What is the median of the numbers 3, 5, 7, and 9?

To find the median of a set of numbers, it is important to first arrange the numbers in ascending order. In this case, the numbers are already in order: 3, 5, 7, and 9.

The median is the middle value in a list of numbers. If there is an odd number of observations, the median is the middle number. However, if there is an even number of observations, as in this case (four numbers), the median is calculated by taking the average of the two middle numbers.

Here, the two middle numbers are 5 and 7. To find their average, you add these two numbers together (5 + 7 = 12) and then divide by 2, resulting in 12 ÷ 2 = 6.

Therefore, the correct median of the four numbers 3, 5, 7, and 9 is 6, which means the right choice reflects the computed median accurately. Understanding how to find the median helps make sense of data sets, especially for larger and more complex sets of numbers.
