you could define a global array for your form for the numbers you put in your textbox.
then in your code in your button1.click event you add the values to the array as you add them to listbox1
You then add another button called something like calculate
which will then use the array of your values
to populate listbox 2 and 3 with the corresponding array values in listbox1.

---

if you want them to change as you type you could do the whole thing in your button1.click
just instead of adding your textbox number to listbox1 you add them to a global sorted array
which you will then refer to when populating listbox1,2and 3 simultaneously. hope you
understand my idea

Dim items = (From item In ListBox1.Items
Let parts = item.ToString.Split(New String() {" - ("}, StringSplitOptions.None)
Order By CInt(parts(0)) _
Select item).ToArray
ListBox1.Items.Clear()
ListBox1.Items.AddRange
Dim total As Integer
Dim x As Integer
Dim listboxtotal As Integer = ListBox1.Items.Count
For x = 0 To listboxtotal - 1
total = total + ListBox1.Items.Item(x)
Next
avgnum.Text = Math.Round(total / x, 3)

for y = 1 to listbox1.items.count
ListBox2.Items.Add(ListBox1.Items.Item(y-1)-avgnum.Text)
ListBox3.Items.Add(Math.Pow((ListBox1.Items.Item(y-1)-avgnum.Text),2))
next
