of pieces of data.
01:11
We have 48.
01:12
So there isn't a very clear medium.
01:14
And when there's not a very clear medium, you look at the 24th and the 25th, and you find the mean of them...
