Generally, what is the size of the bytecode stored in the EVM. I mean the approx average value of it or bytecode of a simple hello world program (setting and getting a string). On what factors this bytecode depends? and on how can i get this correct. i mean How can I know the correct value? is there any predefined keyword or command that gives this information.
Any relatable answer is appreciable !!

I'm not aware of anyone tracking these statistic, you will have to compute them yourself. Contract can vary a huge amount in size.
On what factors this bytecode depends?
It is more or less directly proportional to the length of your source code, although optimization runs can make the compiled size deviate from a purely linear relationship.

The eth_getCode function allows you retrieve the bytecode at a given address.
If you look at Ethereum's mainnet, as of late September (last time I processed contracts and addresses for stats):
I can't say for testnets, private nets (of course!) or other Ethereum forks.
