A hypothesis is a statement of the relationships between factors or causes and the problem or phenomenon under study.  

A hypothesis is a statement of the relationships between factors or causes and the problem or phenomenon under study. You as a researcher can identify a problem or phenomenon, find the main causes or effects of the problem, and provide the possible solutions to the problem. For example, if you study the problem of divorce and try to find the main causes of divorce, you may hypothesize that lack of communication is more likely to cause divorce. In this case, lack of communication is one of the main causes of divorce.  Also remember that a hypothesis should be direct, specific, and measurable. For example, if you study gender inequality or women as minority group, you try to argue that women are subordinated and discriminated against. You can hypothesize that women are more likely to earn less income than men do. Income here is measurable and is an indicator to measure discrimination against women. You can examine discrimination against women in aspects of income, power, occupation, education, etc. The following hypotheses might help for brain storm purpose. Your sources that you have collected also will assist you.
