Extract data values from the bar chart

\[

$$\begin{aligned} &\text{Sunday: } 6 \\ &\text{Monday: } 4 \\ &\text{Tuesday: } 4 \\ &\text{Wednesday: } 8 \\ &\text{Thursday: } 5 \\ &\text{Friday: } 6 \\ &\text{Saturday: } 9 \end{aligned}$$

\]

Sort the data set in ascending order

\[
\{4, 4, 5, 6, 6, 8, 9\}
\]

Find the middle value of the ordered set

\[

$$\begin{aligned} &n = 7 \\ &\text{Position of median} = \frac{7 + 1}{2} = 4 \\ &\text{Median} = 6 \end{aligned}$$

\]
