Question

Find the median of this group of numbers: 25.4, 26.3, 27.5, 55.2, 30.7, 34.9, 36.8

Answer 1

To find the median of a set of numbers, you first need to arrange the numbers in ascending order.

Let's arrange the numbers you provided:

1. 25.4
2. 26.3
3. 27.5
4. 30.7
5. 34.9
6. 36.8
7. 55.2

Now, since there are 7 numbers (an odd count), the median will be the middle number. To find the middle number, we can use the formula:

Median position = (n + 1) / 2, where n is the number of data points.

In this case, n = 7:
Median position = (7 + 1) / 2 = 8 / 2 = 4.

The 4th number in our ordered list is 30.7.

Thus, the median of the group of numbers is **30.7**.
