Quantitative vs Qualitative

Quantitative vs Qualitative

Data analysis is extensive, exploratory, and extremely challenging. When conducting research, we often find that we are unaware of the differences between research methods. However, when we sit back and try to condense data analysis, we immediately realize that there are only two approaches to choose from: qualitative data and quantitative data. The main purpose of the Quantitative vs Qualitative article is to examine the similarities and differences Between these two concepts.

All data that is ever analyzed is composed of these two very different categories of data. Many people are under the impression that the two terms are interchangeable. So what distinguishes qualitative research from quantitative research?

Quantitative Data

Any information that can be quantified is called quantitative data. Quantitative data can be counted, measured, and given a numerical value. Charts and numbers are used to represent quantitative research. This type of data provides information about the answer to questions such as “how many,” “how much,” or “how often.”

Quantitative Data – Examples

  • How many girls will watch the movie?
  • How much money has it brought in since 2010?
  • How many students are in the class?
  • How much oil does Canada export per year?
  • How often do you go to a concert?
  • How much does service cost at stadiums?
  • What is the relationship between drug use and age?

You will conduct statistical studies to examine and interpret quantitative data: Experiments, numerical observations, and closed-question surveys are examples of common quantitative information.

Qualitative Data

Qualitative information describes characteristics or values. It is collected through observation, interviews, or surveys and often takes the form of stories. Analyzing qualitative data allows us to explore ideas and further explain quantitative findings. One of the most popular qualitative research techniques for collecting data is focus groups. A focus group consists of at least five respondents who act as clusters, such as responses to an open-ended survey or notes from a focus group about the quality of food in a restaurant. The most common techniques used in this research method are Focus group – case study – ethnographic research – grounded theory – narrative and phenomenology.

It should be noted that qualitative research goes a step further than quantitative research in measuring the superficial characteristics of what the feedback data reflect, such as opinions, motives, and reasons. Conclusions can be drawn from qualitative analysis, some of which may be subjective. It puts the quantitative feedback data in context and answers the “why” behind the data. Through this type of research, you can gain comprehensive knowledge on topics that are difficult to understand.

Qualitative Data – Examples

Your analysis can get additional context if you describe the data. Here are some simple examples of descriptive qualitative data:
Jessica has bright blue eyes and light brown hair.
The room had light brown wallpaper and was cool and dark.
The blue flowers smelled of lilac and lavender.
The white, chubby dog had beautiful whiskers.
The tall gentleman wore a suit with blue stripes.
The bed was nice and comfortable, made of white leather.

Qualitative research vs Quantitative research

Quantitative and qualitative data differ mainly in what they represent, how they are collected, and how they are examined. A statistical and numerical analysis of data is quantitative research (numbers and statistics). In contrast, qualitative research focuses on open-ended and non-numerical data (concepts, descriptions, meanings, words, etc.). Let’s use a table that highlights the most important differences between these two methods.

Summary of Quantitative vs Qualitative

Quantitative information tells us how many, how much, or how often something occurs. Qualitative data helps us better understand why, how, or what is behind certain behaviors. Quantitative information is based on numbers and can be counted or measured. Qualitative data is descriptive, language-based, and interpretation-based.

While the sample in qualitative analysis is limited and cannot represent the entire population, the sample in quantitative analysis is large and can. In qualitative data collection, the researcher usually uses surveys or interviews, while in quantitative data collection, experiments and measurements are conducted.

Quantitative analysis collects all quantifiable variables such as density, length, height, and weight, while qualitative analysis collects typical data such as color, religion, sexuality, and so on. Qualitative research is subjective and exploratory, while quantitative analysis is conclusive and unbiased.
