While collecting primary data with the help of a structured questionnaire, which is the best way to collect information on income/saving/expenditure? For ex:
1. Amount spent on the purchase of health insurance (if any)
A. Zero
B. 1-2500
C. 2501-7500
D. 7501-15000
E. 15001-30000
F. More than 30000
2. Amount spent on the purchase of health insurance (if any) ________________ (open ended)
Considering the sample size of 1000 + and more such questions (mix of likert scale, multiple choice, checkbox), which will be the most convenient and reliable question to follow ? Either Question 1 or Question 2.
Your answers will be of great help to me.
Thanks
