Which choice is the median number of tickets sold?
For box-plot questions about center, go straight to the median line inside the box. Do not confuse it with the edges of the box (quartiles) or the whisker ends (minimum and maximum).
Hints
Locate the median marker
Look for the line drawn inside the box (not the whiskers).
Read the value from the number line
Match that line up with the labeled values on the number line.
Desmos Guide
Use the box plot structure
Recall that in a box plot, the median is the line inside the box, while the whisker ends show the minimum and maximum.
Read the median from the scale
Find the line inside the box and read its value using the number line labels; select the answer choice that matches that value.
Step-by-step Explanation
Identify the median on the box plot
In a box plot, the median is the vertical line drawn inside the box.
Read the median value
The line inside the box is at 400 on the number line, so the median number of tickets sold is 400.
