The free statistical software links have the potential to be very useful to anyone involved in research and data analysis. The sites appear easy to navigate by choosing the statistic you need and plugging in the data. Some of the sites/links also have statistical definitions which would come in handy for anyone that needs a refresher course in statistics such as myself. My past experience with statistics have only been with using the SPSS software years ago. I guess you could say that I got away with not having to take a course dedicated only to statistics.
Now that I have some of these sites bookmarked they will be a good resource for any potential data analysis in the future.
