Ramya Professor, Department of Science and Humanities, RVS Technical Campus - Coimbatore, Coimbatore, Tamilnadu, India R. Radha A correlation coefficient is a statistical measure, which contributes measure, whichhe degree to which changes in one variable predict changes in another. In this article, we analyze the characteristics of Fermatean Quadripartitioned Neutrosophic sets with improved correlation coefficients. We have also used the same approach in multiple attribute decision-making methodologies including one with a Fermatean Quadripartitioned Neutrosophic environment. Finally, we implemented for above technique to the problem of multiple attribute group decision making. 2026 2026 01 07 10.54216/IJNS.270201 https://www.americaspg.com/articleinfo/21/show/3999
