How to do that?<br/>Thx for any advices!Mon, 30 May 2016 16:31:47 GMTgootralhttps://forums.millisecond.com/Topic19179.aspxSuppose the two blocks you want to randomize are called a and b. Then you simply do:<br/><br/>&lt;expt&gt;<br/>/ blocks = [1=demographics;<strong> 2-3 = noreplace(a,b)</strong>]<br/>...<br/>&lt;/expt&gt;<br/><br/>You'll find this covered in the documentation for the &lt;expt&gt; element's /blocks attribute. In general, randomizing blocks in an experiment works the same way as randomizing trials in a block.<br/>Mon, 30 May 2016 16:31:47 GMTDave
