I only know how to check checked, have no idea how to include the ! (not).. I want to check how many checkboxes are left unchecked when a checkbox is checked.. 

$('ul li input:checkbox:checked').each(function() {
      var count = 0;      
      var lenghtOfChecked = count++;
});

Reset to default 7

This way:

var lengthOfUnchecked = $('ul li input:checkbox:not(:checked)').length;

Demo: http://jsfiddle/Vq9A9/

use .not(:checked)

$('ul li input:checkbox').not(':checked').each
