RE: Mean and standard deviation on the HP25

Even if number entry is in progress, the stack is pushed and either mean or sdev is placed in the X register. I always assumed, that the reason why Σy² is not calculated, is the only 8 registers available, and using Σ+ within a program would only leave two registers for general use. But also the fully used 2k program memory could be the reason for only calculating x mean. Bernhard That's one small step for a man - one giant leap for mankind. |
