Hypotheses identify different types of relationships and numbers of variables. A well-formulated hypothesis clearly identifies the relationship between the variables. A hypothesis's value is ultimately derived from whether it can be tested in the real world. A testable hypothesis is one that contains variables that can be measured or manipulated in the world.
