Use of scientific methods Scientific methods refer to calculated research methodology that identifies a problem, provision of relevant data and a process of formulating the hypothesis based on experiments. The scientific method also involves systematic observation and testing of a specific hypothesis. Scientific methods constitute essential science experiments. The systematic methods are, used to determine naturally occurring phenomenon. This is a useful tool in explaining specific questions while maintain the area of focus.
Research problem refers to a topic or a subject which the researcher wishes to investigate, address and study through either experimentally or descriptively. This is the reason or the focus for the researcher to engage himself in research. Research Methodology therefore refers to a process which is adopted by the researcher to gather information and data for the purpose of addressing the research problem. The researcher should not only know what methods or techniques of research to use but must also be aware of which of these methods or techniques best suitable and relevant for his research and which are not. The researcher is expected to comprehend the assumptions underlying the different methods and also to know the criteria which will enable the researcher to decide that a particular technique or a procedure is applicable to his research methods.
Having decided on exactly what is to be studied the researcher then decides how the research can best be managed thus formulating a plan of action. Considerations include whether the research used should be primary or secondary. Whether one will test an existing hypothesis or whether one will construct a theory after having collated evidence. Finally one can draw conclusions as to which strategy to implement with the ultimate goal of producing the type of knowledge that is required. This then results in the type of method or methods of research to be used.
Maxwell’s research design has a definite structure. At the center of the design study, research questions should have a clear relationship to the goals or issues you want to address and why. Subsequently, the goals of the research should reflect previous knowledge, current theories and concepts and how they relate to the subject. However, if the research methods do not allow you to answer your research questions and/or validate them, your design will be
The whole idea can be based on the capacity to develop careful observation and draw tangible conclusion pinpointing variables, which might alter the results of research. Post positivism perspective is important to facilitate development on numeric measures aided by observation in studying behaviors of individuals. Post positivism outlines a guideline which should be followed whenever researching on any research topic (Welsh, 2007, p.173). The notion of Post positivism in relation to conducting a research involves outlining a theory, collecting data, which... ... middle of paper ... ...o present a holistic case study addressing the research question “why systems resist users.” Research methodology is based on both facts and theory. As noted, the world views are based on theories and beliefs.
The experimenter is interested in establishing causality through isolation of the causal effects and providing evidence. The independent variable is assumed to cause the change in the other variables and is therefore manipulated by the researcher. The dependent variable is influenced by one or more of the independent variables. Changes in the manipulated independent variable will consequently cause a change in the dependent variable. The function of an experimental design is to outline or plan a strategy used to answer the research question.
It is about the isolation of the dependent variable, whereby alternative explanations to the hypothesis are ruled out in the research design. This makes it impossible for observed changes in the dependent variable to be attributed to anything other than the independent variable (Bless et al. 2006, p. 93).

If the outcome of an experiment is not that in which was predicted, it is possible that the hypothesis is sound and the error lies in one or more of the auxiliaries. With this consideration, the logically decisive character of the crucial experiment is destroyed because of the uncertainty of exactly where the error lies. The outcome is supposed to support one Rafferty 2 2 hypothesis by completely falsifying its rival;... ... middle of paper ... ...ting that no hypothesis can be tested in isolation because of its background assumptions. The issue of recognizing whether error lies in one of the auxiliaries or within the entire theory is a problem that scientists will continue to face. I have argued that this problem casts doubt on the logic of falsification and the crucial experiment because the outcome of an experiment is not predicted on the basis of a single hypothesis since auxiliary assumptions are involved as well.
The scientific method follows a predictable pattern of asking questions, testing those questions, and then drawing conclusions from the tests that were conducted. Any research begins with a question, which is the basis of the scientific method. From there, research must be conducted to determine what testing has already been done in regards to the selected question. This helps scientists avoid repeating testing unnecessarily and can help direct their testing. Using the gathered information, the researchers can then construct a hypothesis.
Scientific research methods required experiments, they does not accept reasoning only but they demands a proper explanation based on facts, figures, observations and measurements. On the basis of methods research methods are divided into three groups in which some research methods are those that collects data and used at a place where already available data is not enough to carry out the solution about a problem. Some methods consist of such techniques that are used to develop a relationship between the collected data and unknown material. Similarly some other methods are used for evaluating and analyzing the accuracy of obtained results. Research methods are basically the analytical tools of research process.
