How are internal and external validity related?

As the researcher attempts to control for internal validity, external validity is usually decreased. The researcher must decide how to balance internal and external validity. More test answers on https://studyhippo.com/ch9-307/

9.14 The “experimenter’s dilemma” refers to the trade-off between: 1) experimental and correlational research 2) between-subjects and within-subjects designs 3) internal and external validity 4) treatment and error variance 5) experimental and control groups

Define both internal and external validity

From a research perspective, the more representative a sample is, the better able we are to generalize to the larger group. The extent to which we can generalize our findings beyond the study itself is called external validity; internal validity reflects how confident we can be in the results of a particular given study More test answers on https://studyhippo.com/abnormal-psychology-study-guide-1/

Contrast internal and external validity

Internal validity= free of contamination by extraneous influences is a matter of degree; findings may have high or low internal validity Ex.- the effect of class size on cheating have low internal validity due to the possibly confounding effect of exam format very important; without it, a study cannot provide clear, interpretable results. External validity= extent to which causal relationships in a research setting/population can be generalized outside of the study in the real world. Important & desirable because the results of a study often have general importance only if they generalize beyond the particular setting in which they appeared.

What is Internal And External Validity?

Internal validity and external validity are two important concepts used in research to determine the accuracy of data or results. Internal validity refers to the extent to which results or findings accurately reflect what was actually studied, while external validity refers to the extent to which results can be generalized from one study or setting to another. A study with high levels of internal and external validity is considered reliable and accurate.Internal validity involves ensuring that all measures taken during a study accurately capture the phenomenon being studied, including using valid instruments, avoiding confounding variables, and having adequate sample sizes. To ensure internal validity, researchers must use reliable methods of data collection, careful design of experiments and control groups and accurate measurements. In addition, researchers should also consider potential sources of bias such as demand characteristics or experimenter effects. By doing so, they can increase their chances that the results found are an accurate reflection of what was studied rather than some other factor influencing the outcome. External validity refers to how well a study’s findings can be generalized across other settings or populations. External factors include characteristics such as representative samples (e.g., gender, race) within a study population; this means that if a certain pattern is found in a particular group then it could potentially be replicated in similar groups elsewhere too. Additionally, external factors include replicability (i.e., ability for someone else to repeat your research) as well as transferability (i.e., ability for your findings to be applied outside of their original context). Ultimately, researchers should make sure that any conclusions drawn from their studies can be generalizable beyond its specific context so that others may benefit from them too by being able to apply them elsewhere successfully. In conclusion, both internal and external validity are essential components for conducting successful research as they ensure accuracy in measurement as well as generalizability across different contexts respectively.
