It's easier for people to help you if you show the error you are seeing.

In this particular case, since you are not initializing sum, the first
time the program encounters:

sum += num

you are effectively doing:

sum = nil + num

Something like this:

> nums = Array.new(8) { rand(10000) }
> max = 0
> min = 10001
sum = 0

Also, in this case it's irrelevant, but you might wish to initialize
min and max like this instead:

min = max = nums[0]
