Mixed Methods Research: Overview of Designs and Techniques

Mixed methods research is becoming more common because it helps you examine a research question entirely. You can answer complex questions that require one method alone, such as learning to use qualitative and quantitative data.

You can gather and analyze both kinds of data in this study style. This allows you to benefit from the strengths of each method, which can give you a broader view and reveal deeper connections in the research.

For instance, if you’re researching trends in healthcare, a mixed methods approach can help you understand the overall patterns with quantitative data while also exploring individual experiences through qualitative data. This approach is especially helpful when dealing with complex issues where different perspectives are needed for a full understanding.

In this blog, we will explore the advantages and disadvantages of mixed methods research and discuss how combining qualitative and quantitative approaches can provide a more complete understanding of complex topics.

What is Mixed Methods Research?

Mixed methods research combines qualitative and quantitative research methods to give a more complete view of a research question. It uses both approaches to gain a deeper understanding of the topic.

• Quantitative research gathers numerical data through surveys, experiments, or other methods that produce measurable results, like ages or percentages. It helps identify patterns, test theories, and make general conclusions.
• Qualitative research collects non-numerical data to explore beliefs, motivations, attitudes, and experiences through interviews and focus groups. It provides detailed insights and helps understand the reasons behind numerical trends.

Combining both data types gives you a fuller picture of the research question. This approach is especially useful in behavioral, health, and social sciences, where understanding complex issues requires multiple perspectives.

Mixed methods research is valuable for situations where statistical data and personal insights are needed. It offers a richer and more nuanced understanding of the problem.

When to Use Mixed Methods Research?

Mixed methods research is a good choice when using only quantitative or qualitative data, which won’t fully answer your research question. Combining both data types can give you a more complete picture of your research problem.

Common reasons for using mixed methods:

1. Generalizability: Qualitative research typically involves smaller groups, so applying the findings widely is hard. Including quantitative data, which comes from larger groups, helps make more general conclusions.
2. Contextualization: Quantitative data shows patterns, but qualitative data, like interviews, helps explain why these patterns exist.
3. Credibility: Using both methods to study the same issue makes the results more reliable. When both sets of data agree, it boosts confidence in the findings.

For example, if you’re surveying consumer preferences, you could gather quantitative data such as how many people prefer each product and their demographics. However, by also collecting qualitative data through interviews or focus groups, you can explore why people have certain preferences. It can give you deeper insights.

Use mixed methods research when a single approach doesn’t fully answer your research question. But remember, it’s not just about collecting both types of data; you also need to combine them to create coherent, meaningful conclusions.

Types of Mixed Methods Research Designs

Mixed methods research can be challenging, but knowing the different designs can help you pick the right one for your study. There are four main types of mixed-method research: convergent parallel, embedded, explanatory sequential, and exploratory sequential. Each design differs in how you collect and combine data.

Convergent Parallel Design

In this design, you collect both quantitative and qualitative data simultaneously but analyze them separately. This allows you to compare results and see if they support each other.

For example, you could survey how patients feel about hospital services and conduct in-depth interviews with some of them. This would give you a more complete understanding of their experiences.

Embedded Design

Here, both data types are collected simultaneously, but one is more important than the other. Usually, the main focus is on the numbers, while qualitative data provides extra details.

For example, you could survey students’ school performance and interview teachers to explain the results. The teachers’ feedback (qualitative data) adds depth to the numbers.

Explanatory Sequential Design

In this approach, you start by collecting quantitative data and then follow up with qualitative data to better understand the results. This is useful when numbers alone don’t tell the whole story.

For example, measure the effectiveness of a fitness program by tracking weight loss and interviewing participants to learn about their experiences and challenges with it.

Exploratory Sequential Design

This design starts with qualitative data to explore a topic, followed by quantitative data to measure or test what you’ve found. It’s helpful when you’re studying something new and want to gather information before doing structured research.

For example, you could begin by having focus group discussions with factory workers about their working conditions. After identifying key issues, you could create a survey to find out how widespread these concerns are among a larger group of workers.

Sampling Method for Mixed Methods Research

Selecting the proper sampling method is essential in mixed methods research because it affects the quality and usefulness of the data collected. The most suitable method depends on the research goals and the type of study being conducted. Below are some of the commonly used sampling methods in mixed methods study.

Snowball Sampling

In snowball sampling, you start with a few participants who then suggest other people for the study. This approach is especially helpful when trying to reach specific groups or people who are difficult to reach.

• Useful for studying hidden or hard-to-reach groups.
• It can create a network of participants with shared traits or experiences.
• However, it might lead to bias if the initial participants have similar views or backgrounds.

Convenience Sampling

Convenience sampling involves choosing participants who are easy to reach and nearby. This method is often used when there is limited time, resources, or access to participants.

• It’s simple and cost-effective.
• It is fast and easy to use, especially when resources are tight.

Purposive Sampling

Purposive sampling, also called judgmental or selective sampling, involves choosing participants who fit specific criteria essential to the research. This ensures the participants have the right experience or knowledge for the study.

• Allows for targeted data collection from participants with relevant experience.
• It can provide detailed insights into specific parts of the research topic.
• This may lead to bias since the sample isn’t randomly selected.

Techniques for Integrating Quantitative and Qualitative Data

Integrating quantitative and qualitative data in mixed methods research is essential for fully understanding complex research topics. Below are some useful ways to integrate these two types of data:

Mixed Methods Research Question

When working with mixed methods research, your question should combine qualitative and quantitative methods to get a full picture of a complex issue. Here’s how to approach it:

What Makes a Good Mixed Methods Question?

Your question should include both numbers and deeper insights. For instance, measure something with stats and explore people’s experiences or opinions. It should tackle a complex issue that requires more than numbers or stories to understand fully.

Ensure your question lets you combine findings from both data types to get a well-rounded view.

You should use mixed methods when:

• Your question needs both numerical data and personal insights.
• You need to combine different types of data to understand the issue fully.
• You want to validate and expand on your findings with both kinds of data.

How to Formulate Your Question?

First, you need to define the problem you want to study. Take the time to identify the complex issue you’re interested in, and ensure it requires qualitative and quantitative data. This step is crucial as it lays the foundation for your research approach.

Next, set your objectives. Consider what specific aspects of the problem you need to measure and which areas you want to explore more deeply. This might involve outlining the key variables you want to quantify and the contextual factors you wish to understand better. By setting clear objectives, you can focus your research and gather relevant data that addresses your core research questions.

Finally, craft your question carefully. Formulate a question that integrates both the measurable aspects and the deeper context of the problem. Your question should be broad enough to cover the qualitative insights you need and specific enough to gather quantifiable data.

A well-rounded question will help you gather comprehensive information and provide a clearer understanding of the issue at hand.

Examples of Mixed Methods Question

If you’re researching leadership practices, here are some examples of mixed methods questions you can use:

Q1. What leadership practices do successful headteachers use, and how do these practices affect school performance?”

• Quantitative: To measure types and impacts.
• Qualitative: To explore details of these practices.

Q2. Are there common practices among successful headteachers, and how do headteachers and their subordinates view these practices?

• Quantitative: To find common practices.
• Qualitative: To understand different perspectives.

Q3. How do opinions about leadership practices differ between headteachers and their subordinates, and why?

• Quantitative: To compare opinions.
• Qualitative: To explore reasons for differences.

Mixed methods help you get a richer and more complete understanding of complex issues by combining the strengths of both quantitative and qualitative approaches.

Advantages of Mixed Methods Research

Mixed methods research combines the strengths of both qualitative and quantitative data, which can help you get a more complete view of whatever you’re studying. By integrating both types of data, you can gain deeper insights and validate your findings more effectively than using one method alone.

01. A More Complete Picture

One of the significant advantages of mixed methods is that it lets you explore a topic from different angles.

For example, suppose you’re looking at how exercise affects mental health. In that case, you can start with surveys to measure physical activity levels and quantitative data on mental health across a group of people. Follow up with interviews to hear their personal experiences and get more detailed stories, which are qualitative data.

This combination will give you a clearer and complete understanding of the issue.

02. Resolving Conflicting Results

Mixed methods can also help when you get conflicting results.

For example, if your survey data shows one thing, but your interviews tell a different story, combining both data types can help you determine why the results don’t match.

Combining both methods allows you to investigate these differences and uncover their reasons.

03. Combining Strengths

Another great advantage of mixed methods is that it balances out the weaknesses of each approach:

• Qualitative data gives you rich, detailed insights into people’s experiences.
• Quantitative data gives you broad, general results that apply to larger groups.

When you use both, you can create a more reliable and well-rounded understanding.

For example, more than qualitative research is required, but adding quantitative data can help confirm the findings. Similarly, quantitative data might need to include personal details that qualitative research can capture.

04. Flexibility in Design

Mixed methods research also gives you more flexibility in your research design. You’re not locked into one approach or research style. This means you can:

• Test theories and build new ideas within the same study.
• Adjust your research design as needed to include both types of data.

Disadvantages of Mixed Methods Research

While mixed methods research offers many benefits, it also comes with challenges that make it more difficult to manage than quantitative or qualitative methods.

• Increased time and effort: Collecting, analyzing, and integrating qualitative and quantitative data requires significantly more time and effort than using a single method.
• Need for collaboration: Mixed methods research often requires a team of researchers from various fields, increasing the project’s complexity.
• Higher costs: The approach tends to be more expensive due to the need for additional resources, time, and personnel.
• Possibility of conflicting results: Qualitative and quantitative data might only sometimes align, potentially leading to contradictory findings.
• Challenges in interpretation: Conflicting findings, such as differences between survey and interview results, make it harder to interpret the data.
• Balancing data types: Careful thought is required to balance broad numerical data with detailed, subjective insights, avoiding bias in conclusions.
