Question

Jade recorded how many characters she used in each of her 999 most recent text messages. Here's a histogram showing her data:

Answer 1

Using it's concept, the interval that contains the median number of characters is: 30 - 40.

What does the histogram shows?

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.

What is the median of a data-set?

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.
