Comparison Chart and Timelines

Comparison Chart

The process of creating a comparison chart can reveal similarities and differences among concepts, ideas, theories, perspectives and more.

A comparison chart can help you organize information by comparing and contrasting aspects of a topic.

A timeline organizes related information in chronological order. It can help you understand the sequence of unfamiliar events. Plotting events on a timeline or placing two timelines together can reveal patterns or themes that may be otherwise difficult to identify.


Timelines can be based on many kinds of information, for example biographical data, cultural periods, scientific discoveries, etc.
