Day-to-day life relies on hopes, projections and assumptions. Without being willing to consider improvement or plan action, company can't advance. In any field of operation, the educated usage of data is of direct interest. In carrying out preparation, designing, gathering evidence, evaluating, drawing concrete analysis and documenting the study results, statistical methods are involved. The mathematical analysis brings significance to the statistics that are irrelevant, thereby breathing life into lifeless results. Only if proper mathematical analysis/tests are used are the findings and inferences precise. The purpose of this paper was to provide a summary of the significance of statistics and statistical instruments in science.
