## Do the sets always have to be

## To find the median, we must

To find the median, we must list the values in ascending order so that we can identify the middlemost value.

If we take your solution {4, 4, 5, 4, 23} and rearrange the values in ascending order, we get {4, 4, 4, 5, 23}. So, the median of this set equals 4, not 5 (which is stated in the given information).

## Hi Brent. I have a question.

Thanks

## The set {4,4,5,5,22} has TWO

The set {4,4,5,5,22} has TWO modes: 4 and 5

So, this set would not satisfy the given information.

## Thanks.I get it now.

Let me ask another related question. What happened if we have one set of numbers with two modes?.How works the mode selection there.

Thanks.

## I'm not sure if I fully

I'm not sure if I fully understand your question.

Here are some examples of sets with two modes:

{3, 3, 7, 7, 10, 15}: the modes are 3 and 7

{11, 20}: the modes are 11 and 20

{4, 4, 4, 7, 7, 7}: the modes are 4 and 7

{4, 4, 4, 7, 7, 7, 8, 9, 10}: the modes are 4 and 7
