What's the difference between stochastic and random? What's the difference between stochastic and random?
A variable is random. A process is stochastic. Apart from this difference, the two words are synonyms.
There is absolutely a difference between stochastic process and randomness. For example, if I take one step then let's suppose my friend takes two steps. Now my friend's steps are not random, those are dependent on my steps. That means my friend's steps has a process which is the number of steps I take. But it is random because my friend doesn't know how many steps I will take. So the steps I take is a random walk.
