Stat-Lite provides an interactive and easy introduction to the concepts of Descriptive Statistics and Curve Plotting. It includes basic features like loading VOTable & ASCII format data set and performing some basic statistical analysis such as correlation tests, summary statistics etc. Some of the novel features of this application include graphs with multi-touch gesture support using which the user can pan and zoom to study specific areas, ability to study effect of outliers on regression fits by adding them using a simple interface etc. The interface & content has been designed for high-school & under graduate students. It uses 'Apache Commons Math' library for statistical calculations and a third party charting API called 'AChartEngine' for rendering graphs. As mentioned above, users can add or remove points by gestures like short and long press and see how the graph responds in real time The curve plotting module, apart from having all the major categories of pre-defined functions, has the ability to plot any arbitrary mathematical function by writing it down as a combination of the functions in the existing library. The prime motivation of this development was making useful software available on low-cost Aakash (Sky) Android tablets being made available to students in India.
