What is the most used statistical analysis software between SAS and SPSS? ?

Your question is not clear madam. Are u asking for statistical analyses that can perform on sas or spss? or u r asking which of this 2 software has more statistical function or more powerful? l am using both of this software l found sas more powerful in terms of completeness of statistical anlyses & a more detailed outputs. But the spss is more user friendly & does not require programming abilities. l mean u can make analysis directly without typing the correct program for ur query/analysis. You can find & use on both software the ''most used'' analyses in statistics like Descriptive Stats, ANOVA, T-test, Correlation, Regression, Time Series & Forecasting, Multivariate Analysis, Non-parametric tests, Survival analysis, etc.. But if u r a beginner, l advise u to use the spss..
