- Make sure it is low in psychological realism.
- Conduct the study in the laboratory instead of the field.
- Replicate the study with a different population of people in a different setting.
- Make sure you have at least two dependent variables.
Which of the following is the best way to increase the external validity of a study group of answer choices?
- Make sure it is low in psychological realism.
- Conduct the study in the laboratory instead of the field.
- Replicate the study with a different population of people in a different setting.
- Make sure you have at least two dependent variables.
How can external validity be improved in a study?
Some researchers believe that a good way to increase external validity is by
conducting field experiments
. In a field experiment, people's behavior is studied outside the laboratory, in its natural setting.
How can you improve external validity quizlet?
- identify the variable of interest to the researcher (IV), and the levels (groups or conditions)
- Look for any difference between groups or conditions other than the IV that could potentially account for a difference in the results.
Which of the following best defines external validity?
External validity refers to
how well the outcome of a study can be expected to apply to other settings
. In other words, this type of validity refers to how generalizable the findings are.
What is an example of external validity?
External validity is another name for the generalizability of results, asking “whether a causal relationship holds over variation in persons, settings, treatments and outcomes.”
1
A classic example of an external validity concern is
whether traditional economics or psychology lab experiments carried out on college
…
What affects internal and external validity?
Internal validity is
the degree of confidence
that the causal relationship you are testing is not influenced by other factors or variables. External validity is the extent to which your results can be generalized to other contexts. The validity of your experiment depends on your experimental design.
What are the elements of external validity?
In sum, external validity covers at least four aspects of experimental design:
whether the participants resemble the actors who are ordinarily confronted with these stimuli, whether the context within which actors operate resembles the context of interest, whether the stimulus used in the study resembles the stimulus
…
What can affect external validity?
There are seven threats to external validity:
selection bias, history, experimenter effect, Hawthorne effect, testing effect, aptitude-treatment and situation effect
.
What is the difference between external validity and generalizability?
External validity is a function of the researcher and the design of the research. Generalizability is
a function of both the researcher and the user
.
What is the difference between internal validity and external validity quizlet?
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.
Why is internal validity more important than external validity?
Internal validity
ascertains the strength of the research methods and design
. Conversely, external validity examines the generality of the research outcomes to the real world. Internal Validity determines the extent to which the conclusion is warranted.
What refers to external validity quizlet?
External Validity. Refers to
the extent to which the results of a research design can be generalized beyond the specific way the original experiment was conducted
.
What increases external validity?
How can we improve external validity? One way, based on the sampling model, suggests that
you do a good job of drawing a sample from a population
. … That is, your external validity (ability to generalize) will be stronger the more you replicate your study.
How do you determine external validity?
Results External validity refers to the question whether results are generalizable to persons other than the population in the original study. The only formal way to establish the external validity would be
to repeat the study for that specific target population
.
What are the different types of validity?
- Construct validity: Does the test measure the concept that it's intended to measure?
- Content validity: Is the test fully representative of what it aims to measure?
- Face validity: Does the content of the test appear to be suitable to its aims?
