The median is the number that is in the middle of the set of numbers in order from least to greatest. So in this case we have...1,2,4,4,5,6,7,9 and you cross out one from the left one from the right over and over until you are left with one or two numbers
LOOK AT ATTACHMENT!!!
Now that we have narrowed it down to 4 and 5, we need to add them together (9) then divide it by 2 which would give you the answer of 4.5
So the median of Variable A is 4.5
