Considering the given box-and-whisker plot, it is found that 50% of the data values are between 16 and 72.
<h3>What does a box-and-whisker plot shows?</h3>
A box and whisker plot shows five things:
- The 25th percentile, which is the median of the bottom 50%.
- The median, which splits the entire data-set into two halfs, the bottom 50% and the upper 50%.
- The 75th percentile, which is the median of the upper 50%.
From this plot, we have that:
- The 25th percentile is of 16.
- The 75th percentile is of 72.
Hence, 50% of the data values are between 16 and 72.
