Examples External validity and internal validity in research?
examples of internal and 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.
What is Causal Validity?
Causal validity is also referred to as internal validity. It refers to how well experiments are done and what we can infer from those results.
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.
What is the most serious threat to internal validity in a nonequivalent control group design?
rice fields are turned into residential or commercial centere??
If you gain internal validity do you lose 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.
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.
What is Causal Validity?
Causal validity is also referred to as internal validity. It refers to how well experiments are done and what we can infer from those results.
Is it easier to increase internal validity than external validity?
No it is not easier because of the external flow.
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.
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.

Define internal validity?
Internal validity is higher when you stop confounding variables interfering with the experiment (things that effect the results). Internal validity occurs when a researcher controls all confounding variables and the only variable influencing the results of a study is the one being manipulated by the researcher. This means that the variable the researcher intended to study is indeed the one affecting the results and not something else.
What are the advantages and disadvantages of true experiments?
Advantages:Best design to establish causalitypower to detect effectsDisadvantagesInternal Validity issues - confoundsCannot examine some important social problems experimentallyExternal Validity issuesConstruct Validity issues - We do not know which part of the operational or conceptual IV had an effect on which part of the operational/conceptual DV
