degrees (f)
text description for graph
which statement is the most appropriate comparison of the
centers?
a. the median temperature for both towns is 40°.

b. the median for town a, 30°, is less than the median for
town b, 40°.

c. the mean for town a, 30°, is less than the mean for town b, 40°.

d. the median for town a, 15°, is greater than the median
for town b, 2°.

Explanation:

Step1: Recall Box Plot Median

In a box plot, the line inside the box represents the median.

Step2: Analyze Town A's Median

For Town A, the box has a line at 30, so median is 30°F.

Step3: Analyze Town B's Median

For Town B, the box has a line at 40, so median is 40°F.

Step4: Evaluate Options

• Option A: Medians are 30 and 40, not both 40. Incorrect.
• Option B: 30 (Town A) < 40 (Town B). Correct.
• Option C: Box plots show median, not mean. Incorrect.
• Option D: 15 and 2 are not medians (they are whisker ends). Incorrect.

Answer:

B. The median for town A, 30°, is less than the median for town B, 40°.
