Running a random group assignment with a Survey page?

Hi there! I am currently trying to program a measure for part of an experiment.  I created the measure as surveypages because I need radiobuttons for participants to respond to the questions, however, I want to randomly assign participants to different groups that will receive slightly different instruction pages, everything else in this experiment is the same for all participants.  Should I create a separate script for just the instruction page?  If so, does anyone know how I can program the instruction pages to appear in the expt or block elements?  Thank you so much!

There are tons of ways to do this. Whatever works best depends on what exactly you want.


Remember:


- Between-subjects conditions are implemented via multiple <expt> elements and/or the <variables> element. Pay special attention to the /subjects and  /groupassignment attributes in the documentation.


- A <surveypage> is a special kind of <trial>. It can be run via a <block>'s /trials attribute.


- A <survey> is a special kind of <block>. It can be run via an <expt>'s /blocks attribute.


- Inquisit *does not* record any data for instruction pages, that is anything presented on a <page> or <htmlpage> and presented via /preinstructions or /postinstructions.


- If you need to log data for your "instructions", use standard <text>, <trial>, etc. elements to display them.
