First, let's arrange the data set in ascending order:

$$ 1, 3, 5, 7, 9 $$

**Median:**
- The median is the middle number of the ordered data set.
- For the data set $$1, 3, 5, 7, 9$$, the median is **5**.

**Lower Quartile (Q1):**
- The lower quartile is the median of the lower half of the data (excluding the overall median if the number of data points is odd).
- The lower half is $$1, 3$$.
- The median of $$1, 3$$ is $$(1 + 3) / 2 = 2$$.

**Upper Quartile (Q3):**
- The upper quartile is the median of the upper half of the data (excluding the overall median if the number of data points is odd).
- The upper half is $$7, 9$$.
- The median of $$7, 9$$ is $$(7 + 9) / 2 = 8$$.

**Summary:**
- **Lower quartile = 2**
- **Median = 5**
- **Upper quartile = 8**
- **Lower quartile = 2** - **Median = 5** - **Upper quartile = 8**

In the data set below, what are the lower quartile, the median, and the upper quartile? \( \begin{array}{lllll}7 & 9 & 1 & 5 & 3\end{array} \) lower quartile = \( \square \) median \( = \) \( \square \) upper quartile = \( \square \) Submit
