Now that we’ve found Q2, we can use that value to help us find Q1 and Q3. Recall our demo dataset:

`$c(-108, 4, 8, 15, 16, 23, 42)$`

In this example, Q2 is `15`

. To find Q1, we take all of the data points smaller than Q2 and find the median of *those* points. In this case, the points smaller than Q2 are:

`$c(-108, 4, 8)$`

The median of that smaller dataset is `4`

. That’s Q1!

To find Q3, do the same process using the points that are larger than Q2. We have the following points:

`$c(16, 23, 42)$`

The median of *those* points is `23`

. That’s Q3! We now have three points that split the original dataset into groups of four equal sizes.

### Instructions
