I made an experiment about UX where the participant has to detect among five differents configurations the one that he prefers. The configurations are slightly different and are presented randomly 3 times during the pre-test and 3 times during the post-test. I have two groups (Control and Experimental). The experimental group follows a training of 10 trials that aims to change perception about the configuration. I want to see if the training has an impact on participant's perception.
I would like to know how I can compare the two groups (Control and Experimental) to know if the training had an impact on the choices they made.
Thanks for the help !
