First thing you should do is figure out what the median is of the data you were given. Arrange the data from lowest to highest, and find the middle number. If you already did that, just let me know what you got.

26 @jtvatsim

- jtvatsim

Alright, that's what I got too. That rules out choice C for sure.

- jtvatsim

The data ranges from 20 to 32 so we should make sure the box plot actually matches that description.

- jtvatsim

You should see that only one box plot actually does this. :) Can you see it?

- jtvatsim

And by "ranges" I mean...

Those two vertical dashes mark the lowest and highest numbers.

- anonymous

Yes is see it

- jtvatsim

Alright, so which choice do you think it is based on that?

- anonymous

D

- jtvatsim

Careful, that one shows a highest number of 35. Is 35 in our data?

- anonymous

no

- anonymous

It would be C

- jtvatsim

Ah... but then the median is wrong. AHHH!!! lol :)

- jtvatsim

Alright, big breath.... And let's see... we want a median of 26, a low of 20, and a high of 32. We need three things to work.

- anonymous

can you explain why its A so i know

- jtvatsim

So, here's what I would have done. I would draw my own picture like this...

I don't really know anything about the rectangle part, other than that the middle line has to be on 26.

- jtvatsim

So, I would go through and find all the pictures that have a low of 20.

- jtvatsim

OK, they all do. So that didn't help.

- jtvatsim

Next, I would go and find all the pictures that have a middle of 26.

- jtvatsim

It looks like A, B, and D.

- jtvatsim

Finally, I would find all the pictures with a high of 32.

- jtvatsim

Only B has this. The answer must be B.

- jtvatsim

Does that help? Any questions on that process? :)

- anonymous

It does help a lot

- jtvatsim

Awesome!
