Statistical charts are visual representations of data that help people understand complex information quickly and easily. They can take various forms, such as bar charts, line graphs, and pie charts, each serving a different purpose. For example, a bar chart can compare quantities across different categories, while a line graph shows trends over time. These charts are widely used in fields like business, education, and science to present findings clearly. By transforming numbers into visuals, statistical charts make it easier for audiences to grasp key insights and make informed decisions based on the data presented.
