Association and Causation Statistics is the science pertaining to the collection and analysis of data. It is the refinement of the ambiguous‚ the distilling of truth from the crudest of resources. For this reason‚ it is necessary to discern the simplest path from Point A to Point B‚ disregarding any unnecessary data that may lie in the path. This‚ however‚ is easier in theory than in practice‚ and statisticians have developed various techniques to help differentiate between causation‚ a variable directly

And the measure of correlation called as correlation coefficient or correlation index summarizes in one figure the direction and degree of correlation.
