What is the median of the numbers 1, 3, 3, 6, 7, 8, and 9?

To find the median of a set of numbers, you first need to arrange the numbers in ascending order, which in this case is already done: 1, 3, 3, 6, 7, 8, 9.

The median is the middle number in a sorted list. If there is an odd number of values in the list, the median is the number that is exactly in the middle. Here, there are seven numbers in the list. To find the median, you locate the center position, which can be determined using the formula (n + 1) / 2, where n is the number of elements.

For this set:

• The number of elements (n) = 7

• The middle position = (7 + 1) / 2 = 4

The fourth number in the ordered list is 6, which is the median. The list contains 3 numbers before it (1, 3, 3) and 3 numbers after it (7, 8, 9), confirming that 6 is indeed in the center of the dataset. Therefore, the median of the numbers 1, 3, 3, 6, 7,
