The document defines a hypothesis as a tentative generalization that requires empirical testing. It discusses different types of hypotheses including those that affirm characteristics, associate variables, or establish causal relationships. Hypotheses can originate from general culture, scientific theories, analogies, or personal experience. For a hypothesis to be workable, it should be specific, conceptually clear, testable with available techniques, relate to existing theory, simple, and capable of empirical testing. Formulating hypotheses provides a point of inquiry, direction for research, and allows selection of relevant facts and conclusions. The document also introduces the null hypothesis as a negative formulation of the actual research hypothesis.
