Answer to Question 1

Speed of data collection--for door-to-door interviews it is moderate to fast and very fast for telephone interviews.

Geographic flexibility--limited to moderate for door-to-door interviews and high for telephone interviews.

Respondent cooperation--good for both types but better for door-to-door interviews.

Questionnaire length--can be long for door-to-door interviews but only moderate in length for telephone interviews.

Answer to Question 2

B
Determining the underlying structure of a set of variables is a use of factor analysis, not discriminant analysis.
