approaches available today
Approaches Available Today
  • Likert Scales
    • Respondents rate each item on a 5, 7, or 9-point scale.
  • Constant Sum
    • Respondents divide a given sum (usually100) among two or more items.
  • Ranking
    • Respondents rank the items in order.
  • Max-Diff
    • Respondents are shown subsets of the items and asked to specify best/worst for each set.

Pros And Cons Of Each Approach

Likert Scales

Constant Sum

  • Pros
    • Easily administered
    • Easily understood by respondents
  • Cons
    • Heavily influenced by scale use bias
    • Difficult to discern true differences between countries
  • Pros
    • Forces trade-offs
    • Avoids yea-saying
  • Cons
    • Difficult to administer if there are more than 5 items
    • Programming does not work on all browsers if done by web

Ranking

*Max-Diff

  • Pros
    • Each point is used only once
    • Easily understood by respondents
  • Cons
    • Influenced by order bias
    • Does not allow ties
  • Pros
    • No scale use or order bias
    • Provides better discrimination among items
  • Cons
    • Data is relative not absolute
    • Takes slightly longer to implement

*Max-Diff is the preferred approach when looking for differences across countries and when relative difference is important.

  • Step 2: Put items into pre-defined tasks of 4. In this case we are testing12 items. To complete the exercise respondents will need to complete 9 of these tasks.

Tasks 1-9

○ Item C ○

○ Item F ○

○ Item A ○

○ Item H ○
