What are the threats to the validity of a contemplated piece of research, and what means are available to neutralize these threats?
Understand the Problem
The question is focused on understanding the validity of research and the means to maintain it through various control strategies. The discussion highlights the key issues of potential threats to research validity and methods to neutralize these threats, including random assignment, instrumentation, and statistical control, among others.
Answer
Threats include history, maturation, selection bias, etc. Counter with randomization, control groups, and consistent techniques.
Threats to research validity include history, maturation, selection bias, instrumentation, testing effects, regression to the mean, social interaction and others. To neutralize these threats, researchers can use strategies such as randomization, control groups, blinding, and ensuring consistent measurement techniques.

Threats to research validity include history, maturation, selection bias, instrumentation, testing effects, regression to the mean, social interaction and others. To neutralize these threats, researchers can use strategies such as randomization, control groups, blinding, and ensuring consistent measurement techniques.
More Information
Internal validity threats are concerned with whether the study actually shows what it claims. Using control groups and blinding can help improve the internal validity. External validity threats focus on the generalizability of the results. Adequate sampling methods help in improving external validity.
Tips
Common mistakes include inadequate randomization and neglecting to use control groups. These can lead to biased results that do not accurately reflect the true relationships or effects being studied.
