▫ What is the most important attribute in a job?

▫ Do you think that, Brazil played poorly in the FIFA
cup ?

agree with one part of the question, but not
agree with the other or cannot answer making a
particular assumption.
• Example:
▫ Are you happy with the price and quantity of
branded shampoo?

answers to the respondents.
• Example:
▫ Do you like the programme on Radio Mirchi?
▫ Answer would likely to be Yes
▫ Which is your favourite F.M. Radio station?

on the topic. This is known as funnel sequence.

▫ To add or remove questions arise in the process of pretest, if any.
▫ To purge the words with double meaning, etc.
