Step 1:: Order the data from least to greatest.
The ordered data is: 3, 4, 4, 6, 7, 9.
Step 2:: Determine the number of data points, denoted by $n$.
n = 6
Step 3:: Since $n$ is even, the median is the average of the two middle numbers.
\text{Index of } \frac{n}{2}+1 = \frac{6}{2}+1 = 4
Step 4:: Find the two middle numbers.
\text{Middle number 2} = 6
Step 5:: Calculate the median by taking the average of the two middle numbers.
\text{Median} = \frac{4 + 6}{2} = 5
Final Answer
The median of the given data is 5.
