When are methods aimed at minimizing bias determined in the context of a research study?

Methods aimed at minimizing bias are determined prior to the study because this planning is critical to ensuring the integrity and validity of the research findings. By establishing strategies for reducing bias in advance, researchers can create a sound methodological framework that guides how the study will be conducted. This includes selecting appropriate study designs, sample sizes, randomization techniques, and blinding procedures, all of which are essential to controlling for factors that might skew the results.

Addressing bias in the planning stage allows researchers to anticipate and mitigate potential confounding variables that could affect the outcomes. It is essential that these considerations are made before any data collection begins to ensure that the research remains objective, reproducible, and credible throughout the entire process.

The other options reflect aspects of the research process but do not appropriately address when bias reduction strategies should be formulated, as data collection, result analysis, and conclusions occur after the study design is established.
