Type in one or more words, separated by commas. Google Trends will display line graphs showing the number of searches on those words over the past five months, along with other interesting graphs and statistics.

For example, type: math|maths, coffee (the vertical bar acts like "or"). The data and graphs show that overall more people are searching for maths than for coffee. But not in Washington DC.

Lots of good fun and good maths to be had here.

This applet teaches students in a very dramatic way how changing the "bin width" of a histogram can dramatically alter the shape of the histogram. Lesson: you should graph your data with a number of different bin widths and choose the one that you feel best represents the data.

A clever web page for constructing a bar graph on the fly. All the necessary elements are editable - scales, axis labels, title, etc.

The Stroop Test is a fun and engaging way to collect numerical data for later analysis and display. From the flipchart: "In the Stroop Test, the participants are given a list of words, and are asked to say the colour of the word, and not the word itself ... Most people take longer to say the colour of the word when the colour of the word doesn't match the word itself."

The Baby Name Wizard is a fascinating website that graphically displays the number of babies with different names over the years. You can easily track the popularity of different names. What do you think was the most common boy's name and most common girl's name in 1990?

Note that the website takes some time to appear as it has to download a lot of data. Be patient!
