An alternative hypothesis is a statement that suggests a potential outcome that the researcher may expect (H1 or HA). It states that the results are not due to chance and that they are significant in terms of supporting the theory being investigated. The alternative hypothesis states that there is a relationship between the two variables being studied (one variable has an effect on the other). Begin with the assumption that the null hypothesis is TRUE.States the assumption (numerical) to be tested.There might not be enough evidence against Ho. Not rejecting Ho does not really mean that Ho is true.The final conclusion of the investigator will either retain a null hypothesis or reject a null hypothesis in favor of an alternative hypothesis.
Ho states the opposite of what the experimenter would expect or predict.A null hypothesis also bears the features: It states results are due to chance and are not significant in terms of supporting the idea being investigated. The null hypothesis states that there is no relationship between the two variables being studied (one variable does not affect the other). The hypotheses can be expressed in the following ways: In research, there is a convention that the hypothesis is written in two forms, the null hypothesis, and the alternative hypothesis (called the experimental hypothesis when the method of investigation is an experiment). This usually involves proposing a possible relationship between two variables: the independent variable (what the researcher changes) and the dependent variable (what the research measures). Hypotheses are also important because they help an investigator locate information needed to resolve the research problem or sub-problems (Leedy and Ormrod, 2001)Ī hypothesis (plural hypotheses) is a precise, testable statement of what the researchers predict will be the outcome of the study. The hypothesis helps an investigator to collect the right kinds of data needed for the investigation. An investigator may refer to the hypothesis to direct his or her thought process toward the solution of the research problem or sub-problems. It provides a tentative explanation for a phenomenon under investigation (Leedy and Ormrod, 2001).Ī hypothesis is important because it guides the research.
A hypothesis is a logical supposition, a reasonable guess, and an educated conjecture.A hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation.Hypotheses are relational propositions.Hypothesis relates theory to observation and observation to theory.A hypothesis is a conjectural statement of the relation between two or more variables (Kerlinger, 1956).Ī hypothesis is a formal statement that presents the expected relationship between an independent and dependent variable.A hypothesis may be precisely defined as a tentative proposition suggested as a solution to a problem or as an explanation of some phenomenon (Ary, Jacobs, and Razavieh, 1984).
