External and Internal Validity ! Internal Validity – the degree to which the results are attributable to the independent variable and not some other rival explanation ! External Validity – the extent to which the results of a study can be generalized 7

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 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 is an important property of any study. There are two types of study validity: internal (more applicable with experimental research) and external. This section covers external validity. External validity involves the extent to which the results of a study can be generalized (applied) beyond the sample. 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).

Why internal validity is not prior to external validity Johannes Persson & Annika Wallin Lund University, Sweden Corresponding author: johannes.persson@fil.lu.se [Abstract: We show that the common claim that internal validity should be understood as prior to external validity has, at least, three epistemologically problematic aspects: 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). External validity can be improved by setting experiments in a more natural setting and using random sampling to select participants.

Internal validity examines whether the study design, conduct, and analysis answer the research questions without bias. External validity examines whether the study findings can be generalized to other contexts. External validity (sometimes called ecological validity) is concerned with the extent to which the results can be generalized to groups and settings beyond those of the experiment. In other words, external validity focuses on threats or rival explanations that would not permit the results of the study to be generalized to other settings.

Internal validity refers to the construction of the study and means that conclusions are warranted, extraneous variables are controlled, alternative explanations are eliminated, and accurate research methods were used. 2020-08-11 · 8.3 External validity. External validity is often considered in terms of the relevance of the study; how transferable is it to the context of the question? As noted above, some studies can be of high internal validity (low risk of bias) but may be misleading on account of low external validity (low relevance).

predictive validity the effectiveness of one set of test or research results as a predictor of the outcome of future experiments or tests. 3.6 External and internal validity. All studies should be designed to be externally valid (Chap. 5) and internally valid (Chaps. 7 and 8) as far as possible.. A study is externally valid if the results are likely to be generalise to other groups in the population, apart from those studied in the sample.

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.
