Using it's concept, the interval that contains the median number of characters is: 30 - 40.
<h3>What does the histogram shows?</h3>
The problem is incomplete, but researching it on a search engine, we have that:
- She had 3 messages between 0 and 10 characters.
- She had 1 message between 10 and 20 characters.
- She had 1 message between 20 and 30 characters.
- She had 2 messages between 30 and 40 characters.
- She had 1 message between 60 and 70 characters.
- She had 1 message between 100 and 120 characters.
<h3>What is the median of a data-set?</h3>
The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
In this problem, we have a data-set of 9 elements, hence the median is the 5th element, as:
- The first half is composed by the first four elements.
- The second half is composed by the last four elements.
The fifth element of the histogram is in the interval 30-40, which is the interval that contains the median.
