How do I combine 8 different items into one variable, so that we will have 6 variables, using SPSS?
I have used a 48 item questionnaire – a Likert scale – with 5 points (strongly agree – strongly disagree). The questionnaire contains 6 categories and each category has 8 questions. 8 items correspond to one variable which means that we have 6*8 = 48 questions in questionnaire.
