The importance of the control charts of statistical software in the control of abnormalities. The objective of this work is to use statistical techniques in software to identify, correct and eliminate abnormalities present in education science problems. These characteristics enable the CEP to assist in the monitoring of the process and allows actions to be taken in a way directed to solve problems, assisting in the stabilization of the process and avoiding the production of non-compliant items (HORA and COSTA, 2009 MAYER, 2004). Therefore, the reduction of abnormality in families of variables is of paramount importance in the statistical process.Īccording to Souza and Rigão (2005), the CEP acts preventively on the process using statistics as a base element to evaluate its changes. In “Any production process, regardless of how well designed or maintained it is, will always be subject to a natural or inherent variability, which is the result of the cumulative effect of many small and inevitable causes, called common causes” (MONTGOMERY, 2004, p.154). Information and new technologies have established a globalized environment of high competition, in which price and deadline should be met (VILAÇA and OLIVEIRA, 2011). Institutions are concerned with maintaining high performance indices with regard to quality and productivity due to the requirements in the provision of services. The use of statistical software is an important tool for studies and applicability in the control of variations in probability and statistical problems. From information it is possible to study statistical problems related to the control of variability applied in the sciences in engineering, chemistry, physics, mathematics, geography and etc. Statistical methods refer to data obtained from observations in the form of measurements or counting. Its purpose is to obtain, organize, analyze data, calculate control charts, correlations and regressions, enabling control in variability, statistical applications and educational institutions. Statistics is a branch of mathematics that uses the probability tool to explain data groupings, both in observational studies and in experiments to model, estimate and predict future phenomena. Keywords: Probability, Minitab Software, Control Chart. Therefore, it is concluded that the tool from corrective actions is able to stabilize the standard deviations and improve the quality of probability and statistical applications. The results obtained allowed to reduce losses and improve the quality process through sample adjustments between minitab control limits, providing to understand and analyze the causes of anomalies. In the realization of this theme, the quantitative methodology and the control chart of the Minitab Software were used. Thus, we sought to study concepts about control charts by variables and attributes in the control of abnormalities. The present study mentions the reduction of variability and losses due to special causes in applications of the educational sciences, aiming to detect and correct variability deviations through software control charts in applied statistical problems. ![]() ![]() ISSN: 2448-0959, Access link: educational-science ABSTRACT Revista Científica Multidisciplinar Núcleo do Conhecimento. ![]() Probability, control chart applied to educational science software.
