Question

Find the median of the following numbers

7.8
10.7
11.2
12.4
14.6
15.3
21.5
30.4

Answer 1

To find the median of a set of numbers, we first need to arrange them in ascending order. The numbers you've provided are already in order:

7.8, 10.7, 11.2, 12.4, 14.6, 15.3, 21.5, 30.4

There are 8 numbers in this set (an even number). To find the median, we take the two middle numbers and calculate their average.

The two middle numbers are the 4th and 5th numbers:

- 4th number: 12.4
- 5th number: 14.6

Now we calculate the median:

\[
\text{Median} = \frac{12.4 + 14.6}{2} = \frac{27.0}{2} = 13.5
\]

Thus, the median of the given numbers is **13.5**.
