Find the median of the values four, eight, 10, 11, six, seven, five, 12, and three.

First, we need to know what the median of a set of values is. The median is the middle value when numbers are in value order. So first things first, we need to place these values in order. I see the smallest value in the list. And I start there. The smallest number is three. The next smallest number is four. From there, we have five and six, followed by seven and eight. Our last three values would be 10, 11, 12 in that order.

After our numbers are in value order, we’re looking for the one in the middle. There are nine numbers. This means that there are four values on the left of the number seven and four values on the right of the number seven. Seven falls in the middle of these values. And that makes seven the median.
