All aspects of the study are carefully designed before data is collected. Researcher is the data gathering instrument. Researcher uses tools, such as questionnaires or equipment to collect numerical data.

Data is in the form of words, pictures or objects. Data is in the form of numbers and statistics. Qualitative data is more 'rich', time consuming, and less able to be generalized. Quantitative data is more efficient, able to test hypotheses, but may miss contextual detail. Researcher tends to become subjectively immersed in the subject matter. Researcher tends to remain objectively separated from the subject matter.

Qualitative versus Quantitative Research: Key Points in a Classic Debate. James Neill Last updated: Everything is either 1 or 0" - Fred Kerlinger.

The aim is a complete, detailed description. The focus of this set of modules is qualitative research. However, the following introductory video, A Brief Introduction to Research Design, offers a brief explanation of each method and a comparison. Quantitative methods are used to examine the relationship between variables with the primary goal being to analyze and represent that relationship mathematically through statistical analysis.

This is the type of research approach most commonly used in scientific research problems. Following is a list of characteristics and advantages of using quantitative methods: There are a variety of quantitative methods and sampling techniques that will be discussed in detail in the other modules in this unit. However, following are examples of research questions where quantitative methods may be appropriately applied: The collection of numerical data through quantitative research methods lends itself well to large variety of research questions.

The following modules in this series will explore when to choose quantitative methods, how to write a good research question, types of quantitative methods, data analysis, ethics and many other topics that will lead to better understanding of quantitative research. Introduction to Quantitative Research — The following PDF is an article that provides an introduction to quantitative research.

Overview of Quantitative Research — Following is a narrated PowerPoint presentation that provides an excellent overview of quantitative research and the issues that will be discussed in these Research Ready modules. A Basic Introduction — Following is a link to a Slideshare presentation that offers and overview to quantitative research and data. Strengths and Weaknesses of Quantitative Research — This link provides lists of the strengths and weaknesses of quantitative research.

Research Methods — This resource describes the basic characteristics of quantitative research and gives an overview of methodologies, as well as a comparison with qualitative research. Qualitative and Quantitative Research — The link below contains a chart that describes the characteristics of quantitative research and compares them the characteristics of qualitative research.

Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality. Quantitative research deals in numbers, logic, and an objective stance. What are quantitative methods of research? What is its definition, when are these methods used and what are its characteristics? This article defines quantitative methods and lists seven characteristics that discriminate these research methods from qualitative research approaches.
