More accurate information: An interviewer is able to get the exact thoughts and feelings of the person being interviewed, instead of just a single answer.
Can be stored for later use: If a computer saves too much data it will eventually run out of space.
Lower cost: It may be cheaper to buy writing materials rather than buying computers
Disadvantages:
It is hard, tiring work: Most people prefer to sit at a computer and type all day rather than to run around interviewing thousands of people in a day.
Lack of space: It takes less space to save documents on a computer than to file millions of papers.
Speed: Sometimes it takes a long time to type information into a computer.
