11 12 15 16 18 17 the answer is 15.5
11
12
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
15
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
It is 11.5
First put them in numerical order,12, 13, 13, 15, 15, 18.since there is an even set of numbers the median is the mean of the two middle numbers12, 13, 13, 15, 15, 18.(13+15)/2=14
It is 15.
14, which is the middle number when they are listed in order.
11 12 15 16 18 17 the answer is 15.5
15
sorted sample: 8 8 9 11 13 17 18 number of elements: 7 middle element and, therefore, the median: 11
It is 17.
11
Range: 9 Mean: 12.43 Median: 12 Mode: 9
16.5 is the median.
