Quantitative Research Design| Qualitative Research Design


Scientific research is defined as the method of finding a solution to a particular problem one can identify. Today there are various methods of formulating a research design for the study. But two broad data collection and interpretation approaches in research are qualitative and quantitative research. The elementary method of conducting research was quantitative, but recently, the qualitative method of research has also familiar among the investigators.

Quantitative Research

Quantitative Research design

Quantitative research is a type of systematic study in which investigators gathered empirical data or information by clear phenomena using statistical tools or computational techniques. Data are acquired individual and group experiences with the use of different factors of investigation. This type of research is mostly used in natural and social sciences: biology, chemistry, psychology, economics, sociology, marketing, etc. Data can be described in number, not in word, and gathered the structured format of data.

Example of quantitative research

For example, you need to identify the weight of all students in your classroom. To conduct this research you have to do a survey by phone call and asked them for their weight or you physically take the weight of each and every student. Both types of research are the example of quantities research which helps you to obtain the numerical data and your aim of assessing the weight of each student was achieved. 

Qualitative Research design

Unlike quantitative reach, qualitative research is usually unstructured and probing in nature. In qualitative research data generated is conditional based and cannot be counted. The data can be described in a word, not in number. Qualitative research is generally focused on recognizing the research question and method of research to generate non-numeral data. Qualitative the research was initially used in a psychological study, the people’s beliefs, experiences, attitudes behaviors, and interactions when it’s found tedious to evaluate human behavior in a numeric way, but today it’s used in other fields of research as well.  

Example of qualitative research

For example, you are a keynote speaker in a conference, after finishing your lecture your question was, “how was the lecture” let’s assume there are more than 300 audions and all refer a card of comments like very informative, less informative, out of theme, great, boring, etc. “when the manager asked for feedback” You are scratching your head because you have not any knowledge how to summarize the data. You have many options, First, assemble all card and handover to the manager, or second, take a look on few of them and guess the key feedback or thirdly, you have one step further and noted all response in a spreadsheet using code analyses the data and present your feedback as; very informative 50%, less informative 30%, out of theme 10%, great 5%, boring%, Now you are a great teacher and this the qualitative data of your feedback from audios.

Notion: Here’s a helpful hint to remember the difference between these two words: quantitative and qualitative. After all, both words are almost identical. Remember that quantitative has a sound of “quantity” means in number and qualitative sound “quality” means in rank.
