PS. UML now has equivalent diagrams, used for conceptual modelling (look for UML Domain Models, that show [domain] entities as classes with just a name).

Quality Control: Statistical packages (Comparison)

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

Comparison of statistical packages - Wikipedia

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.

RESOURCE: On Software Development Methodologies

The non-exaustive-use-with-care list of resources on software development methodologies includes some additional information on the waterfall - agile/scrum "recipes" - some of which include variants and/or predecessors of it:

• https://en.wikipedia.org/wiki/Software_development_process - several methodologies listed including FDD, TDD, etc.
• https://en.wikipedia.org/wiki/Software_development_process#Spiral_development - focus on iterative deliveries and risk management as well as planning as explicit parts of the methodology
• https://en.wikipedia.org/wiki/Extreme_programming - unit testing, pair programming, involve the end-customer, stand-up meetings
