Can We identify the Research Hypothesis with the Alternative Hypothesis?

Abstract

The research hypothesis is commonly a statement of the relationship between concepts and is derived from a theory or stored knowledge in a certain research field. The statistical hypothesis, on the other hand, is the expression of a parameter that characterizes population distribution, so it does not contain any logical reasons for specific relationships or characteristics within it (Hay 1981, p. 232). In general, the statistical hypothesis is derived from the research hypothesis, but not vice versa.
