How do you find the median of a set of numbers?

To find the median of a set of numbers, you first need to arrange the numbers in order from smallest to largest. The median is defined as the middle value of this ordered list. If the list has an odd number of values, the median is simply the middle one. For example, in the set {3, 1, 4}, after arranging it as {1, 3, 4}, the median is 3, which is the middle number.

If the list has an even number of values, the median is the average of the two middle numbers. For instance, in the set {1, 2, 3, 4}, arranged as is, the median would be the average of 2 and 3, giving a median of 2.5. This method effectively captures the central tendency of the data, providing a clear measure of the middle point.

The other choices do not correctly define how to find the median. Adding all the numbers together refers to finding the sum, not the middle value. Choosing the largest number represents finding the maximum of the set rather than the median. Dividing the range by the number of values does not relate to the central tendency but rather applies to measures of dispersion,
