Hypotheses are also speculations of how variables in the study will work out,
and provide predicted answers to research questions. They embody the variables and
the population based on the problem statement (Clifford: 2000).

Purpose of Research Hypothesis

1. Hypotheses unify theory and reality by evaluating theory on the basis of
observable facts or reality.
2. Hypotheses give direction to research by determining research design, data
collection procedures, analysis and interpretation of data. Hypotheses also
determine the importance of data collected as explained by a known theory.
3. Hypotheses enhance knowledge by inducing critical thinking and deepening
insights. They help the researcher in the analysis and interpretation of findings
and in formulating conclusions. Findings and conclusions are answers to
specific research questions and the hypotheses raised in the study.

Types of Hypothesis

The hypothesis states the relationship between the independent and dependent
variables and the population to which relationship applies. It is simple, clear, and
concise and defines the variables in concrete and operational terms (Polit and Beck:
2004)

1. Simple vs. Complex Hypotheses
a) Simple Hypothesis. States an expected relationship between an
independent and a dependent variable, It is also called univariate
hypothesis.
b) Complex Hypotheses. Predicts the relationship between two or more
independent variables and two or more dependent variables; also called
multivarlate hypothesis because it involves multiple variables.

Supposing Hypotheses
X -is the single independent variable, the presumed Cause or
antecedent.
Y- is the single dependent variable which is affected or
influenced by one X Variable,
