Median

Median

Middle value in the normal distribution

This line over here this is the median this right over here is the median.

Here are four independent proposals to build molten salt reactors and their dates.

Another way is with the median. And this is to pick out the middle number.

So even though 24 isn't one of these numbers, the median is 24.

So given that, what's the median of this set of numbers going to be? Let's try to figure it out.

The answer is 3 because 3 has 3 data points and no other value has more than 2.

So I'd like you to give me one of those medians here.

So this is the middle of all of the trees that are less than 21, this is the middle age for all of the trees that are greater or older than 21.

let's look at the lecture based classroom, and let's pick the median performance as a threshold.

Let me explain it to you this way the mid ..

The other very typical way is the median. And I will write median. I'm running out of colors.

Just to practice this idea, here's little quiztistics. Here's a sorted list of two digit numbers.

Half of them gave over the Internet.

Next column is standard deviation that is a measure of variability that we'll talk about in detail in a moment.

What is the range of tree ages that he surved?

You can even see it.

So if you were to order all the numbers in your set and find the middle one, then that is your median.

3, 9, 3, 8, 2, 9, 1, 9, 2, and 4.

The mean is always precisely determined.

That's what? 114 2 which is 57.

And hopefully this is reviewed to you, but if not take the time to go through this.

Well, here we have five numbers. We have an odd number of numbers. So it's easier to pick out a middle.

So the median is going to be halfway in between 3 and 4, which is going to be 3.5. So the median in this case is 3.5.

Let's try to order it. So we have 1. Then we have another 1.

So let me give you a list of numbers 5, 9, 100, 9, 97, 6, 9, 98, and 9.

So if you have an even number of numbers, the median or the middle two, the essentially the arithmetic mean of the middle two, or halfway between the middle two.

Kind of a crazy data set. But in this situation, what is our median?

Of course, if there is an even number of elements

So this is the median for all of the trees that are less than the real median, or less than the main median.
