It is a formula which can give you an approximation of the mean (as you're only using mid-points 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.

Mean can give you value around which the other values of the class are equally distributed.
You can know, what you are choosing is neither more nor less

What is the physical meaning of mean value ?
using this formula .
mean = (f * m) / n
where f is the frequency of each class and m is the mid point of each class
n is sum of frequecy
What is the physical meaning of mean using above formula ?
