What is the median of the height of buidings in feet:
8 , 12 , 6 , 8, 12 , 18 , 11, 20 , 8
The median is the middle value when a set of numbers is arranged in order from least to greatest.
Arranging the heights from least to greatest:
6, 8, 8, 8, 11, 12, 12, 18, 20
There are nine heights, so the middle value is the fifth one:
6, 8, 8, 8, [11], 12, 12, 18, 20
Therefore, the median height is 11 feet.
To find the median of a set of numbers, we need to arrange the numbers in ascending order first:
6, 8, 8, 8, 11, 12, 12, 18, 20
Next, we determine the middle value. Since there are 9 numbers in the set, the middle value is the 5th number, which is 11.
Therefore, the median of the height of the buildings is 11 feet.
