We are doing an undergraduate study using scale response questions with a Media Lab questionnaire about brand preferences. The questions are counterbalanced in a way that sometimes 1 is the right answer and other times 2 is the right answer. For example for certain questions 1 indicates the brand while other times 1 indicates generic items so there is not a consistent formula where each number corresponds to the same thing. We are using SPSS to calculate data and we are having a problem because the labels of 1 (top box) and 2 (bottom box) are all Media Lab reports but they stand for different things. We want a way to add up how many times people chose the brand, it would be ideal for the brand to equal a 1 and generic to be a 0 in regards to point value. How do we program Media Lab to this? Or can you suggest another approach?
