FacExp: Desenvolvimento de uma aplicação para apoiar o planejamento, execução e interpretação de experimentos fatoriais

Abstract

This work presents the development of a factorial analysis tool herein named FacExp, a modern web application designed to support the planning, execution, and interpretation of factorial experiments, an essential statistical technique in scientific research and industrial applications. The proposal arises from the scarcity of accessible, intuitive, and integrated tools that allow for the complete conduct of this type of experiment, especially for users without an advanced statistical background. The system was built based on agile software development methodologies, prioritizing usability, modularity, scalability, and portability. The solution stands out by consolidating, into a single platform, functionalities ranging from experimental design to statistical analysis and graphical visualization of results, all within a 100% textitonline environment. To demonstrate the tool’s feasibility and correctness, a functional validation was performed through a practical use case. In this scenario, a full factorial experiment was simulated, demonstrating the system’s capability to correctly perform ANOVA calculations and generate relevant graphical visualizations. Thus, FacExp effectively contributes to democratizing the use of experimental statistics, supporting the scientific process, and expanding the use of robust statistical methods in a simple and interactive manner.
