    Score methods




    Hello everyone, I would like your opinion. my data is score (before and after therapy) on radiographs made with x-ray instrument and score based on the judgment of the doctor. I thought I create a new variable which only highlights the improvements, understood as the positive difference between the scores before and after therapy (with x-ray instrument and the doctor's judgment). after which I created a contingency table and used the chi2 and v-cramer to highlight the correlation between the two methods.
    there are more appropriate methods? Thanks for the attention

    What is you reserach question, what do you want to achieve?

    How many subjects were scored? How many doctors were involved?

    How do the scores actually look like, on which scale were they measured?

    With kind regards
