Randomization is a fundamental technique used to eliminate bias and ensure that experimental results are due to the intervention rather than external factors. It is crucial in research design, particularly in randomized controlled trials, to achieve reliable and valid results by evenly distributing unknown confounding variables across treatment groups.

External factors are influences that originate outside an individual or organization, affecting decision-making, performance, and strategy. These factors can include economic conditions, social trends, regulatory changes, and technological advancements, all of which require careful analysis and adaptation to maintain competitive advantage.

Research design is a structured framework that guides the collection, measurement, and analysis of data in a study, ensuring the validity and reliability of results. It encompasses the choice of methodology, data collection techniques, and analysis procedures to effectively address the research question or hypothesis.

research design

Randomized Controlled Trials (RCTs) are the gold standard in clinical research for determining the efficacy of interventions by randomly assigning participants to either the treatment group or the control group. This design minimizes bias and ensures that any observed effects can be attributed to the intervention itself rather than external factors.
