External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events. Internal validity is concerned with threats or factors other than the independent variable that affect the dependent variable. 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.

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.

Internal validity is the extent to which a piece of evidence supports a claim about cause and effect, within the context of a particular study.

The language of internal and external validity is not used by everyone, but many of us would agree that intuitively the distinction makes a lot of sense. Two claims are commonly made with respect to intern-al and external validity. The first is that internal validity is prior to external validity since there is nothing to gener-

the balance technique would allow for more generalizability than would the eliminate or hold constant techniques In contrast, internal validity is the validity of conclusions drawn within the context of a particular study.

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.
