- Data acquisition is crucial in research because:
- Validating Theories: It provides evidence to support or refute theoretical frameworks.
- Measuring Outcomes: It enables researchers to quantify results and draw meaningful conclusions.
- Evidence-Based Practices: It forms the foundation for making informed and effective decisions.
- Therefore, the correct answer is B: It helps in validating theories and measuring outcomes, as it highlights the role of data in confirming hypotheses and supporting empirical research.

- Data acquisition is crucial for evidence-based practices because it provides the raw material for analysis and interpretation.
- Collecting accurate and comprehensive data allows researchers and practitioners to make informed decisions based on empirical evidence.
- Good data acquisition supports the development of reliable conclusions, enhances the validity of research findings, and guides effective decision-making.
- It is foundational for identifying patterns, verifying hypotheses, and implementing effective interventions across various fields.
