[RESOLVED] Find the average value of a listbox

Hi there everyone. I am working on a math program to record students answers to a program. I am looking into getting the average value from a listbox of answers called AnswerList.

Basically, I am wondering how to add up the listbox items because they are all numbers, and then divide by the number of items in the listbox. Would anyone know how I can do that?


Thanks a lot!

This code for example will add up the total sum of the items in the listbox.

VB Code:

Dim I As Integer
 
Dim tot As Integer
For I = 0 To AnswerList.ListCount - 1
tot = tot + Val(AnswerList.List(I))
Next
MsgBox tot

But after that, how would I divide by the number of items?

EdIT: Oh wait, would it just be MsgBox Val(tot / List1.ListCount)?

That seems to work on my end.

Solved, then? Now, maybe you can figure out the mean, the median and even a Bell Curve!!!!

Oh, and make sure you don't dim your average variable as an integer.
