I have some code that I'd like to adjust to create a statistics calculator, the javascript should calculate the sum, average, max and min value when I entered a list of numbers on a web page; I'd like to use loops.  The results should be added to a list in the web page.

var i, n
var valueCount = 0;
var valueSum = 0;
var valueAverage = 0;
var valueMax = 0;
var valueMin = 0;

$( "#calculate" ).click(processValues);

function processValues() {
  $("#results" ).html( "" );//clears any list items from last calculation
  var valueString = $( "#valueList" ).val();
  var value = $.map(valueString.split(","), Number ); //this is an array
  valueCount = value.length; //get the lenght of the array (number of values)

 function sum() {
   valueString= document.GetElementById("#valueList").value.split(",");
   for(i=0; i <valueString.length; i++) {
     sumofvalueString += parseInt(valueString (i));
  document.GetElementById("valueSum").innerHTML = sumofvalueString;
  $("#results" ).append( "<li>The values entered: " + valueString + ".</li>" );
  $("#results" ).append( "<li>There are " + valueCount + " values.</li>" );
  $("#results" ).append( "<li>The Sum is " + valueSum + ".</li>" );
  $("#results" ).append( "<li>The Max is" + valueMax + ".</li>" );
  $("#results" ).append( "<li>The Min is" + valueMin + ".</li>" );


here is the code for the webpage

<h4>Enter numbers separated by commas and click calculate </h4>
        <input id="valueList" type="text" ><button type="button" id="calculate">Calculate Stats</button>
