I'm currently analyzing my experimental data and I have a question about comparing two variables. In the experiment I have a question which asks respondents to rank a set of pictures based on their preference from first to last (1 to 6 ranking). The respondents are then presented with some information (as condition) and need to assess again the pictures they were presented with initially. This time however they need to rate every picture on an evaluation scale from 1 to 7. My question now is whether I can compare the ranking and rating score of the pictures in order to see whether the provided information had any effect on the evaluation of the pictures. Is that possible, any suggestions??
