DIG Stats is an excellent Web site for teaching middle and high school students the fundamentals of statistics. By incorporating real life data sets and challenging "data visualization activities," students can learn how to assess significant statistics and then represent them graphically. The three main areas of the site are descriptive statistics, inferential statistics, and graphical analysis. Several topics are introduced in each of these areas, and students can start by reading the background material. They then apply what they have learned to the activities, which utilize Microsoft Excel or the TI-83 graphing calculator. Step-by-step instructions are given on how to use these tools.
