To find the first quartile (Q1) of a data set, you first need to arrange the data in ascending order, then use the following steps:

### 1. Arrange the data in order:
\[ 2, 4, 4, 6, 7, 8 \]

### 2. Find the first quartile (Q1):
The first quartile (Q1) is the median of the lower half of the data. Exclude the overall median if the total number of data points is odd.

Since there are 6 data points (an even number), we split the data into two halves:
- Lower half: \[ 2, 4, 4 \]
- Upper half: \[ 6, 7, 8 \]

The median of the lower half is the second number in this list, which is **4**.

### Therefore, the first quartile (Q1) is **4**.

4. How would you calculate the quartiles for a larger dataset?
5. What are the steps to find the quartiles for a set of odd numbers?

**Tip:** Quartiles divide your data into four equal parts, with Q1 marking the first 25% of the data.
