Qualitative Data Analysis

Qualitative data can be defined as non-numerical and unstructured data that is collected from qualitative research methods, such as open-ended survey questions, in-depth interviews, focus groups, direct observation, and content analysis (video, picture or document). The data collected from these methods is typically in the form of typed text, transcripts or recordings that must be examined to identify key themes and insights. The process of examining and interpreting qualitative data is known as qualitative data analysis.

The most common type of qualitative data analysis is content analysis. Content analysis refers to the process of categorizing text, verbal or behavioral data to classify, summarize and tabulate the data. For example, to analyze focus group data, researchers might review transcripts or recordings and group similar sentiments together into categories. They would then assign each of those categories a “code.”

Coding Qualitative Data

Coding is an integral part of qualitative data analysis. Coding can be defined as the labeling and organizing of qualitative data to identify themes and patterns. The purpose of coding is to provide structure to free-form data so that it can be examined in a systematic way.

A code can be a word or a phrase that represents a recurring theme or idea in the data. The code name should be meaningful and capture the essence of the free-form response or observation. For example, coding the open-ended responses to a survey question might look like the following:

Assigning codes helps capture what each qualitative response is about. Researchers can then analyze those codes and begin to build on the themes and patterns that surface to gain comprehensive insights into the data. Although the process of developing and assigning codes can be laborious and time-consuming, ultimately it helps reduce the amount of data that must be reviewed or taken into account in the final analysis.

Automated Coding of Qualitative Data

There are two methods of coding qualitative data: automated coding and manual coding.

Automated coding uses qualitative data analysis software to quickly analyze and code qualitative data. The software leverages machine learning, artificial intelligence (AI), and natural language processing to determine themes and create codes without any advance setup or pre-planning. The algorithms learn as they go.

Some of the perceived benefits of automated coding include the elimination of researcher bias, the ability to process large amounts of data, and significant time-savings. Manual coding remains popular, however, due to its perceived higher accuracy.

Manual Coding of Qualitative Data

Manual coding requires researchers to read through their data and manually develop and assign codes and themes. Although manual coding is time-consuming, it can help streamline the overall analysis process. Creating codes requires the researcher to decide which data is relevant and why, reducing the amount of data that must be considered in the final analysis.

Before starting coding, researchers have to decide if they want to use a deductive or inductive coding method.

Deductive Coding

In deductive coding, researchers start with a predefined set of codes or a codebook developed before analyzing the research data. This set could be based on the research questions or an existing research framework or theory. For example, if the research question is why a consumer purchased a specific product, the researcher might predefine a list of codes that includes price, quality, brand, etc. With this list in mind, the researcher would then read through the research data and simply assign the predefined codes.

Inductive Coding

Inductive coding involves building a list of codes or a codebook from scratch based on the research data. Rather than starting with a plan for what the codes should be, researchers allow the themes and theories to emerge from the data itself.

Inductive coding is often more difficult but can be less prone to bias than deductive coding, because the researcher does not start the analysis process with any preconceived notions about what they might read or hear.

In practice, research studies often combine deductive and inductive coding, starting with a predefined list of codes but then inductively modifying and adding to that list as analysis ensues.

Steps for Manually Coding Qualitative Data

Coding is an important step in moving from the raw data to the findings. There is no right or wrong way to code a set of data, and the process can vary significantly depending on the data collected and the objective of the research.

In general, however, it involves some variation of the following steps:

1. First pass: Researchers first read through or listen to all the data and assign codes to general phrases, ideas or categories that surface. The codes might represent the participant’s own words, a label, description, definition, or category name. The purpose of this round is to gain an overall understanding of what the data is about. This step should be relatively fast and easy since the researcher will be evolving and updating the codes in the rounds to follow.
2. Line-by-line coding: In the second pass through the data, the researcher should comb through the data line-by-line, refining the list of codes and adding detail. While the first pass at coding is fast and loose, this second round is about reanalyzing, renaming, merging codes, finding patterns, and getting closer to developing theories and concepts.
3. Creating categories and themes: After line-by-line coding, it is time to start grouping codes together into categories and developing themes. Codes might be grouped together according to similarity or if they pertain to the same topic or general concept. The researcher then looks through the categories, keeping a close eye out for any themes or patterns that emerge across the data set. Within these themes lies the overall narrative of the research.

Difference Between Quantitative and Qualitative Data

The primary difference between quantitative and qualitative data is that quantitative data represents data that can easily be measured or quantified, such as the number of people who have bought a product. Qualitative data represent opinions or feelings and cannot be represented by a numerical statistic such as an average.

For example, if a survey asked 500 respondents the question “Did you buy ice cream today?”, and 300 responded ‘yes’ while 200 responded ‘no’, we would know that 300/500 or 60% bought milk, a quantitative fact. If the same survey asked an open-ended follow-up question: “Why did you choose the brand of ice cream you bought?” you would receive qualitative insights that are unique to each respondent. One person may say, ‘I liked the packaging and label colors’ while another may state, ‘It was the first one I saw on the shelf.’ These descriptive insights cannot easily be quantified into numbers, so they are qualitative.

Qualitative vs Quantitative Analysis

Another difference between quantitative and qualitative research is how data is analyzed. While quantitative data can be analyzed statistically and calculated into averages, means, and other numerical data points, qualitative data analysis involves a more complex system.

To glean insights from qualitative data, researchers conduct a manual analysis of datasets and often code responses into categories. For example, to analyze focus group data, researchers could review transcripts or recordings and group similar sentiments together into categories. Due to this manual process, qualitative data analysis is a longer and more labor-intensive process than quantitative data analysis, which is another factor to keep in mind when deciding what type of data to collect.

While some methods such as focus groups typically collect qualitative data, other methods such as surveys often collect quantitative and qualitative data within one survey instrument, as outlined below.

Quantitative Data Examples

Quantitative data is collected through several methods, including surveys, controlled experiments, and certain observation types. Quantitative data types include:

• Yes/no questions
  • “Did you go to work today? 1) Yes 2) No”
• Single choice questions
  • “What is your favorite flavor of ice cream? 1) Vanilla 2) Chocolate 3) Cookie Dough 4) Peppermint 5) Chocolate chip”
• Multiple choice or ‘select-all-that-apply’ questions
  • “Which of the following products did you buy last week? 1) Toothpaste 2) Soap 3) Vegetables 4) Meat 5) Grains 6) Bread”
• Ranking questions
  • “Please rank the statement ‘I enjoy ice cream’ from 1: Strongly disagree to 5: Strongly agree”
• Numerical range questions
  • “How much money did you spend at the grocery store today? Please respond with a dollar amount”
• Quantitative observations
  • Observations that can be categorized or quantified, such as the number of times a person checks their phone in a given time. These observations often take place in a controlled environment.

As all of these question types collect data that fit into set categories or can be calculated into averages and other statistics, they are quantitative.

Qualitative Data Examples

Qualitative data can also be collected through certain types of survey questions, in addition to interviews and focus groups. Examples of qualitative data include:

• Open-ended survey questions
  • “Why is cookie dough your favorite flavor of ice cream?”
• Unstructured or semi-structured interviews
  • Unstructured and semi-structured interviews allow topics and questions to flow naturally, rather than only asking questions from a set question list in a specific order.
• Focus groups
  • In focus groups, multiple people have a discussion (in-person or via an online or mobile-based chat group) facilitated by a trained moderator who gives prompts to start conversations.
• Unstructured observation
  • Researchers can gather qualitative data through unstructured observations, such as observing participants as they partake in certain activities such as shopping.
• Documents or content analysis
  • Reviewing documents to better understand a particular topic or categorize elements of documents is a type of qualitative research.

Data collected from these methods and question types do not provide numerical statistics but instead, give insights that are often longer and more detailed than their quantitative counterparts.

When Should I Use Quantitative or Qualitative Research?

Once you understand the types of data provided by qualitative and quantitative research and the methods for each, it’s essential to understand how to utilize each type of data best. Generally, quantitative data is used to answer precise questions and prove or disprove hypotheses, while qualitative data provides richer insights on a smaller scale.

Qualitative research is often conducted at the beginning of a study when researchers are looking to gather broad, unstructured information on a topic to create a hypothesis, which can then be more clearly answered by quantitative research. Qualitative data collected through unstructured interviews or focus groups can also inform the development of a more structured questionnaire administered to a larger group.

For example, a focus on different ice cream brands may uncover that participants generally consider price and packaging first. That information can then be inputted into a quantitative question: “Which is more important to you when buying ice cream? 1) Price 2) Packaging” administered to a nationally representative sample.

Qualitative data may also be used as part of a mixed-methods research study to add additional context to quantitative data. A researcher may administer both a quantitative questionnaire and conduct a qualitative analysis of interviews with subject-matter experts to form a more robust conclusion.

Surveys can also be split between qualitative and quantitative; Many surveys are mostly quantitative questions that can be quickly analyzed, plus one or two qualitative questions that provide deeper insights into the topic being studied.
