Question

I am making an application that will give me the Mean, Medium and Range of the numbers that have been inserted by the user.
But I cannot seem to add the numbers and then divide them by two.
Here’s what I attempted:

    public static String Find_Mean()
    {
        int Number = 0;
        for (int size = 0; size < list.Count; size++)
        {
            Number = Convert.ToInt16(list[size].ToString());
            Number += Number;
        }
        int Final_Number = Number / 2;
        return Convert.ToString(Final_Number);
    }

What I want to do is add all the numbers together from the arraylist then divide them by 2.

Answer 1

you are re-assigning the value for Number here:

for (int size = 0; size < list.Count; size++)
{
    Number = Convert.ToInt16(list[size].ToString());
    Number += Number;
}     

try this:

for (int size = 0; size < list.Count; size++)
{
    Number += Convert.ToInt16(list[size].ToString());
}
