In this part of TimeWeb we look at number crunching and all that is involved in the processing and analysis of data. We investigate the following themes:

• Processing - making sense of data
• Analysing - how to handle time series data
• Relating - making connections between data items
• Experimenting - testing for significance

The best way to navigate around the section is to use the navigation bar on the left-hand side of the page. Each of the above themes has a variety of resources to help you understand the issues. The resources include:

• Explanation - a brief explanation of the issues relating to that theme
• Illustration - some examples of using the techniques covered under the theme
• Worksheets - a series of interactive worksheets looking at how the techniques can be applied in practice
• Review - a brief summary of the issues covered under the theme

The best way to start off using this section may be to have a look at the tour for 'crunching' which gives an overview of the resources available and what they cover.
