14, which is the middle number when they are listed in order.
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
11
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
Mean = 14 Median = 12 Mode = 12
Median of the set = arithmetic mean of 8 and 9 = 8.5
10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
11
It is: 11
