The research methods you use depend on the type of data you need to answer your research question. What Is a Quantitative Research Proposal? The two main types of quantitative data are discrete data and continuous data. 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. Simply put, quantitative research is all about numbers and figures. The researcher aims to precisely and define categories based on these facts before the study begins and then determines the relationships between them (Firestone, 1987; Smith, Bibb). For example, a ski hill that documents an assumption in a business plan that there will be at least 28 days of snow each season for the next 10 years based on climate predictions. The very most important purpose of the research is to widely explain the characteristics of a particular group or a bunch of . In some ways, the choice of quantitative approaches creates the reality we are attempting to discover. Measurement is the process of assigning numbers to the phenomenon using some type of rule (Burns & Grove, 1997). 0000000016 00000 n Quantitative Methods, Basic Assumptions The use of quantitative methods in political science generally means the ap-plication of a statistical model to political science data, and a statistical model is simply a set of compatible probabilistic assumptions. 0000010201 00000 n Based on the answers you get you can ask follow-up questions to clarify things. % C q" Quantitative data is data that can be counted or measured in numerical values. JFIF d d C However, for certain sensitive questions this assumption may be more difficult to accept, in which case it would be described as a limitation of the study. When the assumptions between the author and the reviewer diverge, the author's Sample selection depends on the population size, its homogeneity, the sample media and its cost of use, and the degree of precision required (Salant & Dillman, 1994, p. 54). endobj Nursing research: Generating and assessing evidence for nursing practice (9th ed.). The study can be replicated in different cultural locations, at different periods, and with different groups of people. Many more methodological features might be included in the methodology section, such as coding variables, missing value treatment, reliability and validity, and the tests to be employed. 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. Assumptions are things that are accepted as true, or at least plausible, by researchers and peers who will read your dissertation or thesis. 0000000843 00000 n 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.

This includes describing sampling processes, sample size, and data-gathering instruments such as questionnaires, interviews, observation, and technical measuring devices used in physical sciences. Data are considered factual or context-free when they have the same meaning across situations and settings (Hathaway, 1995). Thus unobservable realities exist and can be represented in theoretical concepts. It can be used to find patterns and averages, make predictions, test causal relationships, and generalize results to wider populations. 0000186222 00000 n 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). It is used to quantify opinions, attitudes, behaviors, and other defined variables with the goal to support or refute hypotheses about a specific phenomenon, and potentially contextualize the results from the study sample in . Books, publications, theses, journals, and other sources were utilized to create a research proposal example. The accuracy of a measurement is referred to as validity (whether the results really do represent what they are supposed to measure). 4.4.2 QUALITATIVE RESEARCH METHODOLOGY Health professionals view health care in adifferent manner than layperson.

Research using human objects has several ethical issues, such as maintaining the correspondents privacy, collecting data from them only with their consent, treating them with respect, and not forcing or harming them. This is commonly used for citing sources within the scope of your study. The The type of study design utilized in studies is not usually stated explicitly. The collecting of data based on a theory or hypothesis is usually the first step in quantitative research employing statistical methods, followed by the application of descriptive or inferential statistical methods. 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. 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. /SA true Table 2.2 Philosophical Assumptions With Implications for Practice The procedures of qualitative research, or its methodology, are characterized as inductive, emerging, and shaped by the researcher's experience in collecting and analyzing the data.
