Mean = 14 Median = 12 Mode = 12
16.5 is the median.
In order, the numbers are 18, 21, 24 and 37. Since there are an even number (4) of them, the median is the average of the middle two. ie median = (21+24)/2 = 22.5
Mean = 20 Median = 18 Mode = 18 Range = 9
Between 11 and 21: 12, 14, 15, 16, 18 and 20.
12x21/18+29-11= 32
As there is an even number of them, the median is the mean average of the middle two, namely (18+24)/2 = 21.
The median is the number in the middle. First put the numbers in order:18, 21, 24, 37.Because there are an even number of numbers, there are two numbers in the middle: 21 and 24. The median is the average of these numbers : (21+24)/2 = 22.5.
