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
11
The median is the central value, 10.
It is: 10
14
The mean will increase from 14 to 20. The median will increase from 12 to 15.
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
10 numbers in the sample. Middle numbers are 10 and 14. Then the median is (10+14)/2=12
11
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
The median of 1 and 5 and 5 and 8 and 10 and 12 and 13 and 14 is I think it is 8 and a half.
The median is the central value, 10.
It is: 10
Mean = 14 Median = 12 Mode = 12
6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16
