A procedure in which questions are adjusted in accord with the answers the interviewee provides.

Question 27

Naturalistic Observation

Answer 27

Examination of ongoing behavior in an environment not controlled by the researcher

Control Group

Answer 38

The group of participants in an experimental design who are not presented the experience of interest but in other ways are treated similarly

Question 39

Independent Variable

Answer 39
