Internal validity has to do with the accuracy of the results. Results could be inaccurate if samples are not selected randomly. External validity has to do with the generalizability of the findings to the population. If the sample selected is only Hispanics under the age of 25, then it would be hard to generalize the results to the entire US population.

What are threats to external validity?
"A threat to external validity is an explanation of how you might be wrong in making a generalization."[4] Generally, generalizability is limited when the cause (i.e. the independent variable) depends on other factors; therefore, all threats to external validity interact with the independent variable.
External validity in an experimental design refers to?
The ability to apply findings to other populations
What is administration of the instrument in research method?
Usability is what is referred to as the administration of the instrument in research method. Also, within the research method, you will find validity and reliability.
It is important to rely only on one source when you are researching a scientific issue?
Its important not to!! You need to get info from multiple sources for any validity in your research.

Examples External validity and internal validity in research?

If you gain internal validity do you lose external validity?
If you gain internal validity do you lose external validity
What is the difference between internal and external validity?
The difference between internal and external validity is in their nature. Internal validity indicates if a study depicts relation between two variables. External validity on the other hand generalizes the study of the variables.
Is it easier to increase internal validity than external validity?
No it is not easier because of the external flow.
Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.
Compare and Contrast Internal validity vs external validity?
Internal validity is the degree to which the results are attributable to the independent variable and not some other explanations.External validity is the extent to which the results of a study can be generalized.
What are threats to validity in epidemiological studies?
The main threats to validity are bias, confounding and chance. But keep in mind the internal and the external validity. Internal validity is the extent to which systematic error is minimised during the stages of data collection. where as the external validity encompasses the extent to which the results of the trials provide a correct basis for generalisation.
Differentiate between external validity from internal validity?
External validity is the extent that results from a study generalize to other people, places, and situations--how well the findings stand outside the study and the extent to which they can be replicated. The internal validity is that extent to which the study's design enables it to measure and study what it intends to study.
When the finding of an experimental research are generalized to target population the research is said to possess?
External validity
How internal validity of the correlational research can be increased?
By ruling out a series of threats to that validity. Please see the link for a list of them.
How reduce threats to internal and external validity in experimetal research?
There are a number of ways to reduce threats to validity:By arguing against the threatBy observing and measuring the threat.By analysisBy preventive actionBy design.
What means validity in research project?
It means reliability or truthfulness and can be applied to the purpose of the project, to its design or, most often, to the results of the research. If the results of a research project are valid it means they are accurate, true, sound or just and believable. If the results are not valid then they are inaccurate, untrue, unsound or unjust and should be ignored.
