Hmm, I WANT to say that it looks like the median falls right at 28...so that would mean 50 percent would be less than that...but don't want to solidify that statement lol

anonymous · Answer

I know, it's sketchy...

jdoe0001 · Answer

hmm    well.. look at the boxes.. do you think is the green one, or the blue one?

anonymous · Answer

Blue!

jdoe0001 · Answer

right... so we can say that off the options given
is NOT 50%, since the blue box is not taking up half of the whole
is NOT 75%, since it's not even taking half, much less 75%
so the only plausible choices is the obvious one
though the blue box doesn't really look like 1/4 of the whole either, or 25%

jdoe0001 · Answer

the blue box looks more like the 30% of the whole really

anonymous · Answer

@jdoe0001 
It looks like 25% , but are you saying it's  "D" ...?

jdoe0001 · Answer

I'd side with D yes
the box is not small enough to be 25%

jdoe0001 · Answer

looks more like 1/3 or 33%

anonymous · Answer

I thought it would be 25% because it's between 20 and 30 ..

I thought the "green" box would be 33% since it's between 30 and on..

anonymous · Answer

More like 28/29 and on (green box)..

jdoe0001 · Answer

well.. it lies between 20 and 30 because those are the AGES
so yes, the ages of the the "blue" watchers is around 24 - 28
but their percentage of the whole is about 33%

anonymous · Answer

That small blue box is 33% ?

phi · Answer

The box is divided by the mean see http://www.basic-mathematics.com/box-and-whiskers-plot.html in other words, the median is where the blue and green meet. that line is above 28 meaning half of the people are below 28 and half are older

phi · Answer

*The box is divided by the *median*  (not mean)

anonymous · Answer

@phi  Does that mean you can conclude it's "D" ??

phi · Answer

they want you to know that the median occurs at about 28
that means 50% of the people are older than 28 and 50% are younger than 28

anonymous · Answer

@phi Did you check what john doe said...? Because he actually contradicted that it was 50% !

phi · Answer

If you were told that the median age of the viewers was 28, then you would know that half of the viewers are younger than 28.

the box-and-whiskers plot shows you that the median is 28
