Answer:
10.
Explanation:
median means the "middle" number in a set of numbers.
(I always the meaning of median by remembering "middle" because they rhyme).
NOTE: to find the median of a set of numbers you have to arrange that set of numbers in either ascending order (smallest to biggest value) or descending order (biggest to smallest value) .
sooo....
we were given :
11, 17, 7, 4, 15, 19
let's arrange in ascending order
4, 7, 11, 15, 17 , 19
now you can cancel them out ( cancel left number, right number)
i mean....
cancel out 4, cancel out 19
cancel out 7, cancel out 17
and we are left with 2 numbers which are11 and 15.
NOTE; (when you have two numbers or values remaining instead of one number, add those two numbers and divide by 2).
soooo...
11 + 15 = 20
20/2 = 10
median of the set of numbers is equal to 10.
Hope this helps.
Good luck ✅.
