Experimental Research
The notation for this design is
R O X O
R O O
What is basic experimental design?
A researcher uses a specific innovative teaching method with one section of a course and uses the traditional teaching method with the other section of the class. This is what type of design?
What is: Alternative Treatment Design with pretest
Another way to refer to non-experimental designs, which are often used to characterize a phenomena or examine a relationship between variables.
What is pre-experimental research?
P is < 0.05
What is probability level?
or
What is confidence level?
A researcher is concerned with whether or not a studies results are generalizable to a similar group or to the population.
What is external validity?
This type of design is used when the researcher is unsure of the impact of the pre-test on participants but believes the pre-test provides pertinent information to the study.
What is Solomon four-group design?
R O X O1
R O O2
R X O3
R O4
This type of design occurs over a period of time and the experimental group acts as it's own control group.
What is times-series design?
An OTR working in the school system is interested in determining the relationship between hours of sleep at night and academic performance in high school students.
What is correlational research?
A general term that refers to the likelihood that relationships observed in a sample could be attributed to chance (sampling error) alone.
What is: statistical significance
A researcher wanting to ensure that a study's sample has an equal opportunity to be in the experimental group as in the control group should use _____________.
What is random assignment?
What is single-blinded randomized control study (RTC) ?
A researcher designs a study when research participants all receive the treatment and then experience a period of time that they do not receive the treatment.
What is one-group pre-test-post-test design?
or
What is quasi-experimental lacking control?
A nurse is working at an inpatient acute rehabilitation facility and collects information on one patient with Parkinson's disease over a period of 3 weeks.
What is quantitative case study research?
This has to be rejected if the value of the independent variable is to be validated.
What is: null hypothesis
A researcher attempts to eliminate any irrelevant influences on a study's design.
What is control?
This experimental design tests not only whether the intervention is effective but also which components of the intervention may or may not be necessary to achieve its effects.
What is: Dismantling studies
This type of research design is MOST APPROPRIATE when a researcher wants to study naturally occurring situations or it is unethical to use a control group.
What is quasi-experimental?
Studies in which the dependent variable has already occurred for example a disease or disability are considered _______________
What is retrospective?
Method of analyzing the simultaneous relationships among several variables.
What is: Multivariate Analysis
Two social workers adminster the same assessment to one person and compare scoring/results.
What is interrater reliability?
What type of research design does this notion indicate?
R O X O1 O2
R O O3 O4
What is pre-test - post-test design with follow-up?
The primary difference between quasi-experimental and experimental design
What is: randomization
An social worker sent out a questionnaire to individuals with rheumatoid arthritis (RA) to determine the impact of RA on quality of life.
What is survey research?
Study results that reflect a p-value of .08 would be considered...
What is: lacking statistically significance
These are the 4 levels of measurement.
What is nominal, ordinal, interval and ratio
