Answer: (C)

Using statistical analysis in scientific research serves the important function of summarizing data and identifying patterns. This involves collecting numerical data and applying statistical methods to interpret it effectively. By summarizing data, researchers can present their findings in a manageable form, allowing for easier understanding and communication of results. Additionally, statistical analysis helps in identifying trends, correlations, and relationships within the data, which can lead to more robust conclusions and insights. This process is fundamental to validating hypotheses, supporting experimental outcomes, and enhancing the reliability of research findings.
