PR exam Flashcards
The primary purpose of an experimental research design is to find out?
whether an
intervention considered as the independent variable (e.g., lack of sleep) has an effect on a
dependent variable
are empirical, straightforward, and can test their reliability and validity?
Quantitative research designs
observes a situation and attempts to establish what caused
b. Non-Experimental Design
an assumption of a cause-and-effect relationship
Experimental Design
The three most common
types of quantitative research designs are?
experimental, correlational, and descriptive?
a scheme or plan of action for meeting the objectives of the study
Research design
most commonly – used method of investigation in educational research
Descriptive Design
philosophical, theoretical, conceptual and analytic perspective of research; can be qualitative, quantitative or mixed method
Research Method
philosophical, theoretical, conceptual and analytic perspective of research; can be qualitative, quantitative or mixed method
Research Method
first step in creating structure to the design; details a conceptual model or framework on how the research will proceed; consider objectives and variables
Approach
plan, structure and strategy of investigation to obtain answer to research q or problems
Complete scheme or program; an outline of what to do from writing the hypothesis to operational implications to final analysis of data (Kerlinger, in Kumar, 2011)
Design
depend largely on the philosophical perspective, objective of the study, the inquiry mode, and the applicability of research findings.
Research Design in Quantitative Method
- commonly used in the social sciences
- aim to find out the prevalence of a situation by taking a cross-section of the population
Cross-sectional studies
- measure change
The before and after design (pre-test/post-test)
determine the pattern of extent of change in a situation in relation to time
Longitudinal Study Design
– investigate what has happened in the past
Retrospective study design
attempts to establish the outcome/what is likely to happen in the future
Prospective study design
available data are analyzed as bases of future projections
Retrospective-prospective study design
an assumption of a cause-and-effect relationship
Experimental Design
– has both experimental and non-experimental properties
c. Semi-Experimental / Quasi-Experimental
results of a survey serve as basis for establishing inferences; provides a reference point for analysis classification and evaluation
Descriptive- survey research design
if the study is to see a general picture of the population under investigation; to use when the investigator wishes to cover a relatively large population
Survey
complete enumeration; covers entire population under investigation
Census
complete enumeration; covers entire population under investigation
Census
