Listed below are the elements of a quantitative research proposal: A research proposal is a detailed outline of the research you intend to do. Statistical models in quantitative research designs are accompanied with assumptions as well, some more strict than others. Post-positivism allows researchers to examine realities through a variety of measurement tools; thus accessing realities which could elude measurement by direct observation (Giddings & Grant, 2007; Schumacher & Greener, 1992). The theoretical construct enables the researcher to design a research project on the subject of depression. It should contain a top page with bigger font size and capital letters for the study title, a middle page with submitted by and your name and contact information, and a bottom page with submitted to and the name of the professor, department, and institution to whom the document is submitted. The two main types of quantitative data are discrete data and continuous data. 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. . All research builds on philosophical and theoretical foundations. 0000006408 00000 n The author integrates design and analysis, and emphasises learning by example and critiquing published research. and Beck, C.T. 1. (2019, Dec 07). Any study in which all other variables except one are identified and controlled is considered a valid experiment.

Relationships between and among a multitude of facts are sought and understood in this style of design. 0000011099 00000 n In other words, there are facts with an objective reality separate from the beliefs of the researcher therefore reality exists regardless of the researchers presence (Firestone, 1987). 0000007050 00000 n 5 0 obj It works by offering a mathematical approach for determining when to buy or sell certain securities. Examples of delimitations include objectives, research questions, variables, theoretical objectives that you have adopted, and populations chosen as targets to study. What is the difference between the social behavior of college students and high school students? Quantitative research is the contrary of qualitative research, in which non-numerical data is collected and analyzed (e.g., text, video, or audio). 0 Based on the sampling method used, the results may be generalized to a larger population. 0000001817 00000 n Retrieved from https://paperap.com/paper-on-assumptions-in-quantitative-research/. << /Length 13 0 R /Type /XObject /Subtype /Image /Width 286 /Height 109 /Interpolate Philadelphia, PA: Lippincott, Williams & Wilkins., Corner, J. Outside of the physical sciences, statistics is the most extensively utilized field of mathematics in quantitative research, and it also has applications in the physical sciences, such as statistical mechanics. You might have avoided these options for reasons of practicality, interest, or relativity to the study at hand. This form of research will identify trends and patterns in data, but it will not go so far as to show causation for these observed patterns in its analysis. The two-sample t test is a type of inferential statistic used to determine if there is a significant difference between the means of two groups. w:xxN= ;)Z|7?Sz>xsw^ Xz>_L~T% ?`9s{%?

Quantitative and qualitative data can be collected using various methods. Quantitative approaches assume an objective approach to researching research problems, in which data is controlled and quantified, facts are accumulated, and causes of behavior are determined. (1991). Separating the universal from the particular is accomplished through several processes (e. G. , instrumentation and precision) and methodological assumptions (e. G. , measurement techniques) (Hathaway, 1995). Fundamen-tally, assumptions are modelling choices made by a researcher concerning the 2 0 obj There is also what we call a nursing research proposal in which serves as the cornerstone for a future nurse practitioners work. their teams to recalibrate old assumptions and models used to manage and monitor risk. The constancy of measurement is referred to as reliability (whether the results can be reproduced under the same conditions). 0000006171 00000 n Assumptions are things that are accepted as true, or at least plausible, by researchers and peers who will read your dissertation or thesis. 12 0 obj It consists of text, images or videos instead of numbers.

(2023, January 03). 0000187385 00000 n & Polit, D.F. For example, in most health care research, it would be ideal to conduct a qualitative study before design-ing a quantitative one as this would inform and im-prove the methodology of the latter.11 Yet, in most instances, this may not be possible due to limited time and other resources. If you want data specific to your purposes with control over how it is generated, collect primary data. Quantitative research is a method of learning about a specific group of people, referred to as a sample population. *@L}@"z,,D82X1Xp*0ddfX0#'Y@1gi ed_5];iKU?kdXMa#/{FGMt,,Y,,,@[54;8EX0a,&{ An extreme critique may be that reality is being actively structured by the researchers prosecuted categories and that this methodology is unduly controlled regarding what is relevant to the study. Additionally, there are assumptions that philosophies of childhood can be measured and done so objectively. Common quantitative methods includeexperiments, observations recorded as numbers, and surveys with closed-ended questions. Commonly accepted statistical devices should be noted, and unusual devices described. A quantitative study is referred to as a systematic approach meant to investigate a particular phenomenon [33], and the result is to derive a technique to rank an appropriate decision-making. 0000186012 00000 n Data collection is the systematic process by which observations or measurements are gathered in research. For example, Benmamoun and Lehnert (2013) included FDI, Remittances, ODA, openness, democracy, governance, inflation, population growth and initial GDP per capita. endobj 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). If the researcher thinks of quantitative design as a spectrum, the design at one extreme of the spectrum is one in which the variables are not controlled at all and are merely observed.

Pessimistic Assuming the worse possible outcomes. Journal of Nursing Scholarship, 33(2), 115-119., Polit, D. F., & Beck, C. T. (2012). An assumption is a belief that forms one of the bases for the research. Qualitative methods allow you to explore concepts and experiences in more detail. The assumptions of reality, objectivity and measurement are interrelated and integral to the ontology and methodology AT quant I t tattle research. Another Example of Assumptions In conducting this study the following assumptions were made. If you studied participants responses to a survey, you might be limited in your abilities to gain the exact type or geographic scope of participants you wanted. (eds.) w725C!GS3@>tZ,*m}$&Cw($\K(AWV . Regardless of whether the researcher adopts a positivist or post-positivist philosophy, the description of the paradigms begin with assumptions about the researchers role and relationship to the setting, and by identifying the epistemological and validity assumptions underlying the choice of the role and relationship. What Is a Quantitative Research Proposal? 0000002631 00000 n 0000001877 00000 n 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. %%EOF 9th ed.

Research projects can take many forms, such as qualitative or quantitative, descriptive, longitudinal, experimental, or correlational. In descriptive research, it is simply seeking an overall summary of the study. 0000175344 00000 n Taking a critical stance, Habeas (1971) claimed that such inquiry implies a dissociation of knowledge from human interest (Habeas, 2005) and questions the it with individual contexts, values, and preferences. A unique section addresses assessing the quality of mixed methods research and the challenge of reporting to help students evaluate the quality of their own studies as well as published studies. 0000002918 00000 n During the process of writing your thesis or dissertation, you might suddenly realize that your research has inherent flaws. The context of this data is usually rich and has depth to the information that has been given, so often can not be generalised to a wider population, nor can be transferred into statistics, unlike other methodologies such as quantitative data which uses a structured scientific approach towards collating data, in order to make the findings measurable and generalised to wider society. This method was originally developed in the natural sciences to study natural phenomena [Williams, 2007]. <<5B597C835E95614B9CD41072C1480025>]>> Quantitative data is data that can be counted or measured in numerical values.
