    A Aggregating data from multiple sources to improve data quality. Correct Answer Incorrect Answer
    B Using historical data to identify patterns that help predict future events. Correct Answer Incorrect Answer
    C Dividing customer data into distinct segments based on behavior. Correct Answer Incorrect Answer
    D Creating real-time dashboards to monitor ongoing operations. Correct Answer Incorrect Answer
    E Developing data models that are only applicable to past events. Correct Answer Incorrect Answer

    Solution

    Trend analysis is essential in data analysis as it examines past data to uncover recurring patterns, making it possible to forecast future trends. Businesses apply trend analysis in various domains, such as sales forecasting, inventory management, and customer demand prediction. By understanding past behaviors, companies can adjust strategies and resource allocation to match anticipated trends, ensuring operational efficiency and market competitiveness. Option A is incorrect because aggregating data is part of data wrangling rather than trend analysis. Option C is incorrect as segmentation is aimed at dividing data into categories rather than analyzing historical patterns. Option D is incorrect since real-time monitoring is different from forecasting future trends. Option E is incorrect as trend analysis aims at future applicability, not just past evaluation.
