The median is 8.
-8 + 19 = 11
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
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.
Mean: 19 and 1/6 Median: 20 There is no mode.

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