When evaluating data, why is it better to make a graph instead of just looking at the raw data in a table?

A graph is usually better because it turns numbers into a visual pattern your brain can quickly interpret. Key reasons:

- Reveal trends and patterns fast — e.g., a time-series line shows an upward trend immediately; a table of numbers may hide it.
- Show relationships — a scatterplot makes correlations or clusters obvious; a table doesn’t show how two variables move together.
- Make distributions and variability visible — histograms or boxplots show spread, skewness and outliers at a glance.
- Highlight outliers and anomalies — points that don’t fit stand out visually.
- Simplify comparison — bars or multi-line plots let you compare groups or series quickly.
- Communicate results clearly — audiences understand visual summaries faster than columns of figures.

When a table is better: if you need exact values, small datasets with few points, or to look up specific numbers.

Tips for effective graphs: choose the right plot type, label axes and units, use an appropriate scale, include a legend, and avoid misleading choices (truncated axes, distorted aspect ratios).
