physical meaning of mean ?What is the physical meaning of mean value ? #2 20120916 15:20:09
Re: physical meaning of mean ?Mean can give you value around which the other values of the class are equally distributed. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?'

Re: physical meaning of mean ?It is a formula which can give you an approximation of the mean (as you're only using midpoints of class intervals for which presumably you don't know how the exact distribution of). As for a physical meaning, it has applications in mechanics too  you can apply a variation of that formula to find the centre of mass of a system.
