11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
15
The number is 15.
(10+20)/2 = 30/2 = 15
15

the answer is 15
The number 20 is.
It is 20, the number in the middle when they are arranged in order.
To find the number that is in the exact middle of two numbers, add the numbers and divide by 2.25 + 15 = 40. 40 divided by 2 = 20.26.9 is one of infinitely many values between 27 and 15.
17... and 19 !
the middle is 15
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 number halfway between 15 and 25 can be found by taking the average of the two numbers. To calculate this, add 15 and 25 together to get 40, then divide by 2 to get 20. Therefore, the number halfway between 15 and 25 is 20.
16
The number is 15.
