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 ?
