How can spreadsheet and graph draw valid conclusions?

Spreadsheets can organize and analyze vast amounts of data through functions and formulas, allowing users to identify trends, patterns, and relationships. By visualizing this data through graphs, users can more easily interpret complex information, making it clearer to see correlations or anomalies. Together, spreadsheets and graphs facilitate informed decision-making by presenting data in a structured and accessible manner, enabling valid conclusions based on empirical evidence.
