Select Data: Android guide for choosing statistical tests
Select Data, by Diego Alejandro Pineda Poveda, is an Android app that guides students, researchers, and professionals through selecting appropriate statistical tests. The app uses interactive decision trees and variable classification to recommend parametric or non-parametric procedures based on research goals and data types. It packages definitions, step-by-step guidance for sample relationships, and educational modules on hypothesis testing and distributions. Designed for university students, thesis writers, and applied researchers needing portable methodological support.
What Select Data is and how it maps research choices
Select Data functions as a methodological assistant that evaluates variable types and research aims to suggest tests. The app provides interactive decision trees and classification tools for nominal, ordinal, interval, and ratio scales. Guidance follows the number of samples and the relationship between variables, so users follow a logical path rather than guessing which test fits their design. This framing targets decision-making, not numerical computation.
How the app supports learning and understanding statistics
Instructional material emphasises why a test is chosen rather than merely naming options. Educational modules cover hypothesis testing and data distribution analysis, and the app includes conceptual definitions to help beginners grasp terms. The decision-tree format offers step-by-step prompts, and core decision logic and definitions are typically available offline once installed, which helps self-paced study away from the desktop.
Who benefits and where it fits into research workflows
The app suits university students, thesis authors, and applied researchers in fields such as social sciences, health, and engineering who need methodological clarity during study design or fieldwork. The tool is specifically tailored to academic research workflows rather than general data entry, and its structured logic helps reduce common selection errors. Peer reception notes its utility for navigating statistics courses and thesis development.
Practical recommendation and key limitation
Select Data is a practical option for university students and researchers who want stepwise methodological guidance when choosing tests. Note that the app does not perform statistical calculations, so pair it with analysis software such as SPSS, R, or Excel for computation. Use the app during planning and method selection to reduce selection errors; it serves methodological clarity rather than replacing data-analysis tools.
