Using statistical techniques to validate the hypothesis of independence in control charts

Abstract

The aim of this study was to identify and present the occurrence of autocorrelation in statistical data. To achieve this objective, a theoretical discussion was held on the subject and two exercises were also carried out using the R Statistical Software to show whether or not autocorrelation exists in statistical data. As a contribution of this research, a statistical technique using this software to show autocorrelation in data is pointed out.
