Question

Find the median.

2, 20, 19, 15, 11, 9, 7, 1


1,2,7,9,11,15,19,20

9+11=20

20/2

Answer 1

10.5 is going to be the answer

Answer 2

The answer is 20/2

To find the median, rearrange the data from the lowest to the highest value. If there is an odd number of data, then the median is the value in the middle. If there is an even number of data, then the median is the mean of the two values that are in the middle.
1, 2, 7, 9, 11, 15, 19, 20

Since the number of data is even, the median is the mean of the two values that are in the middle:
(9 + 11) / 2 = 20/2 = 10
