Group: Forum Members Posts: 13, Visits: 5	thanks again! I think it might be the necessity to download a ".exe" for the experiment that potentially scares many wary participants. Do you have any reommendations for designing the starting page in order to emphasize the trusthfulness of the download/ experiment? Regards, Erik

Group: Administrators Posts: 13K, Visits: 109K	I hosted the experiment on http://research.millisecond.com/aowbonn/handball.web and advertised in forums and facebook groups/walls that contain my population of interest. I started advertising on tuesday. Might be that a bunch of people clicked the link to your launch page, gave it a quick look and then dismissed participation for whatever reason (see below). Perhaps there's a better way to acquire participants / increase return ratio than Facebook? But is it right, that when a person visits the launch page and does not start the experiment, the subject count is increased by one? Yes, as subject numbers are generated on the server side. You can test this for yourself by visiting your launch page, locating the subject number in its source code, reloading the launch page and locating the (new) subject number. Are search robots crawling http://research.millisecond.com/aowbonn/handball.web ? It would seem so. Just google "site:research.millisecond.com" (no quotes). However, I'm not entirely sure if this will do anything to the subject count. As I informed my participants that they can cancel the experiment with strg + q, I think this increased also my stat counter. Yes. Aborting the experiment via CTRL+Q will invoke the finish page, thus increasing the stat counter. Regards, ~Dave

I hosted the experiment on http://research.millisecond.com/aowbonn/handball.web and advertised in forums and facebook groups/walls that contain my population of interest. I started advertising on tuesday. But is it right, that when a person visits the launch page and does not start the experiment, the subject count is increased by one? Are search robots crawling http://research.millisecond.com/aowbonn/handball.web ? Sorry for being unprecise, I specified a custom finish page with a counter using the webscript registration wizard. As I informed my participants that they can cancel the experiment with strg + q, I think this increased also my stat counter... Regards, Erik

Group: Administrators Posts: 13K, Visits: 109K	Does this mean that about 250 person visited the launch page, but only 39 of them started the experiment? Not necessarily. It might be that search robots crawling your launch page increased the subject count. Where did you host your experiment and how did you advertise it? 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? Today's computers have multiple network interfaces (LAN, W-LAN, etc.). 0.0.0.0 indicates that the first interface (computer.ipaddress.1) on a given computer (e.g. LAN card) was not assigned an IP address. computer.ipaddress.2 might have returned something else. 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... Not directly. You would have to apply much of the same strategies as in https://www.millisecond.com/support/docs/v3/html/howto/interopsurveys.htm, i.e., use query parameters. 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? Not sure, but might be related to (1). Also not sure what exactly you consider the "ending page". Regards, ~Dave

Group: Forum Members Posts: 13, Visits: 5	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
