Math Problem Statement
Solution
To create a box plot based on the data in the image, we need to understand the components and place them correctly on the provided axis:
Given Data:
- Lower Quartile (Q1): 27
- Median (Q2): 35
- Interquartile Range (IQR): 22
- Longest Time (Maximum): 57
- Range: 41 (This suggests the minimum value is
57 - 41 = 16
)
Steps to Create the Box Plot:
-
Identify the Quartiles and Whiskers:
- Minimum (Lower Whisker): 16
- Q1 (Lower Quartile): 27
- Q2 (Median): 35
- Q3 (Upper Quartile): This can be calculated as
- Maximum (Upper Whisker): 57
-
Construct the Box Plot:
- The box should extend from Q1 (27) to Q3 (49).
- The median line should be drawn at 35.
- The whiskers should extend from the minimum value (16) to the maximum value (57).
-
Plotting on the Provided Axis:
- Mark 16 as the starting point for the lower whisker.
- Mark 27 as the beginning of the box (Q1).
- Draw a line at 35 for the median (Q2).
- Mark 49 as the end of the box (Q3).
- Mark 57 as the end point for the upper whisker.
Final Box Plot Representation:
To construct the box plot, you would need to sketch:
- A box from 27 to 49 with a vertical line at 35.
- Whiskers from 16 to 27 and from 49 to 57.

Would you like further details or help with related questions? Here are some possible extensions:
- What are the steps to calculate the interquartile range given Q1 and Q3?
- How can you determine if a value is an outlier in a box plot?
- Why is the median important in a box plot?
- How would the box plot change if the maximum waiting time was 65 minutes instead of 57?
- What information can we infer about data spread using the range and interquartile range?
Tip: Remember that the box in a box plot represents the interquartile range (middle 50% of the data), which helps identify how data is distributed around the median.
