Given the numbers 47, 20, 11, 33, 30, 30, 35, and 50, what is the median?

To find the median of a set of numbers, you first need to arrange the numbers in ascending order. In this case, the ordered sequence for the numbers 47, 20, 11, 33, 30, 30, 35, and 50 is: 11, 20, 30, 30, 33, 35, 47, 50.

Once the numbers are sorted, the next step is to identify the median. The median is the middle value in a list of numbers. If the list has an odd number of entries, the median is the middle element. However, in this instance, we have eight numbers, which is an even count.

For an even count, the median is calculated by taking the average of the two middle numbers. In the sorted list, the two middle numbers are the fourth and fifth values (30 and 33). To find the average of these two numbers, we add them together and divide by two:

(30 + 33) / 2 = 63 / 2 = 31.5

Therefore, the median of the given set of numbers is 31.5, making this the correct choice.
