Lab 22: Data Mining and JavaScript

• On your own, find five real world examples of data mining.
• Selecting one of those examples, describe the data, the method for data mining, and the result.
• Put together a quick html file (or use an old one). Add a script tag that prints out the date the document was last modified. (Most of Chris' lecture and lab slides have that code.)
• Modify the html file so that it has a form with two text boxes and a button.
• Now make a javascript function that stores the value of those boxes.
• Now modify the button tag to catch the onClick event. When you catch the event, call that javascript function that stores the value.
• Now, modify the function (and use a global array) to store multiple pairs of numbers.
• Finally, calculate the average of the pairs when a second button is pushed.
