totally lost.

I have a project due today and i can figure it out can anyone help.

here are the guidelines

Specifics
You will use 1 file to enter all the scores. The file is named Data.txt and should be stored in the projects Debug folder. The scores are floating point numbers.

One button should calculate the mean, range, and standard deviation and display them.
You must use separate functions to calculate the 3 statistics.

One button should display the frequencies in tabular form. For this exercise, the frequencies we are interested in are as follows:
# scores < 60
60 <= # scores < 70
70 <= # scores < 80
80 <= # scores < 90
90 <= # scores

You must use a separate array to hold the totals for the individual ranges.

All scores should be displayed in a listbox.

here is what i have now which isnt much.

Option Strict On
Public Class Form1

    Private names() As String = IO.File.ReadAllLines("data.txt")
    Private scores(names.Count - 1) As Integer

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        For i As Integer = 0 To names.Count - 1
            scores(i) = CInt(names(i))
        Next
    End Sub
    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Me.Close()
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


    End Sub

    Function mean(ByRef sum As Integer) As Integer
        Dim total As Integer = 0
        For i As Integer = 0 To scores.Count - 1

        Next
        Return sum
    End Function

End Class

For starters, if the amounts are floating point numbers, you should be using doubles and not integers. Also, you're going to need five additional arrays to hold the data for each of the ranges and should populate those in a Select Case or If statement as you're populating the scores array.

Then, create a function for each of the requirements and pass the scores array into them to return and display the value.

So, what is your question ?
And Your guidelines clearly state that the scores are floating point and yet you are using Integers. Why ?

i need help doing this. And yes i put integers because im a idiot. i dont know what is going on i can figure out how to calculate the range, mean, and standard deviation from the "data.txt" file.

The unspoken rule of the forum is that we don't do homework. We might give you typs or point you in the right direction, but that is about it. And considering that there are two other threads about the exact same assignment it shouldn't be to hard to get help

the vb.net form is for helping people and not for paid work, try the http://www.vbforums.com/forumdisplay.php?f=13 form if you want to pay someone to do the work that you don't want to.

Ya, we're willing to help you with any problems you have and point you in the right direction, but we're not actually going to do the work for you.
