One excellent sum-up of the most widely used statistical packages (think SPSS, Minitab, JMP):

You could be asking what does statistics (and stats software packages) have to do with software development? Well, a lot, mainly if you're interested in improving (and predicting) the things you do.
Knowing the "numbers" from the past (Process Performance Baselines, PPB) and predicting the future with models built using these baselines (Process Performance Models - PPM) are very powerful tools to management (estimation, detecting deviations from normal process behaviour, etc.).
"Quality Control" areas also have a great deal of statistics (needed to compute Descriptive Statistics as well as creating and maintaining those PPB and PPMs).
So, in fact statistics basics given in High School really do apply to some Software Engineers and Software Quality Assurance (or Software Product Assurance) Engineers.
