1. Qualitative research is a methodology focused on the collection and analysis of non-numerical data, such as words, images, and observations, to understand human behavior, experiences, and social realities.

Some characteristics are:

Naturalistic setting

• Subjective interpretation

• Socially constructed reality

• Complex variables

• Deep exploration

• Flexible design

Common Instruments Used:

Interviews, Focus Groups, Participant Observation, Field Notes, Diaries and Journals, Document and Text Analysis, Audio/Video Recordings

Some principles are: Interpretivism, Inductivism, Contextualization, Reflexivity, Holism.

2. Quantitative research is the science of measuring and analyzing numerical data to uncover patterns, test hypotheses, and make predictions.

Some characteristics: objective measurement, structured design, large Sample sizes, replicability, hypothesis testing, and statistical rigor.

Instruments used: Experiments, structured observations, tests and assessments, secondary data sources, and rating scales and likert scales.

Principles: Positivism, deductive, reasoning, empiricism, generalizability, validity and reliability, statistical significance.

3. Mixed methods research combines quantitative data (numbers, statistics) and qualitative data (words, meanings) within a single study or across related studies. The goal is to integrate both types of data to provide a more complete understanding than either method could offer alone.

Characteristics:

Integration of Methods: Combines qualitative and quantitative approaches intentionally.

• Complementarity: Uses the strengths of one method to offset the limitations of the other.

• Sequential or Concurrent Design: Data can be collected in phases or simultaneously.

• Triangulation: Cross-validates findings by comparing results from both methods.

• Complexity-Friendly: Ideal for studying multifaceted issues like social behavior, health outcomes, or education reform.

Instrument used:

Quantitative Instruments:

• Surveys with closed-ended questions

• Structured observations

• Experiments

• Statistical databases

Qualitative Instruments:

• Interviews (semi-structured or open-ended)

• Focus groups

• Field notes

• Document analysis

Principles: Pragmatism, complementarity, integration, validity through Triangulation, purpose-driven design.

4. In applied linguistics, qualitative research is most commonly used. Applied linguistics often addresses language in real-world contexts, such as learning, teaching, translation, and sociolinguistic interaction. These areas require an understanding of how people use and experience language. Therefore, the most widely used method for this research is qualitative.

1. Qualitative Research

What it is: Studies people’s experiences, opinions, and situations using words, not numbers.

Characteristics: Small groups, detailed descriptions, flexible, focuses on meaning.

Tools: Interviews, observations, focus groups, text analysis.

Principles: Subjective, context matters, looks for themes and patterns.

2. Quantitative Research

What it is: Studies measurable things using numbers and statistics.

Characteristics: Large samples, structured, objective, results shown in graphs or tables.

Tools: Surveys, tests, experiments, statistical software.

Principles: Objective, variables must be measurable, tests hypotheses.

3. Mixed Methods Research

What it is: Combines words and numbers to understand a topic better.

Characteristics: Uses both depth (qualitative) and breadth (quantitative).

Tools: Mix of surveys + interviews, tests + observations, etc.

Principles: Combines strengths of both, practical, gives a fuller picture.

4. In Applied Linguistics

Most used: Qualitative and Mixed Methods.

Why: Because language learning and teaching are complex. Researchers need both numbers (like test results) and personal insights (like student attitudes or teacher strategies).

1. What is cuantitative research?

Quantitative research is a type of study that uses numbers to understand and explain information.

Characteristics: Its main characteristics are being clear, exact, and objective. Its requires mathematical anf statistical knowledge.

The instruments: In a cuantitative research the instruments used are surveys, questionnaires, tests, and experiments, which help gather in a structured way.

The principles: include, control, repetition and validity, it helps find patterns, test ideas, and make conclusions based on evidence.

2. What is a qualitative research?

Qualitative research explores ideas, experiences, felings and meanings using words instead of numbers, it helps researchers understand “why” and “how” things happen through people’s experiences and opinions.

Characteristics: Its main characteristics are that it is subjective, descriptive, flexible, and seeks to understand people’s perspectives in depth.

The instruments: include interviews, observations, focus groups, open-ended questionnaires, and document analysis.

The principles:

Understand people’s feelings, ideas, and experiences

Study in real-life settings

Results are explained with words and stories, not numbers.

3. What is mixed method?

Mixed methods research is a type of study that combines both, quantitative and qualitative research.

Its main characteristics are integration of numerical and descriptive data, flexibility, and complementarity

The instruments: include surveys, tests, interviews, focus groups, and observations.

Its main principles include integration (combining both types of data), complementarity (each method adds unique insights), triangulation (cross-checking results for accuracy), development (one method helps guide the other), expansion (exploring different aspects of the topic), and pragmatism (using the best methods to answer the research question). Together, these principles help researchers produce more complete and reliable results.

4. What is the type of research mostly used?

in Applied Linguistics the most common is qualitative research.

Why? because it focuses on understanding how learners experience language, how they interact in real situations, and how teachers and students give meaning to language practices.

# data[].attributes.body

Characteristics: integration of methods, complementarity, triangulation.

Instruments Used: trials, statistical datasets, documents analysis, mix os surveys.

Principles: integration, contextualization and flexibility.

What is the type of research mostly used in Applied Linguistics and why?

Applied linguistics explores how language is learned, taught, and used in real world contexts. That means researchers often need to understand deep, contextual, and human centered phenomena like how learners feel about language, how teachers adapt instruction, or how culture influences communication. These are areas where qualitative methods shine.

1. What is qualitative research?

Qualitative research is used to deeply explore people´s experiences, thoughts, and social contexts. It´s a subjective and flexible approach that focuses on understanding meaning rather than producing numbers. What makes it unique is its context based and exploratory nature, which allows researchers to adapt as the study unfolds. To gather this kind of in depth information, qualitative research uses tools like interviews, focus groups, observations, open ended questionnaires, and document analysis. Its main principles include giving voice to participants, interpreting behavior within context, and aiming for deep insights rather than broad generalizations.

2. What is quantitative research?

Quantitative research, on the other hand, is all about measuring and analyzing data in numerical form. I came to understand that it´s objective, structured, and based on large samples, which makes it ideal for testing hypotheses and identifying patterns. The tools it relies on include surveys with closed questions, standardized tests, experiments, and various statistical analysis software. Its principles focus on ensuring reliability, validity, and replicability, and it often seeks to establish cause and effect relationships. It’s a more controlled method, often used when the goal is to generalize findings to larger populations.

3. What is mixed method research?

Mixed methods research combines both qualitative and quantitative strategies. This approach is especially helpful when a single method doesn’t fully address the research question. It’s integrative, complementary, and allows for flexibility in how the study is designed and conducted. Researchers using mixed methods might combine interviews, surveys, tests, focus groups, and observations to collect a fuller picture of the issue. Key principles include triangulation, where multiple data sources are used to increase validity, complementarity, where one method strengthens the other, and practicality, meaning the focus is on what best answers the research question.

4. What type of research is mostly used in Applied Linguistics and why?

In Applied Linguistics, I´ve learned that qualitative research is most commonly used, often combined with mixed methods. This is because the field explores how people learn and use language in real life situations something that requires deep, descriptive insights rather than just numerical data. For example, studying classroom interaction or language acquisition involves understanding context, behavior, and personal experience, which aligns closely with the principles and tools of qualitative research. While quantitative data can support these findings, the richness of qualitative data is essential to fully grasp how language functions in practice.

# data[].attributes.body
Quantitative research is about numbers, measurement, and statistical analysis. It seeks to answer questions like “how much,” “how often,” or “what is the measurable difference”. It uses structured tools such as surveys, experiments, and numerical datasets to produce results that can often be generalized to larger populations. Its strength lies in precision and comparability, but it may overlook the deeper context or meaning behind the data.

Qualitative research focuses on words, meanings, and lived experiences. It explores the “why” and “how” of a phenomenon through interviews, observations, and open‑ended responses. It captures rich, detailed insights and the complexity of human behavior, but because it often involves smaller samples and subjective interpretation, its findings are less easily generalized.

Mixed methods research integrates both quantitative and qualitative approaches in a single study. It uses numbers to reveal patterns and stories to explain them, offering a more complete understanding of a topic. This approach is valuable when one method alone would leave important questions unanswered, but it requires careful design to ensure both types of data complement each other meaningfully.

- Evaluate whether the mixed approach adds value compared to a single method.

4- What is the Type of Research Mostly Used in Applied Linguistics and Why?

Qualitative research is commonly used in Applied Linguistics because it often explores subjective topics, such as language use, learner perceptions, or teaching experiences, which are best studied through qualitative methods. It focuses on detailed insights into how people use or learn language, which requires tools like interviews or observations to capture thoughts, feelings, or behaviors.

# data[].attributes.body
1. What is Qualitative Research?
Qualitative research is the type of research that focuses on understanding human experiences, behaviors, and perspectives. It does not rely on numbers, but rather on descriptive data, such as the characteristics and profiles of individuals, communities, and groups.

Characteristics: It is exploratory, subjective, and flexible. It studies phenomena in their natural context and aims to find meaning rather than measure variables.

Instruments used: Interviews, focus groups, observations, field notes, and open-ended questionnaires.

Principles: Emphasis on context, interpretation, and meaning-making. It values participants’ voices and acknowledges the researcher's influence in the process.

2. What is Quantitative Research?
Quantitative research is an approach that investigates phenomena through numerical data and statistical analysis. It seeks to measure, compare, and test relationships among variables.

Characteristics: Objective, structured, and systematic. It uses large samples and aims for reliability and generalization.

Instruments used: Surveys with closed questions, experiments, tests, and statistical tools.

Principles: Standardization, measurement, control of variables, and statistical validation.

3. What is Mixed Method Research?
Mixed-method research combines both qualitative and quantitative approaches in the same study. It allows researchers to explore experiences in depth while also measuring patterns or testing hypotheses.

Characteristics: Integrative, complementary, and pragmatic. It seeks a more complete understanding of a research problem.

Instruments used: A combination of interviews, observations, surveys, tests, and statistical software.

Principles: Triangulation, complementarity, and integration of qualitative and quantitative data to strengthen the validity of results.

4. What is the type of research mostly used in Applied Linguistics, and why?
In Applied Linguistics, qualitative research is mostly used because it helps researchers understand how language is learned, taught, and used in real contexts. Since language involves interaction, meaning, and culture, qualitative methods allow for a deeper exploration of learners’ perspectives, teachers’ practices, and classroom dynamics. However, mixed methods are also increasingly common, as they provide both descriptive insights and measurable evidence.

# data[].attributes.body
1. What is qualitative research? Characteristics, instruments used, and principles.

Qualitative research is a method focused on understanding human experiences, perspectives, and behaviors in their natural setting. Instead of numbers, it uses non-numerical data such as words, images, or observations to explore the "why" and "how" of a phenomenon in depth.

Characteristics:

Naturalistic: It studies phenomena in their real-world context.

Interpretive: The researcher is the key instrument for interpreting the data.

Flexible: The research design can evolve as information is gathered.

Focused on meaning: It seeks to understand the perspectives and meanings that participants attribute to their experiences.

Instruments Used:

Interviews: In-depth conversations that can be structured, semi-structured, or open.

Focus Groups: Group discussions to explore a specific topic.

Observation: The researcher directly observes and records behaviors and interactions.

Document Analysis: Examination of existing texts, diaries, photos, and other materials.

Principles:

Deep Understanding: The goal is to gain a rich and detailed understanding, not to generalize findings.

Inductive: Theories and conclusions emerge directly from the collected data.

Holistic: It considers the phenomenon as a complex and contextualized whole.

2. What is quantitaive research? Characteristics, instruments used, and principles.

Quantitative research focuses on the collection and analysis of numerical data. It uses statistics to measure, test hypotheses, identify patterns, and generalize results from a large sample to an entire population. It seeks to answer questions like "how many?", "how often?", or "to what extent?".

Characteristics:

Numerical: Data is in the form of numbers and is analyzed statistically.

Objective: It aims to eliminate researcher bias through the use of structured tools.

Structured: It follows a linear and predefined process.

Generalizable: Findings from a sample are intended to be applied to a broader population.

Instruments Used:

Surveys and questionnaires: Primarily with closed-ended questions (multiple choice, Likert scales).

Experiments: Variables are manipulated in a controlled environment to establish cause and effect relationships.

Analysis of existing data: Use of pre-existing statistical databases.

Standardized tests: Consistent and objective measurements.

Principles:

Measurement: Quantifying variables and the relationships between them.

Deductive: It starts with a hypothesis or theory and then tests it with data.

Replicability: Other researchers should be able to repeat the study and obtain similar results.

Objectivity: Findings should be based on data, not the researcher's opinions.

3. What is mixed method research? Characteristics, instruments used, and principles.

Mixed methods research is an approach that integrates both qualitative and quantitative research within a single study. The goal is to combine the strengths of both methods to obtain a more complete and comprehensive understanding of the research problem than could be achieved separately.

Characteristics:

Integration: It combines the collection and analysis of numerical and non-numerical data.

Pragmatic: The research question determines the methods to be used, without adhering to a single paradigm.

Complementary: It uses one method to inform, expand upon, or validate the findings of the other.

Instruments Used:

It combines instruments from both approaches. For example, a quantitative survey might be administered, followed by qualitative interviews with a subgroup to explore their responses in greater depth.

Principles:

Triangulation: Using different methods to verify and corroborate findings.

Comprehensive View: Seeking a more complete and multifaceted perspective of the phenomenon.

Flexibility: The design can be sequential (one method after the other) or concurrent (both at the same time).

4. What is the type of research mostly used in Applied Linguistics and why.

Applied Linguistics deals with practical, real world language problems, such as second language acquisition, language teaching, sociolinguistics, or discourse analysis. These topics are deeply tied to social context and human experience aspects that quantitative research alone cannot fully capture.

1. Complexity of Language: Language use is a complex and dynamic social phenomenon. Qualitative methods, like case studies or ethnography, allow researchers to study language in its natural setting and understand nuances that numbers cannot express.

2. Focus on the Individual: There is a great interest in understanding the experiences, beliefs, and strategies of language learners. Interviews and learning diaries (qualitative methods) are ideal for accessing these subjective perspectives.

3. Richness of Context: To understand why a teaching strategy works or not, analyzing the context is crucial. Qualitative research provides rich and detailed descriptions of that context.

4. Comprehensive Solutions: Mixed methods are particularly useful because they can, for example, measure the success of a teaching method with tests (quantitative) while simultaneously explaining why it worked through observations and interviews with students and teachers (qualitative).
