Categorize

When you analyze information by categorizing, you create a system that helps you sort items into categories, or groups with shared characteristics, so that you can understand the information. Categorizing helps you see what groups of items have in common. What categories are shown on the chart below? Name at least one challenge you would list under each category. Then create your own chart following the steps below.

  1. Identify similarities and differences among items you need to understand. You need to pay careful attention and sometimes do research to find the similarities and differences among the facts, topics, or objects that you need to understand. Scientists find groups, or categories, of related animals by analyzing the details of the animals' bodies. For example, insects with similar wings, legs, and mouthparts probably belong in the same category. Gather similar information about all the things you need to understand. For example, if you know the location of one thing, try to find the locations of all the things you are studying. If you have different types of information about your topics, you will not be able to group them easily.
  2. Create a system to group items with common characteristics. Once you have gathered similar kinds of information on the items you need to understand, look for items that share characteristics or features. Create categories based on a feature shared by all of the facts, topics, or objects you need to understand. For example, if you have gathered information on the population and political systems of several countries, you could categorize them by the size of their population or their type of political system.
