Why do studies conducted in theory-testing mode de-emphasize ecological validity?
Ecological validity is not very important
. Internal validity is the highest priority for theory-testing. Testing a theory never requires realism.
Which of the following claims is always in generalization mode?
Which of the following claims is always researched in generalization mode?
Frequency claims
. when researchers work in this mode, they want to generalize the findings form their study to a larger population.
Which of the following is an advantage of studies that are conducted in real world settings?
Which of the following is an advantage of studies that are conducted in real-world settings?
They are high in ecological validity
.
What does it mean if a study Cannot be replicated by an independent researcher?
What does it mean when a study cannot be replicated by an independent researcher?
The replication was done incorrectly
. Meta-analyses can examine conceptual and direct replications.
Which of the following claims is most likely to have been tested in generalization mode?
Frequency claims
are almost always in generalization mode. Association and causal claims are only sometimes in generalization mode. Causal and association claims use theory-testing mode more than generalization mode because internal validity is more important than external validity within these claims.
What are the two main reasons to conduct a factorial study?
What are two reasons to conduct a factorial study? –
They test whether an IV effects different kinds of people, or people in different situations in the same way
. -Does the effect of the original independent variable depend on the level of another independent variable?
Why is it important for researchers to be able to replicate a study?
When studies are replicated and achieve the same or similar results as the original study, it gives greater validity to the findings. If a researcher can replicate a study’s results, it means that
it is more likely that those results can be generalized to the larger population
.
What is the difference between internal and external validity?
Differences. The essential difference between internal and external validity is that internal validity refers
to the structure of a study and its variables
while external validity relates to how universal the results are.
What is theory testing mode?
Theory-testing mode.
A researchers intent for a study, testing association claims or causal claims to investigate support for theory
. Generalization mode. The intent of researchers to generalize the findings from the samples and procedures in their study to other populations or contexts.
What is the purpose of replication studies quizlet?
describing a study whose results have been reproduced when the study was repeated, or replicable
. no other studies received the same received. Replication gives a study credibility, and it is a crucial part of the scientific process.
What does it mean to replicate a research study?
A replication study is a study that
is an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances
.
14
. Clearly, this definition requires some explanation.
What are the two types of quantitative research?
In general, there are 2 types of quantitative research;
exploratory research and conclusive research
. Conclusive research consists of descriptive research and causal research.
Why is replicability important?
It is very important that research can be replicated, because it means that other researchers can test the findings of the research. Replicability
keeps researchers honest
and can give readers confidence in research. … If the research is replicable, then any false conclusions can eventually be shown to be wrong.
Which of the following is a major limitation of case studies?
One major limitation of case studies is that
it is often difficult to generalize findings from the individual studied to other individuals
. If you are interested in uncovering cause-and-effect relationships between two variables, you would use the correlational method.
How do you know if a study is internally valid?
- Your treatment and response variables change together.
- Your treatment precedes changes in your response variables.
- No confounding or extraneous factors can explain the results of your study.
What are the four Validities?
These four big validities–
internal, external, construct, and statistical
–are useful to keep in mind when both reading about other experiments and designing your own.
