Answer to Question 1

A

Answer to Question 2

B
Feedback:
Qualitative research, like quantitative research, can be either cross-sectional, with one data collection point, or longitudinal, with multiple data collection points designed to observe the evolution of a phenomenon. Qualitative research is almost always nonexperimentalalth ough a qualitative substudy may be embedded in an experiment (see Chapter 18). Qualitative researchers do not conceptualize their studies as having independent and dependent variables, and they rarely control any aspect of the people or environment under study. Blinding is rarely used by qualitative researchers. The goal is to develop a rich understanding of a phenomenon as it exists and as it is constructed by individuals within their own context.
