I'm trying to find out if certain factors matters more to people than other factors. I have five different factors and on a 5 point-likert scale, I have questions about which factor is more important to them compared to one other factor at a time (So 5 questions taken two at a time leading to 10 data columns). I want to use these 10 data columns to find out the general order of preference for these 5 factors. Should I be using the Friedman test or something else? Please help, I'm really confused about this.
