Survey Scale definition:
In common survey usage, a scale is an ordered series of response options, presented verbally or numerically from which the respondents select to indicate their level of feeling about the measured attribute. More properly a scale is a composite score of a number of survey questions that each measure the same attribute.
Types of survey scales:
- Dichotomous Scales
A dichotomous scale is a two-point scale which presents options that are absolutely opposite each other. This type of response scale does not give the respondent an opportunity to be neutral on his answer in a question.
Yes - No
True - False
Fair - Unfair
Agree - Disagree
- Rating Scales
Three-point, five-point, and seven-point scales are all included in the umbrella term “rating scale”. A rating scale provides more than two options, in which the respondent can answer in neutrality over a question being asked.
- 1-10 scale
- 1-7 scale
- Likert scale (1-5)
- Semantic Differential Scales
A semantic differential scale is only used in specialist surveys in order to gather data and interpret based on the connotative meaning of the respondent’s answer. It uses a pair of clearly opposite words, where the respondent is asked to rate an object, person or any concept by putting a mark on one of the spaces along each dimension.
Examples of an semantic differential scale:
Inexpensive [ ] [ ] [ ] [ ] [ ] Expensive
Effective [ ] [ ] [ ] [ ] [ ] Ineffective
