What is meant by standardization in research?

Standardization in research refers to implementing uniform procedures for all participants involved in a study. This approach ensures that every participant is subjected to the same conditions, instructions, and equipment usage, which minimizes the potential for variability that could influence the results. By maintaining consistency across all aspects of the study, researchers can confidently attribute differences in outcomes or responses to the manipulation of the independent variable rather than to variations in how the research was conducted.

This uniformity is crucial for enhancing the reliability and validity of the research findings. When all participants experience the same procedures, it allows for better comparisons and ensures that the data collected can be interpreted meaningfully, reducing bias and confounding variables. In contrast, varied procedures or adaptations based on participant feedback could introduce inconsistencies that compromise the integrity of the research results. Randomizing procedures may help distribute potential confounding variables but does not ensure the same level of uniformity required for true standardization.
