Why is important to graph data before analysis?

Graphing data before analysis is crucial because it provides a visual representation that can reveal trends, patterns, and outliers that may not be immediately apparent in raw data. Visualizations help in understanding the distribution and relationships within the data, guiding the choice of appropriate analytical methods. Additionally, graphs can simplify complex information, making it easier to communicate findings to others. Ultimately, this preliminary step enhances the overall analysis process and aids in making informed decisions.
