Introduction to the Free Statistical Package - R for Social Work Research and Evaluation
Statistical packages such as SAS, SPSS, and Stata are expensive. Thus, many social work agencies have to use Excel statistical toolpak for data analysis. Although Excel statistical toolpak is free, it has numerous limitations.
