This paper presents the information on the characteristics of a good research hypothesis. This is because theories are broad in nature and they explain larger bodies of data. Well, this bad mood is not justified, the physicist who has just abandoned one of its assumptions should be, on the contrary, full of joy, because he has found an unexpected opportunity for discovery. Therefore, testability is one of the important characteristics of scientific research. At each step, you need to be clear about every aspect and dimension. The controlled factors or variables should have to be controlled rigorously.
Scientists must consider the variables that are going to be manipulated in the experiment and be sure to include them in the hypothesis itself. In an experiment, the researcher systematically manipulates a variable of interest known as the independent variable and measures the effect on another variable known as the dependent variable. Journal of Experimental Social Psychology, 2, 160-168. Hypothesis can be one and it can be as many as possible. Before the inductive generalization, usually a hypothesis is framed.
The question for this post is excellent! Hypotheses are often but not always derived from theories. Scientists then use a large battery of to arrive at a hypothesis that is , and realistic. Watch for words like ought, should, bad. These variables are often stated in , in a , e. It is not the only use of hypothesis. Some hypothesis can not be tested because they are too subjective and they are not suitable for research.
That is to say that if changes in one variable actually cause another to change. The concepts embodied in the hypothesis must have clear empirical correspondence and should be explicitly defined. Descriptive studies can also be conducted without a hypothesis. Thus the two theories made opposite predictions so that only one of the predictions could be confirmed. Thirdly, adoption of positivism in business studies and other studies can be criticized for reliance on status quo.
It guides the direction of the study: Quite frequently one comes across a situation when the researcher tries to collect all possible information on which he could lay his hands on. When you know that your hypothesis only deals with a particular aspect of the phenomenon you will not collect data that is not required and the objectivity and validity of the research increases. Objectivity: Every research requires objectivity but without hypothesis you may collect data which is not relevant to the research and hence decreases the objectivity of the research. These methods are best used to describe different aspects of a behavior or psychological phenomenon. Research hypothesis can be present in research and it may not be but if it is present it can have following benefits. In this way very often hypothesis is framed to explain a law. A good hypothesis is a statement that helps to explain the occurrence of a specified group of observable phenomena.
When similar event is tested in research, due to the broader nature of factors that effect that event, some factors are taken as controlled factors while others are tested for a possible effect. Stebbins expresses it as 'a hypothesis is a proposition suggested by the evidence available to establish the conclusion but insufficient to demonstrate the conclusion'. Whether it is approved or not it gives you some conclusion and adds to the available body of knowledge. Moreover, positivism relates to the viewpoint that researcher needs to concentrate on facts, whereas phenomenology concentrates on the meaning and has provision for human interest. Hypothesis formulation helps in formulating the research problem.
Rejection of the null hypothesis leads to the acceptance of the alternative hypothesis. Often the researchers are tempted to express their hypotheses in terms so general and so grandiose in scope that they are simply not amenable to test. For obvious ethical reasons, researchers cannot create a situation in which a person behaves aggressively toward others. So a hypothesis is often a prediction based on a theory but some hypotheses are a-theoretical and only after a set of observations have been made, is a theory developed. The aim of hypothesis is to reach at the real explanation and to remove the puzzlement concerning the event.
Modern logicians prefer the term ' explanation' in place of 'hypothesis'. If you are using second-hand information in your research due to any reason your research might complete in less time but its credibility will be at stake because secondary data has been manipulated by human beings and is therefore not very valid to use in research. Differences between Positivism and Interpretivism The key features of positivism and social constructionism philosophical approaches are presented in the following table by Ramanathan 2008. Descriptive hypotheses typically state the existence, size, form, or distribution of some variable. The role of researcher when following the scientific approach is to discover specific nature of cause and effect relationships. The first is to raise a research question, answer that question by conducting a new study, and then offer one or more theories usually more to explain or interpret the results. It does not believe on air castles but it is based on observation.
