I'm currently struggling to find a appropriate method to analyze my experiment.
Currently, I have 4 groups of subjects, and each subjects made a choice between 3 options(A or B or No choice). Below table shows a portion of my data.
My hypothesis is that, being in group 4 makes subjects shift choice from B to A. But I'm confused because there's 4 groups on a single category of independent variable and they're not ordinal.
Will it be right to shift my data as below..
..and use (multinomial) logistic regression to predict choice (A or B or Nochoice) from group number? I am thinking of seeing the effect of "being on group4" on increase of number of A choices in baseline of reference to choice B.
