Hypothesis - correct answersa tentative explanation to a question about variables , their
relationships, and other facts involved in the research.
1. They guide you on which aspect of the research to focus on.
2 They provide opportunities to prove the relationship between variables.
3. They give the right direction of the research.
4.They outline your thoughts on your manner of summarizing the results and of explaining the
conclusions.
5. They push for an empirical study to prove the existence of relationship - correct
answersPurposes of Hypotheses
null hypotheses, alternative hypotheses - correct answerscategories of hypotheses
, null hypothesis - correct answerssymbolized by Ho, which states the absence of relationship
between the independent and dependent variables.
alternative hypothesis - correct answersSymbolized by Hi, states the relationship between the
independent and the dependent variables and the fact that the first affects the second one
Theory-driven vs. Data-driven hypotheses, Directional (one-tailed) vs. Non-directional (two-
tailed) hypotheses, Descriptive vs. Causal hypotheses - correct answerstypes of hypotheses
Theory-Driven Hypothesis - correct answersA hypothesis that is based on existing theory to
explain the relationship of variables and the effects of one variable on the other variables
Data-driven hypothesis - correct answershypothesis based on the findings of previous research
studies
Directional (one-tailed) hypothesis - correct answersstate the relationship of two variables as
well as of the
relationship of these variables.
Non-directional (two-tailed) hypotheses - correct answersstate the relationship of variables but
not on the direction of the relationship.
Descriptive Hypothesis - correct answersA statement specifying the relationship between two
variables due to the influence of something
Causal Hypothesis - correct answersHypothesis due to cause and effect relationship, used by
experimental researches
Review of Related Literature - correct answersThe systematic identification, location, and
analysis of documents containing information related to a research problem.
