How to randomise participants to either the control group or the experimental group questions, but they also need to be stratified according to group. I.e. Qualtrics needs to access a common data base, and participants of a specific type (e.g. female, no association to an FGM practising country - determined by whether they say one of their parents was born from a practising country as per drop down list) then access a particular record in the data base based on the order in which they log on. To illustrate, e.g. females with no association to a practising country. Let's number them based on when they log on, e.g. 1, 2, 3, . . . For 1 and 2, flip a coin to see which list 1 gets. Force 2 to the get the opposite list. For 3 and 4, flip a coin to see which list 3 gets. Force 4 to get the opposite list. Etc. Do the same for the other three categories of participant. ANY help would be much appreciated! Thank you.
Hi, Anyone know how to randomise a block of questions based on the order of randomisation of the previous block? The second block of questions need to be presented in the same order as those of the previous randomised block. Support team can't seem to help with this. Would very much appreciate any help? Best, Fatoumata
