Here's your shmoop du jour:

00:05

If one more data value of 55 is added to the

00:07

below data set, which values will change?

00:12

And here are the potential answers...

00:16

OK so what is this question asking?

00:18

Well, if we solved the previous problem, we know that the mean

00:22

of the original data set is 54...

00:25

...and the median and mode are both 55.

00:28

Okay, so the new 55 is going to stir the pot a bit.

00:31

But before we spend a ton of time doing a bunch more math, let's look at this logically.

00:35

Our median, the middle number... won't change.

00:38

55 was our median before, and since we're adding another one... it'll still be 55.

00:43

Same thing with mode. We already had more 55's than any other number... so adding

00:48

one more to the mix certainly won't change things.

00:51

Our mean was 54 in the last problem... by adding a 55, our mean is destined to go up

00:56

slightly...

00:58

So our answer is A.

00:59

As in, "All wet."
