There are so many software packages available for solving design of experiments, forecasting simulation problems etc. SYSTAT, a software package offers mere scientific and technical graphing options than any other desktop statistics package. SYSTAT supports all types of scientific and technical research in various diversified fields as follows 1. Archeology: Evolution of skull dimensions 2. Epidemiology: Tuberculosis 3. Statistics: Theoretical distributions 4. Manufacturing: Quality improvement 7 5. Medical research: Clinical investigations. 6. Geology: Estimation of Uranium reserves from ground water 1.7 Limitations of statistics: Statistics with all its wide application in every sphere of human activity has its own limitations.
