What is the purpose of correlational studies?
Answer research questions that seek to link or connect.
243
What is a pre-test post-test experimental design?
Involves manipulation of the independent variable, random assignment, and a control group. Also includes an observation both before and after the intervention.
244
What is 'multifactorial'?
Several independent variables being manipulated in a study
245
What is a quasi-experimental design?
Lack control or random assignment.
246
Quasi-experimental studies lose ______ of an experimental design but gain ______ to real life
Internal validity, applicability.
247
What is inductive knowledge?
Developed by pulling observations and facts generated through research together to generate theory. Pieces to build a whole theory.
248
What is deductive knowledge?
Developed by proposing a theory regarding a phenomenon of interest. Starts with the whole and breaks down the parts of the theory.
249
What is a theoretical framework?
Abstract aspects of the research problem interrelate based on developed theories
250
What is a conceptual framework?
Underlying structure, but it comprises concepts and the relationships among them.
251
_____, _____, and ______ all provide a description of the proposed relationships among abstract components that are aspects of the research problem of interest
Theory, theoretical frameworks, and conceptual frameworks
252
The terms ______, ______, ___, _______,or _______ all refer to the statement of the variables to be studied that are related to the broad research problem
Research purpose, research question, study, specific aim(s), or research objectives
253
The literature review is....
Guided by variables that have been identified in the research purpose to give the reader an overview of what is known about these variables, how those variables have been studied in the past, and with whom they have been studied
254
What are primary sources?
Sources of information as originally written.
255
What is a secondary source?
Someone else's description or interpretation of a primary source.
256
What is peer review?
Means that the manuscript for the published report has been read and critiqued by two or more peers before being accepted for publication
257
What the difference between research question and hypothesis?
Hypothesis: puts the predictions in the form of a statement. Question: puts the predictions in the form of a question.
258
What is a directional hypothesis?
Predicts that two variables will be related and as well predicts the direction of that relationship
259
What is a nondirectional hypothesis?
Predicts that two variables will be related but does not predict the direction of that relationship.
260
Are the steps of the research process linear?
No. They may overlap or be revisited during the research process.
261
What are assumptions?
Ideas that are taken for granted or viewed as truth without conscious or explicit testing.
262
In research, what is a codebook?
Record of categorization, labeling, and manipulation of data about variables in a quantitative study
263
What is aggregated data?
Results from the study are reported for the entire sample rather than for individual members in the group.
264
What are 4 characteristics of the research process?
Systematic, exacting, complex, challenging.
265
What are factors affecting the research process?
Lack of knowledge, lack of resources (money, time, or both), and lack of methods or measures.
266
What is a pilot study?
Small research study that develops and demonstrates the effectiveness of selected measures and methods.
267
What is the difference between the purpose of the research process and EBP?
RP: purpose to develop knowledge.
EBP: to provide scientifically based care.
268
What is epistemology?
To know
269
What is ontology?
To be
270
What is practice?
To do
271
What is a nominal variable?
NO numbers. Ex. yes/no
272
What is an ordinal variable?
Variables in order, ranking order. Ex. 1st, 2nd, 3rd.
273
What is an interval variable? What is this type of variable commonly used for?
Equal distances between variables on a tool or scale. Example: thermometer. Opinions/attitudes like preassigning numbers for pain rating.
274
What is a ratio variable?
Absolute 0. Either you have it or don't have it.
275
What is the most rigorous variable?
Ratio variable
276
What variables are involved in parametric data? Assumption or no assumption about population?
Ratio, interval. Assumption about population.
277
What variables are involved in non-parametric data? Assumption about population?
Nominal, ordinal. No assumption about population.
