Statistical Data analysis is used to answer research questions. It involves many steps and techniques; steps may involve data gathering, cleaning, and transformation; techniques may involve simple procedure such as descriptive analysis to complex procedure such as regression analysis and model building. On these pages, you will find useful information that will assist you in the analysis of your data.

 

Which Statistical Software to Use?

Which software you use depends on what you are doing. For instance if you are interested in generating some summary statistics like mean, median, frequency, etc. then all three of them (SPSS, SAS & Minitab) are good. If you are interested in Time Series analysis then SAS is recommended. The default graphics from Minitab are better than that from SAS or SPSS. If you want to design an experiment or carry out prospective power and sample size calculation Minitab or SAS are the best. If you want to generate an interactive pivot table then SAS and SPSS are the best. Of the three software SAS is heavily used in industry compared to SPSS or Minitab.  These are just some quick but non exhaustive guides to help you select the most appropriate statistical software depending on what you want.
