Abstract
In this paper we present the development of a modulated web based statistical system, hereafter MWStat, which shifts the statistical paradigm of analyzing data into a real time structure. The MWStat system is useful for both online storage data and questionnaires analysis, as well as to provide real time disposal of results from analysis related to several statistical methodologies in a customizable fashion. Overall, it can be seem as a useful technical solution that can be applied to a large range of statistical applications, which needs of a scheme of devolution of real time results, accessible to anyone with internet access. We display here the step-by-step instructions for implementing the system. The structure is accessible, built with an easily interpretable language and it can be strategically applied to online statistical applications. We rely on the relationship of several free languages, namely, PHP, R, MySQL database and an Apache HTTP server, and on the use of software tools such as phpMyAdmin. We expose three didactical examples of the MWStat system on institutional evaluation, statistical quality control and multivariate analysis. The methodology is also illustrated in a real example on institutional evaluation.
Highlights
For decades the pattern of rationality based on statistical analysis has experienced slowness, which begins with the data collection, passes by the statistical analysis itself, and ends up in the final presentation of the results obtained in form of a report

Summary
For decades the pattern of rationality based on statistical analysis has experienced slowness, which begins with the data collection, passes by the statistical analysis itself, and ends up in the final presentation of the results obtained in form of a report. In the present paper we built the MWStat system environment which is based on a scheme of devolution of real time results, accessible to anyone with internet access In other words, these procedures are focused on how to build a user-friendly interface and how to relate any website with the R software to generate dynamic results for any online purposes. We used the phpMyAdmin interface (http//:www.phpmyadmin.net) as an auxiliary tool, related to the administration of MySQL database using PHP language These technologies were gathered in a LAMP server (Linux, Apache, MySQL and PHP), which is a popular solution of free open source software to build a viable web server of general purpose with a low costing structure and high performance (Neiderauer, 2004).
