Experimental groups A/B test

Question

Hi,

sorry if this was already asked but all answers are in german, that does not help me a lot.
I have to make survey with 2 experimental groups and with 2 stimulus (2 simple pictures with text).
50 participants have to see picture1 and 50 participants picture2. Afterwards they all have to answer exactly the same questions.
I know it should be simple but writing even a simple code is a nightmare for me.
Could you please help me or share some tutorial ?

Greets,

Thank you

This is explained step-by-step in the manual Randomization. If you have already read this manual, could you please specify how far you got and what does not (yet) work?
