Hello Inquisit, I have a few questions regarding web research and dropout information :1) In order to achieve equal distribution for 12 conditions I chose sequential subject number generation. When I analyze my data, I have 23 subjects who completed the experiment, and 39 subjects who began and then canceled. The subject numbers range from 34 - 282. I tested the experiment online until about subject number 30 and then deleted the web data. Does this mean that about 250 person visited the launch page, but only 39 of them started the experiment? That would be a return rate of about 9,2 % :-((2) the variable computer.ipaddress.1 is in about 50% 0.0.0.0 in my data , while in the other 50% it is an ordinary ip address like 192.168.178.23. Why is that?3) Is it possible to track the participants referrer in the data with a http-referer? This would allow me to monitor the success of online akquisition strategies...4) I included also a stat counter on the ending page. Unfortunately it shows, that 31 people "completed" the experiment, but in fact only 23 completed. Why is that?Thanks a lot for your help!Erik
