CORE: Quantitative Research Methodology: An Overview
6 likes567 views
The document is an overview of quantitative research methodology presented by Dr. Carlos Cardillo, focusing on defining and differentiating quantitative and qualitative research methods. It emphasizes the importance of choosing the right research design based on research questions and variables, outlining various types of quantitative research designs such as descriptive, correlational, quasi-experimental, and experimental. The presentation also highlights the relevance of statistical analysis in quantitative research while contrasting it with qualitative methods.
CORE: Quantitative Research Methodology: An Overview

- 3. 3 We can classify research methods in two main categories: Quan>ta>ve and Qualita>ve This webinar will provide an overview of quan>ta>ve methods with a brief dis>nc>on between quan>ta>ve and qualita>ve methods. We will focus on when and how to use quan>ta>ve research and discuss the role and type of variables and sta>s>cal analysis.
- 4. 4 Quan>ta>ve research is ‘Explaining phenomena by collec>ng numerical data that are analyzed using mathema>cally based methods (in par>cular sta>s>cs)’. Aliaga and Gunderson (2000)
- 5. 5 Quantitative research is ‘Explaining phenomena by collecting numerical data that are analyzed using mathematically based methods (in particular statistics)’. Aliaga and Gunderson (2000) Quan>ta>ve research is used to acquire informa>on about a phenomenon (or phenomena) using numerical (quan>ta>ve) data The process is Formal – Objec>ve -‐ Systema>c It is used to describe variables by examining rela>onships among variables -‐ determine cause-‐and-‐effect interac>ons
- 6. 6 Qualita>ve research a^empt to understand specific organiza>on or event and do not involve descrip>on of a sample from a popula>on. It can provide an explicit representa>on of a structure, order and general pa^erns from a group of par>cipants and generates data about human groups in social se`ngs.
- 7. 7 Qualita>ve research a^empt to understand specific organiza>on or event and do not involve descrip>on of a sample from a popula>on. Can provide an explicit representa>on of a structure, order and general pa^erns from a group of par>cipants and generates data about human groups in social se`ngs. No treatments or manipulate variables. Interpreta>on emerge from the par>cipants. Concepts, data collec>on tools, and methods can be adjusted as the research progresses. Provides an understanding through direct experience, repor>ng and interpreta>on from direct conversa>ons.

Main differences are related to data sample, collec>on and analysis. However, the main difference is in the outcome
- 9. 9 It is important to know the type of research methodology you will use (e.g. for your dissertation). However, your research idea will dictate the type of research methodology you use. This will also emphasize your data collection methods. If you are collecting numerical data you are most likely measuring variables and verifying existing theories; hypotheses and questioning them.
- 10. 10 Matching the research design with the research ques1on… Research Type Question Variables Descriptive What is this? Describes the current state of variables Correlational What is happening? Describes the relationship between variables. Quasi-‐Experimental What would happen if? Examines the effect of a variable on other variables. Experimental How can I make it happen? Examines the effect of a variable that the researcher manipulates on other variables.
- 11. 11 § Your research ques>on most likely will determine the type of research design. § The most important part on quan>ta>ve research is not the sta>s>cs. § Both qualita>ve and quan>ta>ve research can explain a phenomenon.
- 12. Aaer listening to this presenta>on, please indicate which of the following research design issues are more relevant for you. 12 1. Choosing a quantitative or qualitative research 2. Selection of type of quantitative research (experimental, quasi- experimental, descriptive, correlational) 3. Collecting data for your research 4. Selection of right statistical analysis
