$1.$ Both interviews and surveys consist of questions devised by the researcher along with the customer's attempt to answer these questions. In terms of distinctions between the two, in the one, the questions are spoken, without too much "version control" $($i$.$e$.,$ many differences in wording across interviews$),$ while in the other, question wording is fixed. Another difference is that interviews are generally few in number, surveys many.

$1.$ What else is similar across interviews and surveys, and what else is different?

$1.$ In your answer, please assume a self$-$administered web survey, and an in$-$person interview.

$2.$ Is there a kind of question that can only work in surveys, or can anything that can be asked in a questionnaire also be asked out loud in an interview?

$3.$ Same question in reverse: Are there questions that "work" in an interview, but would not work when written down in a questionnaire?

$2.$ One of the ways to conceptualize a process that takes place in time, such as an interview, is to divvy it up into a beginning, a middle, and an end.

The middle occupies the bulk of the time and, of course, fulfills multiple purposes; but beginnings and endings may have a more specialized function. Assuming this to be a useful conceptualization, answer the following questions:

$1.$ What is the primary function of the beginning of the interview? What actions or types of questions have to be avoided at the outset of an interview, if that function is to be fulfilled? What particular actions and questions would be notably helpful and useful?

$2.$ What function$($s$)$ have to be performed at the conclusion of an interview? What actions or types of question should be avoided here?

What particular actions and questions would be notably helpful and useful at the end of the interview?
