Generate data from previous values

[RaulCosta]

First, I apologise for my english skills, as I am not a native speaker.

This may be a super newbie question, but I couldn't find similar topics in this forum. I am making a view to input data from a survey wich is consisted primarly by questions like "In the last 3 months, how many times did you...", options from 0 to 6, focusing workers health. It's based in a risk and illness inventory and from these numbers, I need the mean and median of values from each questionnaire.

Is there a way to have that automatically generated and inserted just after I typed the items values?

Tu queres a média e mediana para cada paciente ou de todos os pacientes que participam do estudo?
