Enter your answer in the box.

Answer 1

Median is the middle number in a number line up.

The numbers here are: 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130 and 140

Counting from both sides of the lineup, you will find that 110 and 110 are in the middle. Under some circumstances, when there are two numbers in the middle, you add them together and divide by two.

In this case you don’t have too since 110 +110 = 220. 220/2 =110, our original number.

Our final answer, the median is 110.

Median: the medial value of a data set; midpoint.

To find the midian, just go closer one number at a time on either side of the data set until you get to the middle!
