Designing a Response Scale to Improve Average Group Response Reliability
Davies, Randall
Evaluation and Research in Education, v21 n2 p134-146 2008
Creating surveys is a common task in evaluation research; however, designing a survey instrument to gather average group response data that can be interpreted in a meaningful way over time can be challenging. When surveying groups of people for the purpose of longitudinal analysis, the reliability of the result is often determined by the response scale used. Likert scales and numeric continua are commonly used for this purpose. Both scales are relatively easy to create and both have distinct advantages and disadvantages. This paper reports the findings of a project to combine a fully anchored Likert scale with a numeric rating scale. The resulting scale for a follow-up survey utilises fixed anchor points along with visual cues to provide a layer of direction for the respondents; it also uses a numeric continuum to elicit a second layer of information that is more discriminating. The results are both easily interpreted on the original scale and are more appropriate for longitudinal comparison purposes both in terms of obtaining reliable results and in the scale's ability to identify changes in response over time.
