Data comes in two basic forms: Numerical – numbers Textual – words Data comes from many sources Let’s brainstorm a few… First open a program called Inspiration Now name some sources
Sources include: Existing statistical sites online ▪ Real time data sites Repositories of events like encyclopedias and books Our own experiments Surveys and questionnaires All around us in all kinds of forms ▪ Text ▪ Visuals
What is difference between your memory and a computer when it comes to managing data? ▪ How many e-mail contacts can you recall from your address book? ▪ If you read long speech, how long does it take you to determine the key themes? ▪ If you take notes from a lecture, how do you determine the most important information?
Spreadsheet programs like Microsoft Excel Keep track of numerical data Allows you to sort or filter data Allows you create formulas to answer questions Allows you to display and communicate data visually through charts and graphs Also has a way to grab real-time data (search Google for “Real time data sites”) Online sites such as Many-Eyes, Google Earth or Google Public Data let you visually represent numerical data in powerful ways
Inspiration and Kidspiration let you link text Draws out connections Visually shows the important data Add images to enhance understanding Many-Eyes and Wordle are online tools to help express text data visually for analysis Wikis are also a way to capture text data in the form of an encyclopedic form
Develop a lesson/activity relevant to your discipline, topic, and grade level that involves data analysis using one of the tools.
