between two variables.
Quantitative research is concerned with the subjective assessment of attitudes of a Customer.
Closed ended questions are more useful in exploratory research.

The airline industry in India is expected to have a strong market potential.

four prominent reasons according to you.
Would you suggest a survey to understand the attitude of the air travellers towards the rates or
services of the company?
