Final: Chapter 5 Flashcards
What is the research process?
Generating further research
Research problem and purpose
Review of relevant literature
Study framework
Research objectives, questions, or hypotheses
Study variables
Population and sample
Measurement methods
Data collection
Data analysis
Discussion of research outcomes
is an area of concern in which there is a gap in the knowledge needed for research practice
research problem
- significance
- background
- problem statement
is a clear concise statement of the specific goal or focus of a study
research purpose
what are some sources of research problems?
nursing practice
researcher and peer interaction
literature review
theory
research priorities
qualities, properties, or characteristics of people, things, or situations that are manipulated or measured in research
variables
variables are measurable with __________ and/or intensity ________.
instruments
scales
what are the types of variables?
independent
dependent
research variables or concepts
extraneous
demographic
what are independent variables?
the stimulus or activity manipulated or varied by the research to cause an effect on dependent variables
it is also called the treatment or experimental variables
the independent variable causes the dependent variable to change
the independent variable does not change - it is controlled by the researcher
what are dependent variables?
the outcome or response the researcher wants to predict or explain
changes in the DV are presumed to be caused by the independent variable
what are extraneous variables?
they can interfere with obtaining clear understanding of relational or causal dynamics in the study
they can be recognized or unrecognized and controlled or uncontrolled
is the variable is not recognized until the study is in process or cannot be controlled, it is called a confounding variable.
an environmental variable is an uncontrolled variable relating to the setting
what are the types of hypotheses?
associative vs. casual
simple vs. complex
non-directional vs. directional
null vs. research
relationship between variables
associative hypothesis
cause and effect relationship between variables
casual hypothesis
relationship exists between variables, but hypothesis does not predict nature of relationship
non-directional hypothesis
nature (pos or neg) of interaction between 2 or more variables is stated
directional hypothesis
