| ## The basics of being a data scientist | |
| * Have a hypothesis - even if you're making a tool/api that helps people with their questions too, remember what the objective of that is. | |
| * Find the people and tools you need to prove/show/find. This rest of this page will help with the latter. | |
| * Analyse and present results - were they what you expected? Do they help explain to others what you have found out? Can present as a interactive data visualisation or a web/mobile application or just a infographic/motion graphics video that tells a story. | |
| Please note, there are a combination of Analysis and Visualisation tools in each of the major categories below. | |

| Illustration from Data Journalism Handbook, CC BY-SA 3.0</dd> | |
| The best high level reference is the 'Understanding Data' and 'Delivering Data' chapters of the Data Journalism Handbook which is available online for free at | |
| [datajournalismhandbook.org](http://datajournalismhandbook.org/) | |
| You can learn the technical skills from scratch in Visualize This: The FlowingData Guide to Design, Visualization, and Statistics by Nathan Yau or for more advanced | |
| practical advice check out Data Analysis with Open Source Tools by Philipp K. Janert | |

| **Statistics** | |
| [http://greenteapress.com/thinkstats/html/index.html](http://greenteapress.com/thinkstats/html/index.html) | |
| **Programming** | |
| Programming is valuable skill for manipulating and displaying data. | |
| Basic tutorials for a variety of languages are available for free online or you can learn | |
| interactively with websites like [http://www.codecademy.com/](http://www.codecademy.com/#!/exercises/0). for JavaScript or [http://www.learnpython.org/ ](http://www.learnpython.org/)or [http://tryruby.org](http://tryruby.org/) | |
| [https://developer.mozilla.org/en/JavaScript](https://developer.mozilla.org/en/JavaScript) - especially for web applications and visualisations, you'll need a basic understanding of JS. Common libraries like prototype or jQuery can help | |
| **Accessibility/User Experience** | |
| WCAG guidelines not only make a web app accessible but make it a better experience for all users! Even if not making an app, good to consider these things to do and not do: [http://www.w3.org/TR/WCAG/](http://www.w3.org/TR/WCAG/) | |
