Quantitative vs. Qualitative Research - Video & Lesson

Qualitative research often opens up new options and ideas that quantitative research cannot due to its closed-ended nature.This gives respondents an opportunity to deal with issues that they have thought about, or think are important but have not been dealt with by the interviewer. 9 This can often lead to the discovery of new, unanticipated information.There are many similarities between clinical encounters and research interviews, in that both employ similar interpersonal skills, such as questioning, conversing and listening.

This is called triangulation, and is employed in order to collect data that provide sufficient data, provide more information on a phenomenon or enhance deeper analysis and understanding of a research study.While quantitative research is based on numbers and mathematical calculations (aka quantitative data ), qualitative research is based on written or spoken narratives (or qualitative data ).But it is relatively easier to analyze survey responses from thousands of people if the questions are closed-ended and responses can be mathematically encoded in, say, rating scales or preference ranks.Structured interviews are, essentially, verbally administered questionnaires, in which a list of predetermined questions are asked, with little or no variation and with no scope for follow-up questions to responses that warrant further elaboration.

Main forms of data collection under each strategy are given in the following chart.

Qualitative research gathers data that is free-form and non-numerical, such as diaries, open-ended questionnaires, interviews and observations that are not coded using a numerical system.General educational research overviews typically include several chapters on data collection, organized into qualitative and quantitative approaches.Introduction Having explored the nature and purpose of qualitative research in the previous paper, this paper explores methods of data collection used in qualitative research.Addressing a special needs population difficult to access and sample through quantitative measures, Robinson et al. 17 used focus groups to investigate the oral health-related attitudes of drug users, exploring the priorities, understandings and barriers to care they encounter.Chadwick 4 Interviews and focus groups are the most common methods of data collection used in qualitative healthcare research Interviews can be used to explore the views, experiences, beliefs and motivations of individual participants Focus group use group dynamics to generate qualitative data.However, the transcription of focus groups is more complex and time consuming than in one-to-one interviews, and each hour of audio can take up to eight hours to transcribe and generate approximately 100 pages of text.

Moderating Moderating a focus group looks easy when done well, but requires a complex set of skills, which are related to the following principles: 15 Participants have valuable views and the ability to respond actively, positively and respectfully.It is hard, for example, to conduct in-depth interviews with thousands of people or to analyze their responses to open-ended questions.

Data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated.
