Qualitative research - Correct answer✅✅ Systematic approach used to describe experiences and
situations from the perspective of persons in the situation
What does the researcher analyze during qualitative research? - Correct answer✅✅ The words of the
participants, the meaning in the words, and provides a description of the experience that promotes
deeper understanding of the experience
What are the four commonly used qualitative research used in nursing? - Correct answer✅✅
Phenomenological research
Grounded theory research
Ethnographic research
Exploratory-descriptive qualitative research
Where is qualitative resear - Correct answer✅✅ Natural settings to learn about a topic from the
perspective of the participants
What kind of data is qualitative data? - Correct answer✅✅ Words and images
Quantitative research - Correct answer✅✅ Formal, objective, rigorous, and systematic process for
generating numerical information about the world
Why is quantitative research conducted? - Correct answer✅✅ To describe new situations, events, or
concepts, examine relationships among variables, and determine the effectiveness of interventions on
selected health outcomes
Example: Describe the spread of flu caes each season and their potential influence on local, national,
and global health - Correct answer✅✅ Quantitative research
, Example: Examining the relationship among the variables, such as minute watching television per week,

What happens in an experimental study? - Correct answer✅✅ Causality between the independent
and dependent variables is examined under highly controlled conditions
Three main characteristics of quantitative research - Correct answer✅✅ 1. Controlled manipulation
2. Exposure of some of the study participants to the treatment and no exposure to the remaining
participants
3. Random assignment of participants to the control or experimental group
Correlational research - Correct answer✅✅ Involves the systematic investigation of relationships
between or among variables
What happens when conducting correlational research? - Correct answer✅✅ Researchers measure
selected variables in a sample and then use correlational statistics to determine the relationship among
the study variables
Cross-sectional design/research - Correct answer✅✅ Involves data collection on variables at one point
in time
Example: Examining a group of study participants simultaneously in various stages of development,
levels of education, severity of illness, or stages of recovery to describe changes in a phenomenon across
