To solve for the first and third quartiles of the given data set, let's first organize the numbers in ascending order and then calculate the quartiles.

### Given Data:
4, 10, 6, 3, 13, 4, 5, 5, 6, 6, 10, 3, 8, 5, 26, 4, 11, 3, 5, 7, 8, 3, 6, 3

#### Step 1: Sort the Data
Sorting these values in ascending order gives:

3, 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 7, 8, 8, 10, 10, 11, 13, 26

#### Step 2: Find the Quartiles
- **First Quartile (Q1)**: This is the median of the lower half of the data. The lower half of the data set is:

3, 3, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5

The median of this half (average of the 6th and 7th values):
\[
Q1 = \frac{4 + 4}{2} = 4
\]

- **Third Quartile (Q3)**: This is the median of the upper half of the data. The upper half of the data set is:

6, 6, 6, 6, 7, 8, 8, 10, 10, 11, 13, 26

The median of this half (average of the 6th and 7th values):
\[
Q3 = \frac{8 + 8}{2} = 8
\]

### Final Answer:
- First Quartile (Q1) = 4
- Third Quartile (Q3) = 8
