The same method of calculating K is used to calculate Q. Q, the reactant quotient, is different from K when the reaction has not reached equilibrium, and depending on how much larger of smaller Q is from K, one is able to tell whether the forward or backwards reaction is favored. Like what the person before said, Q=K when the reaction is at equilibrium. If Q<K at some point during the reaction (when Q is calculated), the forward reaction is favored. If Q>K at some point in the reaction, the reverse reaction is favored.
Q and K and calculated the same exact way: concentration of products over concentration of reactants. However, Q calculates the status of a reaction when it is not in equilibrium; the purpose is to understand what direction the reaction is currently moving in.
