I have developed a scale, and I want to know how to score the responses. What is the procedure to decide whether we have to start from 0 or 1 for each item?
You need to range the numerical values, and they could range from 1-5.
For example, if the total respondents are 40 and the scale range could be
1= strongly disagree,
3= somehow agree,
4= agree and
5= strongly agree,
Go to google and search, Krosnick & Presser 10 Survey Design.pdf there you will find a useful paper by two experts in survey question writing.
It will really help you.
