8. Quantitative Research "Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre- existing statistical data using computational techniques. Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to ...

Why should you take research methods? • This is a course on quantitative methods, not all research methods • Many of you will also take a qualitative methods module - PUBL0010, PUBL0085, or PUBL0058 • The science of the 'social sciences' comes from the methodological rigour of the approaches you will learn in these courses

Presentation Transcript. Quantitative Research Methodology Session 2 Variables, Population, and Sampling. Variable A characteristic that varies • Independent Variable "the factor that is measured, manipulated, or selected by the experimenter to determine its relationship with an observed phenomenon" (Tuckman, 1999, p.93) Variable (2) 2.

Quantitative research: is concerned with objectivity, tight controls over the research situation, and the ability to generalize findings. Qualitative research: is concerned with the subjective meaning of an experience to an individual. Concepts are abstractions of particular aspects of human behavior or characteristics (e.g., pain, weight).

This research paper offers a thorough examination of the benefits and drawbacks of applying quantitative methods to research in a range of academic fields. The precision, objectivity, and capacity to extrapolate results to larger populations are all provided by quantitative methods. They do, however, also bring with them certain difficulties ...

When collecting and analyzing data, quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings. Both are important for gaining different kinds of knowledge. Quantitative research. Quantitative research is expressed in numbers and graphs. It is used to test or confirm theories and assumptions.

Introduction to Quantitative Research. Elin Driana, Ph.D; 2 Research. a systematic attempt to provide answers to questions (Tuckman, 1999, p. 4) the more formal, systematic, and intensive process of carrying on a scientific method of analysis (Best and Kahn, 1986, p. 18). 3 Quantitative Research .

Aim of the study: The present study aimed to evaluate the effect of cognitive behavioral (CB) intervention on improving sleep quality in older adults. Design: A quasi-experimental pretest-and-posttest design was utilized to conduct this study. Setting: The study was conducted in the geriatric social club in Zagazig City.

In qualitative research, the: • Research reports tend to use flexible, emerging structure and evaluative criteria. • Researchers tend to take a subjective (reflexive) and biased approach. Quantitative and Qualitative Research • Both forms of research follow the six steps in the process of research.

This presentation will help you learn the significant differences between qualitative and quantitative research. You will understand what they are and when to use qualitative and quantitative research methods. You will get an idea about their research approach and the scientific methods used. Finally, we'll look at how to analyze data using these methods and see the final report. 1. What is it ...

Qualitative and Quantitative Paradigms • The qualitative paradigm concentrates on investigating subjective data, in particular, the perceptions of the people involved. The intention is to illuminate these perceptions and, thus, gain greater insight and knowledge. • The quantitative paradigm concentrates on what can be measured.

Quantitative research gathers data in numerical form which can be put into categories or measured in units of measurement. This type of data can be used to construct graphs and tables. Qualitative research gathers information that is not in numerical form. Qualitative data is typically descriptive data. When you think of qualitative data, Think ...
