DataStat - data analysis and statistics with 3D plot free app for iPhone and iPad

*** 3D scatter plot, advanced regression analysis, the most powerful data analysis App ***

It is all about Data. In this data-driven environment, no matter you are a marketing manager, a HR manager, or a lab scientist, you need to be able to make decisions and draw conclusions based on data. You need a handy tool to collect, process, and manipulate data.

It is about Statistics. To explore and analyze the data you collect, you need a powerful tool to interpret them. You need a statistics tool that can help you to discover scientific relationship among the data, or to build a useful business model to guide the strategy of an organization.

It is about DataStat, the most powerful data analysis App so far for iPad. It offers a full range of data analysis and statistics features. From simple and very useful features like normal distribution (z-test) table lookup, to advanced regression analysis with 3D scatter plot. It can handle xls/xlsx/csv files directly, and thus greatly simplifies the process of collating and manipulating data. It offers much more features than the popular DataAnalysis App.

For students, DataStat can help you to better understand the statistics concept. For teachers, DataStat can change your iPad into a powerful tool to demonstrate the course material.
