characteristics of quantitative research

A
  • formal, objective, rigorous, systematic process for generating information
  • describes new situations, events, or concepts

Q

causality

A

there is a cause and effect relationship between the variables

20
Q

multi-causality

A

a cause and effect relationship between interrelating variables

21
Q

types of hypotheses

A
  • associative vs. causal
  • simple vs. complex
  • nondirectional vs. directional
  • null vs. research
22
Q

associative vs. causal hypotheses

A
  • associative = relationship between variable (apples and oranges are both fruits)
  • causal = cause and effect relationship between variables (reusing needles after sterilizing)
23
Q

simple vs. complex hypotheses

A
  • simple = states the relationship (associative or causal) between two variable
  • complex - states the relationships (associative or causal) among three or more variables
24
Q

nondirectional vs. directional hypotheses

A
  • nondirectional = relationship exists between variables, but hypothesis does not predict nature of relationship
  • directional = nature (positive or negative) of interaction between two or more variables is stated
25
Q

null vs. research hypotheses

A
  • null = states there is no difference or relationship between variables; also called statistical hypothesis
  • research = states what researcher thinks is true; there is a relationship between two or more variables
26
Q

demographic variables

A
  • contain characteristics of subjects
  • age, education, gender, ethnic origin, income, medical diagnosis, geographic location, etc
27
Q

operational definitions

A
  • translating downward to more concrete level
  • moves from concept to variable measures
28
Q

in qualitative research, what are the people defined as?

A

a participant/collegue

29
Q

in quantitative research, what are the people defined as?

A

a subject

30
Q

five approaches to qualitative research

A
  • phenominological (study a phenomenon)
  • grounded theory (creating theories)
  • ethnography (culture)
  • exploratory-descriptive-qualitative
  • historical (data)
31
Q

phenomenological research

A
  • describes experiences as they are lived
  • in depth interviews with the participant
32
Q

grounded theory

A
  • purpose is to study a phenomena that contributes to theory development
  • useful when little is known on a topic
33
Q

ethnography research

A
  • observes and documents interactions within a culture
  • OBSERVATION
34
Q

exploratory-descriptive research

A
  • used to obtain information needed to develop a program or intervention for a specific group
35
Q

historical research

A
  • examine and learn from events of the past
36
Q

how does sample size differ in qualitative studies?

A

they are usually smaller, can be hand picked to participate, mostly everyone has experienced what the researcher is studying

37
Q

which intervention should be included in research designs that test causality?

A

carefully developed to provide the most effective treatment possible

38
Q

which element would you expect to see in an experimental study?

A

manipulation of the independent variable

39
Q

grounded theory is based on what belief?

A

group life is based on consensus and shared meanings

40
Q

why is bias a serious problem?

A

it distorts the study findings

41
Q

what research is conducted to generate and refine theory, and is frequently not directly useful in practice?

A

basic research

42
Q

A nurse researcher was studying the effect of a cardiac rehabilitation program on the heart rate, respiratory rate, and functional status of patients 2 months after a myocardial infarction. The study was conducted in the rehabilitation center where the researcher controlled the consistent implementation of the treatment. What type of setting was used for this study?

A

partially controlled

43
Q

Which are requirements for an experimental study?

A
  • random sampling
  • control group
  • control of the intervention
44
Q

What is the major purpose of the National Institute for Nursing Research (NINR)?

A

provide financial support to nursing research

45
Q

The new nurse researcher is comparing the difference between the rigors of qualitative research and quantitative research. Which components would be included in the rigor for qualitative research?

A

openness and adherence to the philosophical perspective

46
Q

A nurse researcher conducted a study with Becker’s health belief model as the framework for the study. The researcher failed to provide conceptual definitions for the variables. This is an example of what type of limitation?

A

theoretical

47
Q

The nurse researcher is conducting a lecture series on how to report research findings. The researcher begins with an overview of the four major parts most often included in a research report. Which of the following would be included in this overview?

A

introduction, methods, results, discussion
