Role of Computer Technology in Statistics

With the advancement in computer technology, many innovative techniques for use in applied statistics have recently been developed. In most of the disciplines like medicines, agriculture, business and government these application have solved important problem. Performing calculations almost at the speed of light. The computer has become one of the most useful research tools in modern times. Computers are ideally suited for data analysis concerning large research projects. The computer can perform many statistical calculations easily and quickly. Computation of means, standard deviation, correlation coefficients, t-test, analysis of variance(ANOVA), analysis of covariance(ANCOVA), multiple regression, factor analysis and various non-parametric analysis are just few of the programs and subprograms that can be solved easily using computer. Similarly, using computer, linear programming, multivariate analysis, Moute Carlo simulations etc. also can be done very easily. Software packages are available for the various simple and complicated analytic and quantitative techniques of which researchers generally make use of. The only work, he researchers has to do is to feed the data he/she gathered after loading the operating system and particular software package on the computer.

SPSS,SAS,STATA etc. are the special statistical packaged program where Microsoft Excel can also be used for simple statistical analysis.
