Abstract
The existing F -test of linearity cannot be applied when data has indeterminacy and uncertainty. The present paper introduces the F -test of testing linearity under neutrosophic statistics. We will develop F -test under neutrosophic statistics and neutrosophic analysis of the variance (NANOVA) table. The application of the proposed test will be given using the data of dry bulb temperature and relative humidity. From the analysis and comparison studies, it is found that the proposed F -test under neutrosophic statistics gives the results in indeterminate intervals and measures of indeterminacy. In addition, the proposed test is more flexible, adequate, and more informative than the F -test under classical statistics.
