Reality affects human beings and unman beings effect reality (Schumacher & Greener, 1992). The conviction that there is a reality existing outside of the researcher, hat this reality can be observed (ontology), and that knowledge of this reality can be measured objectively (epistemology) are foundational assumptions in quantitative research (Hathaway, 1995). Statistical models in quantitative research designs are accompanied with assumptions as well, some more strict than others. Revised on Survey Research. In other words, it is essential that the measurement tool(s) and process are objective to gain closer proximity to true knowledge of the phenomenon. Then, to answer your study questions, you can apply statistical analysis.

G. , telescope), the data is examined and analyzed to determine if logical patterns are present, and rational theories are constructed to explain and predict a variety of facts (Hathaway, 1995). The term bibliography refers to sources that are used solely for the purpose of obtaining information but are not used for any other purpose. St. Louis, MO: Saunders Elsevier., Monti, E., & Tingen, M. (1999). In any case, you should clearly list the other options available and the reasons why you did not choose these options immediately after you list your delimitations. For example, in surveys, observational studies or case studies, your data can be represented as numbers (e.g., using rating scales or counting frequencies) or as words (e.g., with open-ended questions or descriptions of what you observe). This method was originally developed in the natural sciences to study natural phenomena [Williams, 2007].

It aids in reflecting on the fundamental component of the chosen issue considering the literature provided. Conclusion 9 References 10 Assumptions Underlying Quantitative Research Introduction Before researchers undertake a research endeavor, it is essential for them to understand the philosophical assumptions that underlie the method of inquiry chosen to answer the proposed research question. There are various approaches to qualitative data analysis, but they all share five steps in common: The specifics of each step depend on the focus of the analysis. Control is inherent in this method of inquiry which is another underlying assumption of quantitative research. For example, if you tell your friend that your favorite restaurant is an Italian place, your friend will assume that you dont go there for the sushi. startxref And it's just becoming more vital as more, Lights, camera, but not so fast on the action. Simply put, quantitative research is all about numbers and figures. This allows the respondent to talk in some depth, choosing their own words. Beliefs about the variables Predictions about the relationship of two. Only the relationships between variables are described. The effects of identified control groups exposed to the treatment variable are compared to those who are not. Therefore quantitative data does not bring out the feelings and opinions of the, Polit, D. F., & Beck, C. T. (2012). %%EOF Examples of delimitations include objectives, research questions, variables, theoretical objectives that you have adopted, and populations chosen as targets to study. Published on This is commonly used for citing sources within the scope of your study. The most rigorous form of quantitative research follows from a test of a theory (see Chapter 3) and the specification of research questions or hypotheses that are included in the theory. You may only mention the principal style intended for analysis in your study proposals, such as how the data will be displayed in graphs, charts, tables, and diagrams to be studied. What is quantitative research and how to measure it. 0000141513 00000 n Nursing research: Methods and critical appraisal for evidence-based practice (7th ed.). It presents your research topic and reflects what you aim to investigate and how you propose to investigate it. 6 0 obj If you were researching whether there are different parenting styles between unmarried Asian, Caucasian, African American, and Hispanic women, then a delimitation of your study would be the inclusion of only participants with those demographics and the exclusion of participants from other demographics such as men, married women, and all other ethnicities of single women (inclusion and exclusion criteria). However, no adequate evidence exists to support this belief. quantitative research, unlike in the qualitative paradigm where he/she is regarded as a great research instrument due to his/her active participation in the research process, is considered as being external to the actual research, and results are expected to be replicable, no matter who conducts the research. The goal is to persuade the reader that the subject is worth investigating. Read the references, on the other hand.

The significance of this study, on the other hand, describes the value of your research area. The genuine experiment is frequently mistaken for laboratory research, although this is not always the case; the laboratory setting has no bearing on the true experiment. You may overlook other significant observations if you use predetermined variables and measurement methodologies. While it is impossible to achieve complete objectivity, cultivating an awareness of potential threats and taking measures to decrease threats whenever possible serves to strengthen the research project. Quantitative and qualitative data can be collected using various methods. Quantitative research is the process of collecting and analyzing numerical data.

These assumptions generally refer to the characteristics of the data, such as distributions, correlational trends, and variable type, just to name a few. For instance, if you state that generalizability is a limitation of your study given that your sample was limited to one city in the United States, then you should not claim generalizability to the United States population as an assumption of your study. Measurement is an important assumption in quantitative research and measurement tools, if properly designed and applied, can lead the researcher to greater understanding about the phenomenon. w !1AQaq"2B #3Rbr Some examples of this type of research questions include: What are the differences between attitudes to social media trends of millenials and middle-aged adults? endstream endobj 13 0 obj<> endobj 14 0 obj<> endobj 15 0 obj<>/Font<>/ProcSet[/PDF/Text]/ExtGState<>>> endobj 16 0 obj<> endobj 17 0 obj<> endobj 18 0 obj<> endobj 19 0 obj[/ICCBased 29 0 R] endobj 20 0 obj<> endobj 21 0 obj<> endobj 22 0 obj<> endobj 23 0 obj<>stream % /Subtype /Image Which type you choose depends on, among other things, whether youre taking an inductive vs. deductive research approach; your research question(s); whether youre doing experimental, correlational, or descriptive research; and practical considerations such as time, money, availability of data, and access to respondents.
