I need help fixing the code (javascript) to have the results in 2 decimal places (except for mode). I also don't know how to create a numeric array. This is for a statistical calculator. Thanks!

performStatistics()

• Input
  • None
• Process
  • Create a numeric array of the values entered in the textarea control
  • Call each of the eight (8) functions (in some order)
    • Calling the functions in the correct logical order will help reduce duplicate code
  • Store the value returned by each function in the value property of the respective control
    • Example: document.getElementById("sum").value=calcSum();
• Output
  • Always return false
    • Otherwise, the web browser may display an error message
