  3. 3.  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?
  4. 4.  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
  5. 5.  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
