Theory is defined as a scientific prediction or explanation for what the researcher expects to find. Theories can be used in quantitative, qualitative, or mixed methods research. In quantitative research, researchers often test theories as an explanation for answers to their questions. In qualitative research, the use of theory is much more varied. The inquirer may generate a theory as the final outcome of a study and place it at the end of a project or place it at the beginning and provide a lens to shape what is looked at and the questions asked. In mixed methods research, researchers may contain a theoretical framework within which both quantitative and qualitative data are collected (Creswell, 2014). What is the role of theory in research? Why is theory not used the same way for all research? Does it serve to connect components of the study? Is it a basis for selecting a research approach? Theory in quantitative research is the use of an interrelated set of constructs (or variables) formed into propositions, or hypotheses, that specify the relationship among variables (typically ...
In science, a theory will refer to an explanation of an important feature of the world supported by testing and facts that have been gathered over time. It’s there scientific theories that allow scientists to make predictions about untested and unobserved concurrences in the world. The American Association for the Advancement of Science has this explanation of what a theory means to those in the science field, and it is as follows, “A scientific theory is a well substantiated explanation of some aspect of the natural world, based on a body of facts......Such fact supported theories are not guesses but reliable accounts of the real
Theories are used as explanations of an experiment or study. A theory can be tested and then is used a predictor of something. People in criminal justice use criminological theories to explain why individuals commit crimes and based off of these theories, they can also see try to predict whether people will commit crimes and based off this try to prevent individuals from offending. In the criminal justice work field another set of theories are used called Management Theories. Similar to criminological theories, management theories can also help predict and explain people’s behavior. Management theories help explain behavior in the workplace. They are executed to aid in the expansion of employee output.
The theoretical framework in a research relates to the philosophical basis in which the research is executed. It also forms the link between the theoretical aspect of the research and the practical aspect of the investigation. Merten (1998) stated that it “has implications for every decision made in the research process” (p.3). Therefore, the starting point to any research proposal is to identify the methodologies (methods that can be used in the project and as well justify their choice (Crotty, 1998). The methodologies relate to “the strategy, plan of action, processes or design lying behind the choice and use of particular methods, and linking the choice and use of methods to the desired outcomes” (Crotty, 1998, p. 3).
There are many definitions to theory. According to Akers (2009) “theories are tentative answers to the commonly asked questions about events and behavior” (Akers, (2009, p. 1). Theory is a set of interconnect statements that explain how two or more things are related in two casual fashions, based upon a confirmed hypotheses and established multiple times by disconnected groups of researchers.
CONCEPT 2-NURSING THEORIES AND IMPORTANCE IN NURSING PRACTICE: Theory is an idea being argued with an intention to explain facts and is actually based on study. Theories are bodies of information and it interprets evidence by providing a new description that affects what is seen as relevant and what is not. Crucially, theories provide explanations of phenomena understood as an abstract.

A theory is basically a way to describe the essence of things. It involves careful consideration over what, how and why things come to be, how they work, and any interrelationship shared among other human realities. Theories seek to explain what the observer witnesses through thorough examination and thoughtful contemplation over matters some simple and some more complex (Akers, & Sellers, 2013). There is a distinct difference between ideas, thoughts and scientific theories and the essential component is what C. Wright Mills calls the sociological imagination (1959). It is important for intellectual thought to move from individual experience to a social standpoint, this shift the perspective from internal to external, becomi...
Theory: A general statement about some parts of the world that fit together and how they work; an explanation of how two or more facts are related
The father of quantitative analysis, Rene Descartes, thought that in order to know and understand something, you have to measure it (Kover, 2008). Quantitative research has two main types of sampling used, probabilistic and purposive. Probabilistic sampling is when there is equal chance of anyone within the studied population to be included. Purposive sampling is used when some benchmarks are used to replace the discrepancy among errors. The primary collection of data is from tests or standardized questionnaires, structured interviews, and closed-ended observational protocols. The secondary means for data collection includes official documents. In this study, the data is analyzed to test one or more expressed hypotheses. Descriptive and inferential analyses are the two types of data analysis used and advance from descriptive to inferential. The next step in the process is data interpretation, and the goal is to give meaning to the results in regards to the hypothesis the theory was derived from. Data interpretation techniques used are generalization, theory-driven, and interpretation of theory (Gelo, Braakmann, Benetka, 2008). The discussion should bring together findings and put them into context of the framework, guiding the study (Black, Gray, Airasain, Hector, Hopkins, Nenty, Ouyang, n.d.). The discussion should include an interpretation of the results; descriptions of themes, trends, and relationships; meanings of the results, and the limitations of the study. In the conclusion, one wants to end the study by providing a synopsis and final comments. It should include a summary of findings, recommendations, and future research (Black, Gray, Airasain, Hector, Hopkins, Nenty, Ouyang, n.d.). Deductive reasoning is used in studies...
On the other hand, Quantitative research refers to “variance theory” where quantity describes the research in terms of statistical relationships between different variables (Maxwell, 2013). Quantitative research answers the questions “how much” or “how many?” Quantitative research is an objective, deductive process and is used to quantify attitudes, opinions, behaviors, and other defined variables with generalized results from a larger sample population. Much more structured than qualitative research, quantitative data collection methods include various forms of surveys, personal interviews and telephone interviews, polls, and systematic observations. Methods can be considered “cookie cutter” with a predetermined starting point and a fixed sequence of
Quantitative investigation approaches attempt to exploit objectivity, replicability, and generalizability of answers, and are characteristically interested in forecast. Integral to this approach is the hope that an investigator will set aside his or her involvements, perceptions, and prejudices to ensure impartiality in the behavior of the study and the deductions that are drawn. Key topographies of many quantitative educations are the use of tools such as tests or reviews to collect data, and dependence on likelihood theory to test statistical premises that correspond to research queries of
Quantitative research involves the collection and converting of data into numerical form to enable statistical calculations be made and conclusions drawn. It provides a measure of how people think, feel or behave and uses the statistical analysis to determine the results. However, this measurement results in numbers, or data, being collected, which is then analyzed by using quantitative research methods (Byrne, 2007).
Traditional research may use quantitative or qualitative research method. According to Hendricks (2009), quantitative research is a general conclusion based on hard data. Hen-dricks describe quantitativ...
There are various approaches, which can be valuable for researchers to utilize when deciding an effective research problem. The failure of a researcher to be precise in the description of the problem statement can have damaging outcomes in the understanding of the research. A theoretical framework refers to a set of interrelated ideas or themes, such as a concept, but not fundamentally worked out. Determining on what comprises a theoretical framework of the study begins with recognizing and creating a good researchable problem.
The word theory emanated from the Greek word meaning “contemplate” It has been viewed by scholars in different ways. Theory can be defined literally as an explanation of phenomena and its associations with variables that it is attempting to predict. There are no general agreed definitions of theory because scholar’s views of what constitute theory differ based on the purpose, nature and what make up of a good theory (Gelso, 2006; Harlow, 2009; Stam, 2007, 2010; and Wacker 1998). For instance, Wacker, (1998), pointed out that a theory must have four basic criteria such as conceptual definitions, domain limitations, relationship-building, and predictions. He, also, opined that for any theory to be regarded as a good theory, it must have qualities for `good ' theory, such as “uniqueness, parsimony, conservation, generalizability, fecundity, internal consistency, empirical riskiness, and abstraction, which apply to all research methods” (p.364). Stam (2010) interpreted theory as ...
