Maybe your script can help? Please. And I understand the theory behind how to work the average, but not how to go about it using a list.Any help?

@Moregamesnow,Thanks for that.But I still can't find out how to practicly go about it.It's not for marks guys, but I want to show that I could do it.And at the moment I'm dissapointed.Practicly I can't.Please help me with coding.From there I'll "decypher" and see what I should have done.

Should I make a basic one?  That just has a list of numbers and outputs the average?

The most important bit of this isn't the code but the understanding. From what I see, you understand the theory and can do it by hand, which is why I'm happy to provide the code. I'm assuming this is a math assignment, or at least that you'll understand whats happening. If you have any questions on it then please ask, its better that you fully understand whats happening.

It seems your main problem is that you haven't included a 'counting' variable, which are very useful when using lists. Thats what the 'counter' variable in the script is for:

1) Make a variable called counter.
2) Add all the values to a list.
3) Make a variable called average

Now first, run this script to find the average.

set [counter v] to (1)
set [average v] to (0)
Repeat (Length of [list v])
set [average v] to ((average) + (item (counter) of [list v]))
change [counter v] by (1)
end
set [average v] to ((average) / (length of [list v]))

This will total up all the values and divide the total by the number of values, thus giving the average.

Now to work out maximum and minimum values:
1) make a variable called minimum
2) make a variable called maximum

set [counter v] to (1)
set [minimum v] to (100000000000000000)
set [maximum v] to (-100000000000000000)
repeat (Length of [list v])
if <(item (counter) of [list v]) < (minimum)>
set [minimum v] to (item (counter) of [list v])
end
if <(item (counter) of [list v]) > (maximum)>
set [maximum v] to (item (counter) of [list v])
end
change [counter v] by (1)

Finally, to find out the values that are greater than the average:
1) make a new list " >average "

set [counter v] to (1)
delete [all v] of [>average v]
repeat (length of [list v])
if <(item (counter) of [list v]) > (average)>
add (item (counter) of [list v]) to [>average v]
end
change [counter v] by (1)
end

I hope this helps, and also that you can understand whats happening here 

So you can run 1 script to work it all out:

when gf clicked
set [counter v] to (1)
set [average v] to (0)
set [minimum v] to (100000000000000000)
set [maximum v] to (-100000000000000000)
Repeat (Length of [list v])
set [average v] to ((average) + (item (counter) of [list v]))
if <(item (counter) of [list v]) < (minimum)>
set [minimum v] to (item (counter) of [list v])
end
if <(item (counter) of [list v]) > (maximum)>
set [maximum v] to (item (counter) of [list v])
end
change [counter v] by (1)
end
set [average v] to ((average) / (length of [list v]))
set [counter v] to (1)
delete [all v] of [>average v]
repeat (length of [list v])
if <(item (counter) of [list v]) > (average)>
add (item (counter) of [list v]) to [>average v]
end
change [counter v] by (1)
end

Thanks for your help prestige! I never had a counter! That's why I couldn't figure it out.

Isn't your min and max values wrong?

I mean, is max=-100000000 and min=1000000 correct?

Ran it,and it worked. My problems, I set my max values in loop to 10000 and min to -10000.And didn't have a counter.

I have another question folks.Been writing a program,and it's challenging me.I wrote a program where the sprite asks you to enter 10 words,and he adds it to the first list.Now,I loop the program,and add the words to the second list.What I want the program to do is reverse the words upon adding to the second list.Example: One,add to second list as enO. Any ideas?

Main reason for program is to get a feel for looping and using the counter.
