Between-groups randomization online

Group: Forum Members Posts: 5, Visits: 22	Hi there, Background Info: I have created 1 script with three different tasks within the script: An IAT (experiment 1), another responding task (experiment 2), and some "slider"/"textbox" questions (experiment 3). Participants will firstly use the university webpage/platform to answer some questions, then will be directed to Inquisit for the responding tasks, and thereafter will be re-directed to the university webpage. Participants' get a session identity (created by the university webpage e.g. looks like Ms8M43W621olz1Yg1b2A15p2Q60x5T70l5N98jod5D54hN745am6Pb). Within my script, I want to randomize between-groups so that Group 1 does the sequence of experiments 1,2,3 and Group 2 does the sequence of experiments 2,1,3. It seems that the batch option is not a good one, as I can only load 1 file/experiment at a time (and as I understand, for a batch I would need to upload 3 different experiments and the batch command file online). Question: Which command is best to randomize participants into these 2 groups (as stated above) if I only upload 1 script/file onto the web? Kind Regards,

This is incorrect. You can use <batch> elements just fine and you only need a single license. Create a file containing the two <batch> elements representing the two different orders. The file containing those <batch> elements is the one you ought to register as your active web script. <batch> / file = "1.iqx" / file = "2.iqx" / file = "3.iqx" / subjects = (1 of 2) / groupassignment = groupnumber </batch> <batch> / file = "2.iqx" / file = "1.iqx" / file = "3.iqx" / subjects = (2 of 2) / groupassignment = groupnumber </batch>
