The 41 has a [Σ+] key that dutifully sums up your data in half dozen registers somewhere, but what to do with it after that? Here's a whole kitchen cabinet of statistical support routines to help out, from the basics (means, deviations, correlations) to curve fitting, linear regression, ANOVAs and hypothesis testing. Scientists, social and physical: Don't leave home without your Stat Pac!
