10 Advantages and Disadvantages of Qualitative Research

Research is about gathering data so that it can inform meaningful decisions. In the workplace, this can be invaluable in allowing informed decision-making that will meet with wider strategic organizational goals.

However, research comes in a variety of guises and, depending on the methodologies applied, can achieve different ends. There are broadly two key approaches to research -- qualitative and quantitative.

Research Approaches

Understanding Different Research Approaches

Research approaches are the frameworks that guide the research process, from defining the research question to collecting and analyzing data.

There are two primary research approaches: Qualitative and Quantitative.

Understanding the differences between these approaches is crucial for selecting the most suitable method for a research study.

Qualitative research approaches focus on exploring and understanding the meaning and context of social phenomena. They involve collecting and analyzing non-numerical data, such as text, images, and observations, to gain a deeper understanding of the research topic. Qualitative research methods are often used in exploratory studies, where the goal is to gain a rich and detailed understanding of a particular phenomenon. For instance, qualitative researchers might conduct in-depth interviews or ethnography, a qualitative research design that involves the researcher immersing themselves in the participants' environment, to gather insights into people’s experiences and perspectives. Grounded Theory in qualitative research involves generating a theoretical model based on observations of a study population.

Quantitative research approaches, on the other hand, focus on measuring and analyzing numerical data to identify patterns and trends. They involve collecting and analyzing data using statistical methods, such as surveys, experiments, and statistical analysis. Quantitative research methods are often used in confirmatory studies, where the goal is to test a hypothesis or theory. Quantitative research generally follows a rigid structure to test the links or relationships between different variables. For example, a quantitative study might use a survey to collect data from a large sample and then apply statistical analysis to determine the prevalence of certain behaviors or attitudes.

Mixed-methods research approaches combine both qualitative and quantitative methods to provide a more comprehensive understanding of the research topic. This approach is useful when the research question requires both in-depth exploration and numerical analysis. By integrating qualitative and quantitative data, researchers can gain a fuller picture of the phenomenon under study, leveraging the strengths of both approaches. Mixed methods research provides higher validity and reliability than single-method approaches, making it a robust choice for complex research questions. Mixed methods research avoids criticisms directed at qualitative and quantitative research.

Qualitative vs. Quantitative – What’s the Difference?

Data Types

When it comes to research, the type of data collected plays a crucial role in shaping the study’s outcomes and insights. Qualitative and quantitative research differ significantly in the types of data they collect and analyze.

Qualitative Data: This type of data is non-numerical and often descriptive. It includes text, images, audio, and video recordings, as well as observations and notes. Qualitative data is rich in detail and context, providing deep insights into the subject matter. For example, transcripts from interviews, notes from focus groups, and field observations are all forms of qualitative data. This data type allows researchers to explore complex phenomena, understand underlying motivations, and capture the nuances of human experiences. Qualitative data is analyzed by grouping the data into categories and themes.

Quantitative Data: In contrast, quantitative data is numerical and can be measured and quantified. It includes data that can be counted or expressed in numbers, such as survey responses, test scores, and statistical records. Quantitative data is often used to identify patterns, test hypotheses, and make generalizations. For instance, a quantitative study might collect data on the number of hours employees work each week and use statistical analysis to determine the average work hours and identify any significant differences between groups. Quantitative data collection methods include experiments and polls.

Understanding the differences between qualitative and quantitative data is essential for selecting the appropriate research method. While qualitative data provides depth and context, quantitative data offers precision and the ability to generalize findings. The key difference is that qualitative research seeks to understand meanings, while quantitative research aims to quantify variables. By combining both types of data, researchers can achieve a more comprehensive understanding of their research questions, leveraging the strengths of each approach.

Qualitative Research Methods vs Quantitative – what's the difference?

Qualitative Research is at the touchy-feely end of the spectrum. Understanding the differences between quantitative and qualitative research approaches is crucial for selecting the most suitable method for a research study. It’s not so much about bean-counting and much more about capturing people’s opinions and emotions.

“Research following a qualitative approach is exploratory and seeks to explain ‘how’ and ‘why’ a particular phenomenon, or behavior, operates as it does in a particular context.”(simplypsychology.org)

Examples of the way qualitative research is often gathered includes: Focus groups allow researchers to gather diverse perspectives on a topic in a group setting.

Interviews

Interviews are a conversation based inquiry where questions are used to obtain information from participants. Interviews are typically structured to meet the researcher’s objectives. Interviews are a key component of a qualitative study, allowing researchers to gather in-depth insights into participants' experiences and perceptions.

Focus Groups

Focus group discussions are a common qualitative research strategy. In a focus group discussion, the interviewer talks to a group of people about their thoughts, opinions, beliefs, and attitudes towards a topic. Participants are typically a group who are similar in some way, such as income, education, or career. In the context of a company, the group dynamic is likely their common experience of the workplace. Focus groups are often used in qualitative studies to explore the subjective nature of participants' opinions and attitudes.

Observation

Observation is a systematic research method in which researchers look at the activity of their subjects in their typical environment. Observation gives direct information about your research. Using observation can capture information that participants may not think to reveal or see as important during interviews/focus groups. Observation is a qualitative method that allows researchers to capture real-time data and adapt their approach as new information emerges.

Existing Documents

This is also called secondary data. A qualitative data collection method entails extracting relevant data from existing documents. This data can then be analyzed using a qualitative data analysis method called content analysis. Existing documents might be work documents, work email, or any other material relevant to the organization.

Quantitative Research is the ‘bean-counting' bit of the research spectrum. This isn't to demean its value. Now encompassed by the term ‘People Analytics', it plays an equally important role as a tool for business decision-making.

Organizations can use a variety of quantitative data-gathering methods to track productivity. In turn, this can help:

• To rank employees and work units
• To award raises or promotions.
• To measure and justify termination or disciplining of staff
• To measure productivity
• To measure group/individual targets

Examples might include measuring workforce productivity. If Widget Makers Inc., has two production lines and Line A is producing 25% more per day than Line B, capturing this data immediately informs management/HR of potential issues. Is the slower production on Line B due to human factors or is there a production process issue?

Quantitative Research can help capture real-time activities in the workplace and point towards what needs management attention.

The Pros & Cons of the Qualitative approach

By its nature, qualitative research is far more experiential and focused on capturing people’s feelings and views. This undoubtedly has value, but it can also bring many more challenges than simply capturing quantitative data. Qualitative research questions often focus on open-ended inquiries such as how and why. Here are a few challenges and strengths of qualitative research to consider:

While qualitative research provides depth and context, quantitative studies offer the ability to quickly analyze data and present findings through statistical means.

The Pros

1. Qualitative Research can capture changing attitudes within a target group such as consumers of a product or service, or attitudes in the workplace.

2. Qualitative approaches to research are not bound by the limitations of quantitative methods. If responses don't fit the researcher's expectation that's equally useful qualitative data to add context and perhaps explain something that numbers alone are unable to reveal.

3. Qualitative Research provides a much more flexible approach. If useful insights are not being captured researchers can quickly adapt questions, change the setting or any other variable to improve responses.

4. Qualitative data capture allows researchers to be far more speculative about what areas they choose to investigate and how to do so. It allows data capture to be prompted by a researcher's instinctive or ‘gut feel' for where good information will be found.

Qualitative research can be more targeted. If you want to compare productivity across an entire organization, all parts, process, and participants need to be accounted for. Qualitative research can be far more concentrated, sampling specific groups and key points in a company to gather meaningful data. This can both speed the process of data capture and keep the costs of data-gathering down.

The Cons

1. Sample size can be a big issue. If you seek to infer from a sample of, for example, 200 employees, based upon a sample of 5 employees, this raises the question of whether sampling will provide a true reflection of the views of the remaining 97.5% of the company?

2. Sample bias - HR departments will have competing agendas. One argument against qualitative methods alone is that HR tasked with finding the views of the workforce may be influenced both consciously or unconsciously, to select a sample that favors an anticipated outcome.

3. Self-selection bias may arise where companies ask staff to volunteer their views. Whether in a paper, online survey, or focus group, if an HR department calls for participants there will be the issue of staff putting themselves forward. The argument goes that this group, in self-selecting itself, rather than being a randomly selected snapshot of a department, will inevitably have narrowed its relevance to those that typically are willing to come forward with their views. Quantitative data is gathered whether someone volunteered or not.

4. The artificiality of qualitative data capture. The act of bringing together a group is inevitably outside of the typical ‘norms' of everyday work life and culture and may influence the participants in unforeseen ways.

5. Are the right questions being posed to participants? You can only get answers to questions you think to ask. In qualitative approaches, asking about “how” and “why” can be hugely informative, but if researchers don't ask, that insight may be missed.

The reality is that any research approach has both pros and cons. The art of effective and meaningful data gathering is thus to be aware of the limitations and strengths of each method.

In the case of Qualitative research, its value is inextricably linked to the number-crunching that is Quantitative data. One is the Ying to the other's Yang. Each can only provide half of the picture, but together, you get a more complete view of what's occurring within an organization.
