## Graphing Data Sets

How Do You Decide What Type of Graph to use for a Data Set? Visualization of numeric data is an important concept of statistics, a major branch of mathematics. Kids must have a clear understanding of the differences between a line graph, a pie chart, and a bar graph.
When you know the difference between all these graphs and charts, you will know exactly which type to use for a specific data set.
**Line Graph** - To represent data with small differences, a line graph is an appropriate choice. It is specifically used for tracking changes over a short or a long period.
**Pie Chart** - It is a useful data visualization tool that helps in comparison or parts of a whole. Pie charts cannot be used for tracking changes over time.
**Bar Graph** - Bar graphs are a great choice for data sets, which involves changes in data over time. As a line graph is a useful tool to visualize small changes, a bar graph is a right choice for data involving larger changes over a period of time.
