Explanation

The question defines the core principle of random sampling, which is a type of randomization.
Randomization ensures that every subject in the population has an equal and independent chance of being selected.
This method is considered the gold standard for creating a representative sample because it minimizes selection bias.
By giving everyone an equal chance, the sample is more likely to mirror the characteristics of the entire population, which allows the findings to be generalized.

Option A: Control refers to the group in an experiment that does not receive the intervention. It is used as a baseline for comparison, not a method for selecting subjects.
Option C: Manipulation is the action of the researcher changing the independent variable (the intervention) to see its effect. It does not relate to how subjects are selected.
Option D: A variable is a measurable characteristic or attribute that can change or differ among subjects (e.g., age, weight, blood pressure). It is what researchers measure, not the process of selection.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Principles of Research Sampling as background academic context rather than a clinical decision trigger.
Understanding research terms like randomization is crucial for nurses to practice evidence-based care. It allows them to critically appraise research articles and determine if the findings are valid and applicable to their patients.
Nurses often participate in or conduct research. Knowing the correct methodology for sampling ensures the quality and integrity of the research.
What if? - If a researcher did not use randomization and instead chose participants they thought would respond best to a new treatment (a form of selection bias), the treatment might appear more effective than it actually is. This would lead to incorrect conclusions and potentially harmful clinical practice changes.

How to Approach the Question

First, read the question carefully to identify the key concept. The question is asking for the term that describes a specific process: 'every...subject has an equal chance to be selected'.
This is a definition-based question. Your goal is to match the definition in the stem to one of the terms in the options.
Analyze each option. Think about the definition of 'Control', 'Randomization', 'Manipulation', and 'Variable' in the context of research.
Eliminate the options that clearly do not match. 'Control' is a group, 'Manipulation' is an action, and 'Variable' is a characteristic. None of these describe a selection process.
The term 'Randomization' directly relates to the concept of giving an equal chance, making it the correct fit for the definition provided in the question.
