Discuss the differences and similarities between quantitative, qualitative and mix methods research studies.

ANSWER
Quantitative, qualitative, and mixed methods research studies are all distinct approaches to research, but they also share some similarities.

Quantitative research focuses on collecting and analyzing numerical data to answer research questions. It is often used to test hypotheses, establish relationships between variables, and make generalizations about a population. Quantitative research methods include surveys, experiments, and content analysis.

Qualitative research focuses on collecting and analyzing non-numerical data, such as interviews, focus groups, and observations. It is often used to explore complex social phenomena, understand people’s experiences, and develop new theories.

Mixed methods research combines quantitative and qualitative research methods to provide a more comprehensive understanding of a research question. It can be used to explore complex phenomena from multiple perspectives, to validate findings from one method with another, or to expand on the findings of one method with another.

Differences between quantitative, qualitative, and mixed methods research studies:

Characteristic Quantitative Research Qualitative Research Mixed Methods Research
Data type Numerical Non-numerical Both numerical and non-numerical
Purpose Test hypotheses, establish relationships between variables, make generalizations Explore complex social phenomena, understand people’s experiences, develop new theories Provide a more comprehensive understanding of a research question
Methods Surveys, experiments, content analysis Interviews, focus groups, observations Combination of quantitative and qualitative methods
Similarities between quantitative, qualitative, and mixed methods research studies:

Characteristic Quantitative Research Qualitative Research Mixed Methods Research
Goal To produce knowledge that advances understanding of a particular phenomenon
Systematic Yes Yes Yes
Rigorous Yes Yes Yes
Ethical Yes Yes Yes
Examples of quantitative, qualitative, and mixed methods research studies:

Type of Research Example
Quantitative A study to determine the effectiveness of a new drug in treating a particular disease.
Qualitative A study to explore the experiences of people living with HIV/AIDS.
Mixed methods A study to investigate the factors that contribute to student success in college.
Researchers choose the research approach that is most appropriate for their research question and goals. Quantitative research is often used to answer questions about cause and effect, while qualitative research is often used to answer questions about people’s experiences and perspectives. Mixed methods research can be used to answer a variety of questions, but it is particularly useful for complex questions that require a more comprehensive understanding.
