This type of internal validity could be assessed by comparing questionnaire responses with objective measures of the states or events to which they refer; for example comparing the self-reported amount of cigarette smoking with some objective measure such as cotinine levels in breath.

External validity is the validity of applying the conclusions of a scientific study outside the context of that study. In other words, it is the extent to which the results of a study can be generalized to and across other situations, people, stimuli, and times. In contrast, internal validity is the validity of conclusions drawn within the context of a particular study. Because general conclusions are almost always a goal in research, external validity …

External criticism is a process by which historians determine whether a source is authentic by checking the validity of the source. Internal criticism looks at the reliability of an authenticated source after it has been subjected to extern

Since internal validity is based on a cause and effect relationship between specified variables, if that is what the researcher seeks to identify, then there is a strong case for establishing internal validity (Cozby 2014). Although at face value, external and internal validity are literally opposite of each other, they both are working synergistically for the social relevance of your research. Examples of Research Validity. Check out several internal and external validity examples in the following downloadable PDF files. 1. Internal validity can be improved by controlling extraneous variables, using standardized instructions, counter balancing, and eliminating demand characteristics and investigator effects. External validity refers to the extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical validity).

In other words, internal validity focuses on threats or rival explanations that influence the outcomes of an experimental study but are not part of the independent variable. Table 13.1 Threats to Internal Validity Internal validity is the most important requirement, which must be present in an experiment, External Validity Applicability of evaluation results to other populations, setting and time periods is often a question to be answered once internal validity threats have been eliminated or minimized. Below is a selection of external threats that can help guide your conclusions on the generalizability of your research results: The key difference between internal and external validity is that internal validity is the extent to which the researcher is able to make the claim that no other variables except the one he is studying caused the result whereas external validity is the extent to which results of a study can be generalized to the world at large. internal validity) we are making the experiment more and more artificial and thereby it’s generalizability (external validity) suffers. An exception would be in reference to specific control techniques e.g. the balance technique would allow for more generalizability than would the eliminate or hold constant techniques This type of internal validity could be assessed by comparing questionnaire responses with objective measures of the states or events to which they refer; for example comparing the self-reported amount of cigarette smoking with some objective measure such as cotinine levels in breath. External validity The concept of validity is also applied to research studies and their findings.

Internal validity is very difficult to achieve in the non-laboratory setting of the behavioral experiment in which there are so many extraneous variables to attempt to control. Internal validity only shows that you have evidence to suggest that a program or study had some effect on the observations and results. Construct validity determines whether the program measured the intended attribute. Internal validity says nothing about whether the results were what you expected, or whether generalization is possible.
