I have used the following Likert scale for a series of questions in a survey:
- 0 = Not Important
- 1 = Slightly Important
- 2 = Moderately Important
- 3 = Very Important
- 4 = Extremely Important
As I understand it, this is a 5 point Likert scale. (Unsure, though!)
I have then used a weighting formula that has resulted in final (composite) scores as follows: 0.2, 1.4, 2.3, 3.4, 4.6, etc.
Example: If a person has indicated "moderately important" to three questions, it is 2 + 2 + 2 = 6. I have then multiplied 6 by a constant e.g. 6 x .33 = 1.98. The constant is derived from theory and represents percentage contribution of a variable.
- How do I represent the composite scores on the above Likert scale (i.e. what does a score of 1.98 mean?)
- Is it possible for composite scores to be greater than the last category e.g. if a a person has chosen 'extremely important" for four questions, it is (4 + 4 + 4 + 4 = 16) x .33 = 5.28?
- When we talk about a 5 point Likert scale, do we mean the distance between the response categories (e.g. between 0 and 1 or 1 and 2 on the above scale) or just the category numbers (e.g. 0, 1, 2, 3, 4)?
