Quasi-experimental study: Quasi-experimental studies are similar to experimental studies, but participants are not randomly assigned to groups. A procedure adopted on the chance of its succeeding, for testing a hypothesis etc., or to demonstrate a known fact. The essence of Newton's theory of gravitation is that the force between two bodies is proportional to the product of their masses and the inverse square of their separation and that the force depends on nothing else. A _________ variable is a variable that is related to the explanatory variable, and it also affects the response variable, making it difficult to determine which one of the two is really causing the response.
