This girl wants to know how many students in her class walk to school and how many take the bus. Can she find the answer by looking on the Internet? Steps for Data Collecting It is best to create a plan before you begin collecting data. Following the three simple steps below will help to make sure you collect the data you need to answer your question properly.

Steps for collecting data: Pick a topic and come up with a question. Decide how you will gather your data. Choose the best way to organize and record your data so you can use it to answer your question.

Determining Your Question Data collecting begins with a question you want answered. Some questions can be answered simply with a yes or a no. Other questions have several possible answers.

The question you ask needs to be created carefully so that it will give you the answer or the information you need. Before creating your question, think about what you want to find out, and what kind of data you need to gather in order to answer your question. Would asking the question "What sports do you like?" give you the data you need if you were trying to find out who's favorite sport is hockey?
