UNIT 2 The Qualitative and Quantitative Research Alcala, Cabañas, Cabangcalan, Lanete, Tagapoli, Villanueva At the end of the unit the students must have: 1. defined the importance and purpose of qualitative and quantitative research. 2. differentiated the qualitative and qualitative research. 3. analyzed qualitative and quantitative data.  01 What is Qualitative and Quantitative Research?  Qualitative Research These methods are exploratory and are used to understand perceptions, behaviors, or experiences. They rely on words, visuals, or observations rather than numbers. Focuses on exploring phenomena, understanding experiences, and interpreting meanings through non-numeric data such as interviews, observations, and textual analysis. Examples: Understanding customer satisfaction, exploring cultural practices, or identifying social challenges.  Quantitative Research These methods use numerical data to measure and analyze variables. They aim for objectivity and generalizability by using statistical tools to test hypotheses. Examples: Measuring the impact of marketing strategies, analyzing trends, or testing scientific theories.  02 Why Qualitative and Quantitative Research Matters?  Qualitative Research Uncovers human experiences Qualitative research can help 1 researchers understand how people feel about their experiences, and what motivates them. 2 Identifies intangible factors Qualitative research can help identify 3 factors like socioeconomic status, ethnicity, and gender roles.  Qualitative Research Uncovers human experiences Qualitative research can help 1 researchers understand how people feel about their experiences, and what motivates them. Helps inform healthcare Qualitative research can help healthcare professionals understand how patients feel about their health, and how to tailor care to their needs. Qualitative Research Helps understand complex issues Qualitative research can help researchers 1 understand the "how" and "why" of complex issues, such as how COVID-19 spread through different populations 2 3  Quantitative Research Objective data Quantitative research produces data that 1 is free from bias and subjectivity. This allows researchers to make more accurate and impartial conclusion. 2 Reliable data Quantitative research uses standardized procedures and large sample sizes to ensure that findings can be replicated 3 and trusted.  Quantitative Research Insights Quantitative research can provide 1 insights about trends and patterns, which can help people understand complex problems. 2 Evidence-based decisions Quantitative research can help people make evidence-based decisions in areas like 3 healthcare, education, and busines Quantitative Research Advance knowledge Quantitative research can help 1 advance knowledge by contributing to the body of research in a given field. 2 3 Purpose of Qualitative and Quantitative Research 03  Objective/Purpose To gain an understanding of underlying reasons and motivations. Qualitative To uncover prevalent trends in thought and opinion To quantify data and generalise results from a sample to the population of interest To measure the incidence of Quantitative various views and opinions in a chosen sample. 04 Qualitative and Quantitative Research Methods  Data Collection Data collection is the process of gathering information to solve a problem or answer a research question. Qualitative Quantitative Methods: Interviews, focus Methods: Surveys, groups, participant experiments, structured observation, document observations, probability analysis, and open-ended samples, interview, and surveys. secondary data analysis. Tools: Audio/video Tools: Questionnaires, recordings, transcription measuring instruments, online software, field notes. data collection  Data Analysis Data analysis is the practice of working with data to glean useful information, which can then be used to make informed decisions. Qualitative Quantitative Grounded theory Descriptive statistics Content analysis Inferential Statistics Narrative analysis Regression Analysis Discourse analysis Thematic analysis: 05 Combining Qualitative and Quantitative Approaches (Mixed Methods)  Mixed Methods A research design that integrates both qualitative and quantitative methods to provide a more comprehensive understanding of a research problem. Purpose: To triangulate data for stronger validity. To balance in-depth insights with measurable outcomes. Example: Conducting interviews (qualitative) to understand customer feedback and using surveys (quantitative) to measure satisfaction levels.  06 Summary  Summary Aspects Qualitative Quantitative Non-numerical, (text, Numerical (statistics, Nature of Data images, video). numbers).
