Interpreting Parallel Boxplots
< Prev
Next >

Parallel boxplots are used to display the daily prices of a certain stock over a five-year period from 2017 to 2021. The median price increased steadily from approximately $$58$$ in 2017 to $$78$$ in 2021. The third quartile (Q3) remained at approximately $$84$$. The minimum price did not decrease from one year to the next, and the interquartile range (IQR) either remained stable or decreased over the period. All of the following statements are supported by this information EXCEPT:

A

The boxplots indicate that the interquartile range has noticeably increased from 2017 to 2021, signifying greater variability in daily stock prices over time.

B

The third quartile value appears to remain nearly constant at about $$84$$ throughout the period.

C

The lowest daily stock price has not decreased from one year to the next according to the boxplots.

D

They show that the median daily stock price has steadily risen by roughly 20 points from about $$58$$ to about $$78$$ over the five-year period.
