The median is 8.

Mean: 19 and 1/6 Median: 20 There is no mode.

-8 + 19 = 11

The mode is the number which occurs most - so this is 20 The median is the middle number if you write them all in numerical order..... 5, 13, 13, 15, 18, 20, 20, 20 The answer is 16.5 which is in the middle of 15 and 18 To find the mean you add all the numbers up 5+13+13+15+18+20+20+20=124 then divide by the number of numbers in the range (8). 124/8 = 15.5

The median is 9.

The first 8 prime numbers are: 2 3 5 7 11 13 17 and 19 The median is: (7+11)/2 = 9

There is no direct relationship between the range and the median. So knowing that your median is 20 does not automatically give you the range. The median is just the middle value. That does not tell you what the first and last values are, which is what you need to know to find the range. The median of 19, 20 and 21 is 20, and the range is 2. The median of 4, 20 and 79 is also 20, but the range is 75. The median of 8, 16, 17, 23, 50 and 320 is also 20, but the range is 312. So, as you can see, the Median in no way can tell you what the range will be. You need to know what all of the numbers are, or at least the lowest and highest to know the range.

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.

There are 8 numbers. So you need to find the average of the 4th and 5th numbers when they are placed in order. So, average of 16 and 19 = 17.5

11 13 17 19.

13. It is also the mean.

The median is 8.5. The mode is 8. The range is 14.

Quite simply As long as the 4th and 5th numbers are 19 and 20 there is one more 20. The rest should be random numbers that are below 19 or above 20. e.g. 2,12,18,19,20,20,23,25

1 5 6 8 10 11 12 13 The median (or middle number) is 9.

It is: 19/20 because 7/8 = 0.875 and 19/20 = 0.95

sorted sample: 8 8 9 11 13 17 18 number of elements: 7 middle element and, therefore, the median: 11

sorted: 1 2 7 9 11 15 19 20 number of items: 8 middle items: 9 and 11 average of middle items, or median: (9+11)/2 = 10

The middle two numbers are 8 and 10 so the median is 9.

8/19 + 7/13 = 237/247

Mean = 12 Median = 9 Range = 12
