What Is A Hypothesis? Comparative Politics Hypothesis Exercise (Essay Sample)
WHAT IS A HYPOTHESIS?
A hypothesis is a preliminary or tentative explanation or postulate by the researcher of what the researcher considers the outcome of an investigation will be. It is an informed/educated guess.
It indicates the expectations of the researcher regarding certain variables. It is the most specific way in which an answer to a problem can be stated.
It is a statement: I) postulating a possible relationship between two or more phenomena or variables; and 2) describing a phenomenon or which specifies a relationship between two or more phenomena.
DIFFERENCE BETWEEN A HYPOTHESIS AND A PROBLEM
Both a hypothesis and a problem contribute to the body of knowledge which supports or refutes an existing theory. A hypothesis differs from a problem. A problem is formulated in the form of a question; it serves as the basis or origin from which a hypothesis is derived. A hypothesis is a suggested solution to a problem. A problem (or question) cannot be directly tested, whereas a hypothesis can be tested and verified.
WHEN IS A HYPOTHESIS FORMULATED? -
A hypothesis is formulated after the problem has been stated and a review of the scholarly literature study has been concluded. It is formulated when the researcher is aware of the theoretical and empirical background to the problem.
PURPOSE AND FUNCTION OF A HYPOTHESIS
• It offers explanations for the relationships between those variables that can be
• It furnishes proof that the researcher has sufficient background knowledge to enable
him/her to offer suggestions in order to extend existing knowledge.
• It gives direction to an investigation.
• It structures the next phase in the investigation and therefore furnishes continuity to the
examination of the problem.
CHARACTERISTICS OF A HYPOTHESIS
• It should have elucidating power.
• It should strive to furnish an acceptable explanation of the phenomenon.
• It must be verifiable; i.e. it can be proven to be correct.
• It must be formulated in simple, understandable terms.

Thinking Critically and Doing Comparative Politics
Hypothesis: Affordable Care Act 2010 has led to coverage expansion which has subsequently caused a decline in the number of uninsured Americans, improved access for the insured populations, increased revenue and demand for healthcare, and subsequent enhancement in healthcare outcomes.
RATIONALE OF HYPOTHESIS CHOICE
This hypothesis will be tested to determine the impact of insurance coverage expansion as a result of Affordable Care Act 2010 on the number of uninsured Americans. A decline in the number of uninsured will be an indicator of a positive effect of coverage expansion, while an increase or no change in the number of uninsured would indicate that ACA has had no impact on the uninsured populations. It's expected that healthcare coverage expansion under ACA would lead to a substantial decline in the number of uninsured Americans as compared to the pre-ACA era where structurally, Americans were covered under Medicare and Medicaid. The outcome of this hypothesis test will reflect whether or not ACA has the potential to bring about universal coverage as earlier envisaged.
Secondly, this hypothesis will be tested to determine if indeed there exists an association between coverage expansion under ACA and change in demand for healthcare in the United States. If it is determined that coverage expansion has led to increase in demand for healthcare across sampled healthcare facilities, then it would be concluded that indeed, ACA has the potential to bring about universal coverage. However if coverage expansion does not spark increase in healthcare demand, especially among the uninsured Americans, then the research would conclude that it would be impossible to attain universal coverage under ACA 2010.
Thirdly, the hypothesis will be tested to determine if there exists a relationship between coverage expansion under ACA and a change in hospital revenue. If coverage expansion has sparked an increase in hospital revenue, then the research can conclude that universal coverage can indeed be attained under ACA. However, if it turns out that it has led to a decline in hospital revenue, the research can conclude that it would be impossible to attain universal coverage as the ACA healthcare model is unsustainable. This is because sustainability of the healthcare model is critical towards attainment and sustenance of universal healthcare. If coverage expansion leads to an increase in hospital revenue and a decl
