Common Methods used in Case Study Research The goal of case study research is to understand the complexity of a case in the most complete way possible. On the other hand, quantitative research relies on random sampling; wherein a large representative sample is chosen in order to extrapolate the results to the whole population. Peshkin studies the culture of Bethany Baptist Academy by interviewing the students, parents, teachers, and members of the community, and spending eighteen months observing, to provide a comprehensive and in depth analysis of Christian schooling as an alternative to public education. Although, it generates ideas or hypothesis for later quantitative research. Following is a brief description of each type of quantitative research design, as well as chart comparing and contrasting the approaches.
Through this research now the bookstore owner can now keep books for different age categories and can improve his sales and customer outreach. Examples are provided of how these researchers' philosophical orientation influences the application of case study in practice. Qualitative and quantitative methodologies compared: Ontological and Epistemological Perspectives. Development of case study research in education, focused on the need to determine the impact of educational programs and provide relevant evidence for policy and practice decisions that supported social and educational change in the United Kingdom and the United States ibid. Quantitative research is most commonly conducted through large scale surveys with multiple choice or scaled rating questions.
When conducting survey research it is important that the people questioned are sampled at random. Many analytical tools exist such as independent sample t-tests, correlated t-tests, variance calculations, and regression analysis that can be used to derive results from the data. Causal-Comparative Research: This research method mainly depends on the factor of comparison. For example, diary accounts, , documents, , and ethnography. Results The finding of your study should be written objectively and in a succinct and precise format. By , updated 2017 There exists a fundamental distinction between two types of data: qualitative and quantitative.
Approach Qualitative Research is primarily subjective in approach as it seeks to understand human behavior and reasons that govern such behavior. There is a never-ending debate on, which research is better than the other, so in this article, we are going to shed light on the difference between qualitative and quantitative research. Correlational Research Correlational research tests for the relationships between two variables. Correlational research is conducted in order to explain a noticed occurrence. The aim of qualitative research is to understand the social reality of individuals, groups and cultures as nearly as possible as its participants feel it or live it.
The independent variable is established but not manipulated and its impact on the dependent variable is observed. Her research interests are in the areas of accessibility, innovation, relevance and quality in nursing education. They are: There are four different types of quantitative research methods: Primary quantitative research is the most widely used method of conducting. The data is then carefully collected from only those people who are most relevant to the objectives of the study. Existing data is summarized and collated to increase the overall effectiveness of research.
There are images also that are used in this research study and the researchers analyze the context in which the images are used and draw inferences from them. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon. Secondary quantitative research or desk research is a method that involves using already existing data or. Strengths Because of close researcher involvement, the researcher gains an insider's view of the field. Qualitative research and case study applications in education 2nd ed.
Key Features Research is used to test a theory and ultimately support or reject it. Conversely, in quantitative research measurable data is gathered. A prerequisite for this type of research is that the must have randomly selected members. In the past, teams relied exclusively on large, high-fidelity, and time consuming market research studies at the beginning of the product lifecycle. Statistics can be descriptive or inferential. Main Types of Qualitative Research Attempts to shed light on a phenomena by studying indepth a single case example of the phenomena.
Confirmation bias: The researcher might miss observing phenomena because of focus on theory or hypothesis testing rather than on the theory of hypothesis generation. Also, contexts, situations, events, conditions, and interactions cannot be replicated to any extent nor can generalizations be made to a wider context than the one studied with any confidence The time required for data collection, analysis and interpretation are lengthy. As the figure highlights, early case studies were conducted in the social sciences. The analysis of statistical data requires systematic tools and processes to be conducted. If appropriate, describe the specific instruments of analysis used to study each research objective, including mathematical techniques and the type of computer software used to manipulate the data.
Researchers can evaluate various variables at a particular time. Performing correlational research is done to establish what the affect of one on the other might be and how that affects the relationship. Surveys used to ask questions to a sample of respondents, using various types such as such as , online , paper , web-intercept surveys etc. Quantitative research method focuses on describing the characteristics of a population. Quantitative approaches are best when the need is to compare data systematically, such as a comparison between groups or countries. The family among the Australian Aborigines: A sociological study. If there are recording they should be transcribed and before the process of data analysis can begin.
