Case: Once the variables relevant to the topic of research have been identified, then the researcher is interested in the relationship among them.
•A statement containing the variable is called a proposition. It may contain one or more than one variable.
•The proposition having one variable in it may be called as univariate  proposition,  those with two  variables as bivariate  proposition, and then of course  multivariate containing  three or more variables.
•Prior to the formulation of a proposition the researcher has to develop strong  logical arguments  which could help  in establishing the  relationship.
•For example, age at marriage and education are the two variables that could lead to a proposition: the higher the education, the higher the age at marriage .  What could be the logic to reach this conclusion? All relationships have to be explained with strong logical arguments. If the relationship refers to an observable  reality, then the proposition can be put to test, and any testable proposition is hypothesis.
