Likert Scale scoring – can I assign negative scores?
I am going to conduct a survey with a 4-point Likert scale. The questions are divided into headers. The responses will be scored and each header will be given a score.
I would like to know if its ok to assign negative scores to the Likert scale E.G.:
Strongly Agree: 2
Agree: 1
Disagree: -1
Strongly Disagree: -2
or should i just go with positive numbers:
Strongly Agree: 4
Agree: 3
Disagree: 2
Strongly Disagree: 1
I would like to know which one is a better practice and what are the implications of each method.
