What is mixed methods research?
When starting the research process, researchers sometimes think they have to decide whether qualitative research or quantitative research is more appropriate for their research design. However, the more important question is whether the methods they employ in data collection and analysis sufficiently capture the phenomenon they want to study. In some cases, answering this question requires using multiple methods of research. Mixed methods research is a research paradigm that involves collecting qualitative data and quantitative data on the same object of inquiry. Researchers who employ mixed methods research synthesize qualitative findings with quantitative findings to achieve a better understanding.
Let's look at the established research paradigms, then mixed methods research, why it's useful, and which research methods complement each other. Then we'll examine how ATLAS.ti can help you execute a mixed methods design.
What is a mixed methods design?
Mixed methods research is followed out of the need to understand concepts or phenomena at a deep level. A standalone quantitative study or qualitative study can provide great insight. Still, one method alone may not be able to capture all knowledge necessary to fully understand a topic or issue. Those who conduct mixed methods research acknowledge the importance of pursuing both qualitative and quantitative research to achieve more complete results. However, this is not simply an issue of collecting more data just for its own sake. Mixed methods design is purposeful in carefully crafting research questions and employing appropriate research methods to essentially fill in the gaps of knowledge surrounding a particular research inquiry. To determine which methods and data can address particular research needs, let's look at the capabilities of and differences between qualitative and quantitative data collection.Qualitative and quantitative data
Researchers are often quick to make conclusions about whether qualitative research is better than quantitative research or vice versa. The reality is that quantitative and qualitative data can both look at the world in different ways that are useful at various points of a research inquiry. Qualitative and quantitative research are established research paradigms precisely because they provide relevant insights with the appropriate research design, data collection, and analysis. One of the main goals of qualitative research is to generate a description of a social phenomenon. When something is difficult to quantify, it needs to be broken down into more constituent elements that are, by themselves, easier to perceive. In educational evaluation, for example, it is difficult to evaluate good academic writing with just a single score alone. Writing teachers employ a rubric to measure writing by a number of aspects which may include argumentation, organization, and cohesion. Qualitative methods of research tend to collect data for an analysis that is capable of generating frameworks of constituent elements. Such a framework can then be used in subsequent research, evaluation, or decision-making processes. Researchers can collect qualitative data from observations, interviews, or records searches. Qualitative data analysis then aims to identify patterns and themes frequently appearing in the collected data. The efficacy of experimental drugs in clinical trials, for example, is seldom easy to measure through quantitative methods alone. Qualitative research methods are often employed to determine a research participant's well-being, emotional state of mind, and other factors to help researchers decide the overall success of their clinical trials.Quantitative research
If qualitative methods describe a concept or phenomenon, quantitative methods employ the resulting framework to measure that concept or phenomenon. Quantitative research methodology takes the theories generated from qualitative findings to collect quantitative data that can be used to measure a concept or phenomenon at scale. Ultimately, numbers and values inform decision-making processes in many contexts. Quantitative results are useful in research areas where precision is valued or required. Still, they are also used in social and behavioral research to numerically describe phenomena that may not appear to be naturally quantifiable.Mixing methods
Quantitative and qualitative strands of research are often pitted against each other for various reasons. Researchers might shun qualitative data collection as it is often time-consuming. In contrast, quantitative data collection is often critiqued for its reductive power (i.e., reducing ambiguous concepts into simplistic numerical values). Many scholarly disciplines, as a result, tend to prefer one research paradigm over the other (e.g., chemistry tends toward quantitative data collection, while anthropology tends toward qualitative data collection). In the long run of any sufficiently complex research inquiry, however, it is seldom necessary to remain confined to one research approach. The main objective of scientific research is to organize knowledge through theories about the world around us. As a result, researchers employ mixed methods to combine theory generation in qualitative research with confirmatory testing in quantitative research to ultimately produce a robust theory and new knowledge. However, research studies that combine qualitative and quantitative methods for the sake of having multiple methods of data collection and analysis are not as persuasive or impactful as true mixed methods studies where research methods are purposefully chosen to achieve a better understanding.An example of mixed methods research
The objective of mixed methods research designs is to employ different inquiry components under one larger study. However, it might be easier to think of mixed methods research designs as having at least one qualitative study and one quantitative study, each with related but ultimately separate research questions. Examining a mixed methods research design in this way might make it easier to understand the need for pursuing multiple methods in certain cases.- Consider the following example:

As a result, one possible mixed methods study might look at the performance metrics of the company. Research question 1 (RQ1) is posed to conduct a quantitative research study that collects data on possibly quantifiable concepts related to work (e.g., amount of sales generated, number of new clients acquired). In this case, the researchers collect quantitative data to compare post-remote work performance to pre-remote work performance and determine if productivity has changed over time.
While this is a useful angle to examine remote work, it does not tell the whole story. After all, if people at Company XYZ are more or less productive than before, what are the reasons that explain this change? To address research question 2 (RQ2), researchers collect qualitative data on the level of satisfaction employees have with their jobs. Qualitative data from interviews with employees can be used to determine which aspects of their job they find satisfying or not.
With all the data collected, mixed methods researchers can combine the initial quantitative results and the initial qualitative results to form a deeper understanding of their topic of inquiry. In this case, if the quantitative data shows that worker productivity has suffered since the switch to remote work, the qualitative data might illuminate the aspects of remote work that employees don't like.
