Researchers often have issues choosing which research method to go with: quantitative or qualitative research methods? Many incorrectly think the two terms can be used interchangeably.

Qualitative research is regarded as exploratory and is used to uncover trends in thoughts and opinions, while quantitative research is used to quantify the problem by way of generating numerical data or data that can be transformed into usable statistics.

At the end of this article, you will understand why you should consider using quantitative research instead of qualitative method in your research surveys.

What is Qualitative Research?

Qualitative research is a process of real-life inquiry that aims to understand social phenomena. It focuses on the “why” and “how” rather than the “what” of social phenomena and depends on the direct experiences of human beings as meaning-making agents in their everyday lives.

It is a scientific research method used to gather non-numerical data. Qualitative research focuses on human behavior from a participant’s point of view.

The three major focus areas are individuals, societies and cultures, and language and communication – employed across academic disciplines, qualitative market research, journalism, business, and so on.

Qualitative researchers use varying methods of inquiry for the study of human phenomena including biography, case study, historical analysis, discourse analysis, ethnography, grounded theory and phenomenology.

The common assumptions are that knowledge is subjective rather than objective and that the researcher learns from the participants in order to understand the meaning of their lives.

Types of Qualitative Research

Just as quantitative, there are varieties of qualitative research methods. We shall look at five types of qualitative research that are widely used in business, education and government organizational models.

  • Narrative Research

This method occurs over extended periods of time and garners information as it happens. It laces a sequence of events, usually from just one or two individuals to form a consistent story.

Narrative research can be considered both a research method in itself but also the phenomenon under study.

Businesses use the narrative method to define buyer personas and use them to identify innovations that appeal to a target market.

  • Ethnographic Research

This method is one of the most popular and widely recognized methods of qualitative research, as it immerses samples in cultures unfamiliar to them. The researcher is also often immersed as a subject for extended periods of time.

The objective is to understand and describe characteristics of cultures the same way anthropologists observe cultural variations among humans.

Ethnographic research allows us to regard and represent the actors as creators and execute their own meanings. The very way in which they tell us about what they do, tells the researcher a great deal about what is meaningful for and in the research. It adds richness and texture to the experience of conducting research.” (Stuart Hannabuss).

The ethnographic method looks at people in their cultural setting; their behavior as well as their words; their interactions with one another and with their social and cultural environment; their language and its symbols; rituals etc. to produce a narrative account of that culture.

  • Historical Research

This method investigates past events in order to learn present patterns and anticipate future choices. It enables the researcher to explore and explain the meanings, phases and characteristics of a phenomenon or process at a particular point of time in the past.

It is not simply the accumulation of dates and facts or even just a description of past happenings but is a flowing and dynamic explanation or description of past events which include an interpretation of these events in an effort to recapture implications, personalities and ideas that have influenced these events (ibid).

The purpose of historical research is to authenticate and explicate the history of any area of human activities, subjects or events by means of scientific processes (Špiláčková, 2012).

Businesses can use historical data of previous ad campaigns alongside their targeted demographic to split-test new campaigns. This would help determine the more effective campaign.

  • Grounded Theory

The grounded theory research method looks at large subject matters and attempts to explain why a course of action progresses the way it did.

Simply put, it seeks to provide an explanation or theory behind the events. Sample sizes are often larger to better establish a theory.

Grounded theory can help inform design decisions by better understanding how a community of users currently use a product or perform tasks. For example, a grounded theory study could involve understanding how software developers use portals to communicate and write code.

Businesses use grounded theory when conducting user or satisfaction surveys that target why consumers use company products or services.

  • Case Study

This involves deep understanding through multiple data sources. Case studies can be explanatory, exploratory, or descriptive. 

Unlike grounded theory, the case study method provides an in-depth look at one test subject. The subject can be a person or family, business or organization, or a town or city.

Businesses often use case studies when marketing to new clients to show how their business solutions solve a problem for the subject.

What is quantitative research?

Quantitative research is used to quantify behaviors, opinions, attitudes, and other variables and make generalizations from a larger population. quantitative research uses quantifiable data to articulate facts and reveal patterns in research. This type of research method involves the use of statistical, mathematical tools to derive results.

When trying to quantify a problem, quantitative data will conclude on its purpose and understand how dominant it is by looking for results that can be projected to a larger population.

This data collection method includes various forms of online, paper, mobile, kiosk surveys; online polls; systematic observations; face-to-face interviews, phone interviews and so on.

Researchers who use quantitative research method are typically looking to quantify the degree and accentuate objective measurements through polls, questionnaires, and surveys, or by manipulating an existing statistical data using computational techniques. 

Summarily, the goal in quantitative research is to understand the relationship between an independent and dependent variable in a population.

5 Types of Quantitative Research

There are four main types of quantitative research designs: correlational, descriptive, experimental and quasi-experimental. But there’s another one; survey research.

  • Descriptive Research

Descriptive research method is more focused on the ‘what’ of the subject matter rather than the ‘why’.i.e. it aims to describe the current status of a variable or phenomenon.  Descriptive research is pretty much as it sounds – it describes circumstances. It can be used to define respondent characteristics, organize comparisons, measure data trends, validate existing conditions.

Data collection is mostly by observation and the researcher does not begin with a hypothesis but, creates one after the data is collected. Albeit very useful, this method cannot draw conclusions from received data and cannot determine cause and effect. 

  • Correlational Research

Correlational research is a non-experimental research method, where the researcher measures two variables, and studies the statistical relationship i.e. the correlation between variables. The researcher ultimately assesses that relationship without influence from any peripheral variable.

Let’s take this example, without classroom teaching, our minds relate to the fact that the ‘louder the jingle of an ice cream truck is, the closer it is to use. We also memorize the jingle that comes from the speakers of the truck. And if there are multiple ice cream trucks in the area with different jingles, we would be able to memorize all of it and relate particular jingles to particular trucks. This is how the correlational method works.

The most prominent feature of correlational research is that the two variables are measured – neither is manipulated.

A correlation has direction and can be either positive or negative. It can also differ in the degree or strength of the relationship.

  • Experimental Research

Often referred to as ‘true experimentation’, this type of research method uses a scientific method to establish a cause-effect relationship among a group of variables.

It is commonly defined as a type of research where the scientist actively influences something to observe the consequences.

It is a systematic and scientific approach to research in which the researcher manipulates one or more variables, and controls/randomizes any change in other variables.

Experimental research is commonly used in sciences such as sociology and psychology, physics, chemistry, biology and medicine and so on.

  • Quasi-experimental Research

The prefix quasi means “resembling”. Quasi-experimental research resembles experimental research but is not a true experimental research. It is often referred to as ‘Causal-Comparative’.

In this type of research, the researcher seeks to establish a cause-effect relationship between two variables and manipulates the independent variable.

Although the independent variable is manipulated, participants are not randomly assigned to conditions or orders of conditions (Cook & Campbell, 1979).

Abraham & MacDonald (2011) states:

Quasi-experimental research is similar to experimental research in that there is manipulation of an independent variable. It differs from experimental research because either there is no control group, no random selection, no random assignment, and/or no active manipulation.”

Quasi-experimental involves ‘comparison.’ The study of two or more groups is done without focusing on their relationship.


  • Survey Research

Survey Research uses interviews, questionnaires, and sampling polls to get a sense of behavior with concentrated precision. Researchers are able to judge behavior and then present the findings in an accurate way.

Survey research can be conducted around one group specifically or used to compare several groups. When conducting survey research, it is imperative that the researcher samples random people. This allows for more accurate findings across a greater number of respondents.

This kind of research can be done in person, over the phone, or through email. They can be self-administered.

Why choose Quantitative Research over Qualitative Research?

Quantitative research is more preferred over qualitative research because it is more scientific, objective, fast, focused and acceptable. However, qualitative research is used when the researcher has no idea what to expect. It is used to define the problem or develop and approach to the problem.

  • More scientific: A large amount of data is gathered and then analyzed statistically. This almost erases bias, and if more researchers ran the analysis on the data, they would always end up with the same numbers at the end of it.
  • Control-sensitive: The researcher has more control over how the data is gathered and is more distant from the experiment. An outside perspective is gained using this method.
  • Less biased/objective: The research aims for objectivity i.e. without bias, and is separated from the data. Researcher has clearly defined research questions to which objective answers are sought.
  • Focused: The design of the study is determined before it begins and research is used to test a theory and ultimately support or reject it.
  • Deals with larger samples: The results are based on larger sample sizes that are representative of the population. The large sample size is used to gain statistically valid results in customer insight.
  • Repeatable: The research study can usually be replicated or repeated, given its high reliability.
  • Arranged in simple analytical methods: Received data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms.
  • Generalizable: Project can be used to generalize concepts more widely, predict future results, or investigate causal relationships. Findings can be generalized if selection process is well-designed and sample is representative of a study population.
  • Relatable: Quantitative research aims to make predictions, establish facts and test hypotheses that have already been stated. It aims to find evidence which supports or does not support an existing hypothesis. It tests and validates already constructed theories about how and why phenomena occur.
  • More structured: Researcher uses tools, such as questionnaires or equipment to collect numerical data.
  • Pertinent in later stages of research: Quantitative research is usually recommended in later stages of research because it produces more reliable results.
  • Consistent with data: With quantitative research, you may be getting data that is precise, reliable and consistent, quantitative and numerical.
  • More acceptable: It may have higher credibility among many influential people (e.g., administrators, politicians, sponsors, donors)
  • Fast: Data collection using quantitative methods is relatively quick (e.g., telephone interviews). Also, data analysis is relatively less time consuming (using statistical software).
  • Useful for decision making: Data from quantitative research—such as market size, demographics, and user preferences—provides important information for business decisions.

There’s no such thing as qualitative data. Everything is either 1 or 0” – Fred Kerlinger

When to use Quantitative Research Method

Quantitative research ends with conclusions/recommendations, as it tries to quantify a problem and understand how prevalent it is by looking for results that can be projected to a larger population. It can help you see the big picture.

A researcher may want to determine the link between income and whether or not more people pay taxes. This is a question that asks “how many” and seeks to confirm a hypothesis.

The method will be structured and consistent during data collection, most likely using a questionnaire with closed-ended questions. The data can be used to look for cause and effect relationships and therefore, can be used to make predictions.

The results will provide numerical data that can be analyzed statistically as the researcher looks for a correlation between income and tax payers. Quantitative methodology would best apply to this research problem.

Use quantitative research methods such as A/B testing for validating or choosing a design based on user satisfaction scores, perceived usability measures, and/or task performance. The data received is statistically valid and can be generalized to the entire user population.

Basically, quantitative research is helpful when you get feedback from more than a handful of participants; need to present a more convincing case to an audience; you want to gather feedback from a diverse population of users NOT all located in the same place; you have a limited budget.


When to use Qualitative Research

Qualitative research is explanatory and is used when the researcher has no idea what to expect. It is used to define the problem or develop and approach to the problem.

It is used to delve deeper into issues of interest. Qualitative data adds the details and can also give a human voice to your results.

Use this type of research method if you want to do in-depth interviews, want to analyze issues affecting focus groups, want uninterrupted observation and ethnographic participation.

You can use it to initiate your research by discovering the problems or opportunities people are thinking about. Those ideas can later become hypotheses.

Quotes from open-ended questions in qualitative research can put a human voice to the objective numbers and trends in your results. Many times, it helps to hear your customers describe your organization honestly which helps point out blind spots.

Choose qualitative research if you want to capture the language and imagery customers use to describe and can easily relate with a brand, product, service and so on.

How to Interpret Qualitative Research Data

Qualitative data consists of words, observations, pictures, and symbols. Analyzing received data typically occurs simultaneously with the data collection.

See qualitative research can be analysed and interpreted with the following steps:

  1. Data familiarity: As a researcher, you should read and understand the data, noting impressions, look for meaning and weed out unnecessary data.
  2. Identify key questions you want to answer through the analysis. One way to focus the analysis is to examine the data as it relates to a case, an individual, or a particular group.
  3. Code and index the data by identifying themes and patterns that may consist of ideas, concepts, behaviors, interactions, phrases and so on. Then, assign a code to pieces of data to label the data and make it easier to manage.
  4. After that, you should identify patterns and make connections. Identify the themes, look for relative importance of responses received and try to find explanations from the data.
  5. The last thing to do is to interpret the data and explain findings. You can develop a list of key ideas or use models to explain the findings.

How to Interpret Quantitative Research Data

Quantitative research methods result in data that provides quantifiable, objective, and easy to interpret results. Quantitative data can be analyzed in several ways.

The first thing to do for quantitative data is to identify the scales of measurement. There are four levels of measurement: nominal, ordinal, interval, ratio (scale).

Identifying the scale of measurement helps determine how best to organize the data. It can be entered into a spreadsheet and managed in a way that gives meaning to the data.

The next thing to do is to use some of the quantitative data analysis procedures – data tabulation, descriptive data, data disaggregation, moderate and advanced analytics.

Case Study of Quantitative Research

Geramian et al considered the prevalent problem of drug abuse in Iran especially in adolescents and youth, and conducted a study to assess the status of drug abuse among high school students in Isfahan Province, Iran.

The study was conducted through a questionnaire in 2009 in 20 cities. Study population was high school students aged 14–18 years. The required sample size (considering α = 0.05) was calculated as 6489 students, which was increased to 7137 students with consideration of the dropout rate of 10%.

The study identified the degree of drug abuse according to age, gender and cities. There was also an assessment of the type of drugs used, the most common causes of drug abuse for the first time, the most important cause of drug abuse, mean age of abusers and mean age at first abuse, knowledge about short and long-term complications of narcotics and stimulants, common time and locations of drug abuse, and the most common routes of drug abuse according to gender as well as urban and rural areas of Isfahan Province.

Using the results of the research, the knowledge, attitude, and practice of students toward drug abuse were identified.

Case study of Qualitative Research

A good example of qualitative research is Alan Peshkin’s 1986 book God’s Choice: The Total World of a Fundamentalist Christian School published by the University of Chicago Press.

Peshkin examines the culture of Bethany Baptist Academy by interviewing the students, parents, teachers, and members of the community; and observing for eighteen months – to provide a comprehensive and in-depth analysis of Christian schooling as an alternative to public education.

Peshkin’s work represents qualitative research as it is an in-depth study using tools such as observations and unstructured interviews, aimed at securing descriptive or non-quantifiable data on Bethany Baptist Academy specifically, without attempting to generalize the findings to other schools.

Peshkin describes Bethany Baptist Academy as having institutional unity of purpose, a dedicated faculty, an administration that backs teachers in enforcing classroom disciplines, cheerful students, rigorous homework, committed parents, and above all grounded in positive moral values and a character-building environment.

According to Peshkin, the school focuses on providing ‘wholesome’ lives for students, separate from a secular world, however interacting with the same world.

He adds that there is a lack of cultural diversity in the Academy and the counterproductive method of training students in one-dimensional thought, where students are not allowed to question the viewpoints of their teacher’s biblical interpretations; not forgetting the presence of a heavily censored library.

The school also ignores state regulations for schools, such as state assessments, certification and minimum wages for teachers, while enforcing compulsory volunteer tasks for teachers. Peshkin however paints the school in a positive light and holds that public schools have much to learn from such schools.
