Introduction

Statistical science has experienced rapid growth in recent decades, mainly thanks to the spread of computers and their ability to perform complex calculations quickly and accurately. In the past, even the calculation of a simple mean required time and persistent effort, while procedures such as matrix inversion were considered time-consuming and difficult. With the arrival of computers, statistics and informatics advanced hand in hand, giving new impetus to both theory and practice. It is characteristic that some of the very first computational systems were designed to facilitate the processing of large volumes of statistical data, such as population censuses.

Historical Overview

The development of computers led to the creation of the first statistical packages, that is, specialized software designed to facilitate data analysis. These early packages were usually oriented toward specific techniques, such as tabulations or hypothesis testing, and required specialized programming knowledge. Gradually, however, advances in technology resulted in more user-friendly packages, with graphical interfaces and tools that allowed even non-specialists to perform complex analyses. One of the earliest and most well-known statistical packages was BMDP, which has been in use since the late 1950s and remains a point of reference for its historical value. Its long presence in the field highlights the important role it played in the development of the discipline, as does the programming language FORTRAN, which served as a tool for the development of many such packages.

Catalogue of Statistical Packages and Tools

Today, there is a wide range of statistical packages and tools that cover different analytical needs. From specialized software for multilevel modeling to general packages for quality control, the variety is immense. In the market, we find software such as AcaStat, MedCalc, XLSTAT, StatView, Stata, NCSS, SigmaXL, among many others. Most of these provide features for statistical analysis, modeling, forecasting, time-series analysis and graphical data representation. The vast availability of software allows scientists, researchers, businesses and students alike to choose the package that best fits their needs and their level of expertise.

Notable Statistical Packages

According to international evaluations, some of the most popular and widely used statistical packages include IBM SPSS Statistics, which is broadly used in both research and business fields thanks to its user-friendly environment and wide range of tools; RStudio, a powerful open-source platform for data analysis supporting both R and Python; EViews, which is highly valued for its econometric and forecasting capabilities; Stata, extensively used in academic research for its rich statistical tools and high-quality graphics; and JMP, known for its interactive and visual orientation, which helps reveal hidden patterns in data. Also significant is OriginPro, tailored to the needs of physical sciences and engineering with strong signal analysis and statistical fitting capabilities, while TIMi Suite provides a modern environment for big data analytics and artificial intelligence. Furthermore, Minitab is widely used in industry and education for quality control, Scilab is a free open-source software for numerical computations, and Grapher specializes in the creation of high-quality scientific graphs.

Conclusions and Remarks

The development of statistical packages has greatly boosted scientific research, education and business analysis. Today, their use is indispensable, even for small-scale samples, as the required calculations would be difficult to perform otherwise. However, their ease of use also carries a serious risk: the misuse or uncritical application of statistics. Running a process in a statistical package does not by itself guarantee reliable results. The computer simply executes the algorithms it is given, but the choice of method, the understanding of assumptions and the interpretation of results belong to the researcher. For this reason, a solid knowledge of statistical theory remains a prerequisite for their proper use. The correct application of methods and awareness of their limits are of vital importance in order to draw conclusions that hold scientific value and practical significance. Therefore, statistical packages are irreplaceable tools, but it is responsible and critical use that determines the quality and reliability of the outcomes.
