### Transcript

Mean is just average. Add up the total and divide by the number of elements.

So in this, case we have 10 elements. They total 540. So just divide

by 10 and their mean is... 54.

OK now let's check out mode.

Mode is just the most frequently recurring element.

We see that in only 1 case does an element repeat itself.

It's the 55 -- right here -- so yep, 55 is the mode and it is the leader in the clubhouse

It's the 55 – right here – so yep, 55 is the mode and it is the leader in the clubhouse

now, one larger than the mean.

OK now the median -- the median is the middle number.

So there's the old Shmoop Camp song that goes with medians -- if ya know it, sing

it with us...

Throw out the high; throw out the low... throw out the high... throw out the low...

And uh yeah -- do that a few times crossing out the highs and lows and what's left in

the middle is ... this.

It's a tie of 55s. Well, normally we'd average these 2 center numbers but in this

case they are the same so... uh... not a lot of work to do here.

We'll call it even at 55. Which ties with mode.

So the answer is both median and mode.

Choice E.

As in, "Element... ary school."
