If anyone is interested in a solution to this which can help to remove any bias from scaled questions, I came up with a small javascript solution which seems to work.
Basically, it generates a random number between 1 and 2 and if it is a 2, the scales are reversed.
In my case, I had a 'Don't know' option at the end which needed to remain fixed.
Here is the code:
Code:
<script type='text/javascript'>
$(document).ready(function() {
var randNum = Math.floor((Math.random() * 2)+1);
if (randNum == 2) {
var place_before="javatbd{SGQ}"+6;
for (var i=5; i>0; i--) {
var move_element="javatbd{SGQ}"+i;
$("#"+move_element).insertBefore("#"+place_before);
}
}
});
</script>
For some reason the code tags don't seem to be working??
