Hi,

Im trying to calculate the mean/average of numbers in an array any suggestions with the mean() would be very much appreciated.

how can i get the length of an array to perform in a simple / maths problem whilst being flexiable to the length of the array?

function sum()
{
var i=0
for (i=0, total=0;i <numbers.length; i++)
{
total += numbers[i];
}
document.getElementById("txtTotal").value = total;
}



function mean()
{

document.getElementById("answer") = parseFloat(document.getElementById("txtTotal").value) / parseFloat(numbers.length);
}
