Exploring Research Designs and Measurements

What is a case study in qualitative research?

• A case study is a theoretical framework without real-world application.

• A case study is an in-depth analysis of a specific instance or example within its real-life context.

• A case study is a statistical analysis of large data sets.

• A case study is a brief summary of research findings.

Define phenomenological research design.

• A method that focuses solely on statistical analysis of data.

• A research design that only examines historical events.

• A quantitative approach that measures variables and tests hypotheses.

• Phenomenological research design is a qualitative approach that explores and describes the lived experiences of individuals.

What is grounded theory and its purpose?

• Grounded theory is a method for conducting experiments in a lab.

• Grounded theory focuses solely on quantitative data analysis.

• Grounded theory is a historical research method used to study past events.

• Grounded theory is a research method aimed at generating theories based on data analysis.

Explain the concept of ethnography in research.

• Ethnography is a qualitative research method focused on studying cultures and communities through direct observation and participation.

• Ethnography is a quantitative method for analyzing statistical data.

• Ethnography is primarily focused on laboratory experiments and controlled settings.

• Ethnography involves conducting surveys to gather numerical data.

What distinguishes correlational research from other designs?

• Correlational research requires a control group for comparison.

• Correlational research involves experimental manipulation of variables.

• Correlational research only examines one variable at a time.

• Correlational research focuses on identifying relationships between variables without manipulation.

Describe descriptive research and its applications.

• Descriptive research is used in various fields such as social sciences, market research, and health studies to gather insights about behaviors, attitudes, and characteristics of groups.

• Descriptive research is primarily used for experimental studies.

• Descriptive research focuses solely on numerical data analysis.

• Descriptive research is not applicable in the field of education.

What is the main goal of experimental research?

• To observe phenomena without intervention.

• To test existing theories without manipulation.

• To establish cause-and-effect relationships.

• To gather qualitative data.

How does quasi-experimental research differ from true experiments?

• Quasi-experimental research always uses random assignment.

• Quasi-experimental research is only conducted in laboratory settings.

• True experiments do not involve any control groups.

• Quasi-experimental research differs from true experiments in that it does not use random assignment to groups.

Identify an example of nominal data.

• Temperature readings (e.g., 20°C, 30°C)

• Height of individuals (e.g., 5'6", 6'0")

• Colors of cars (e.g., red, blue, green)

• Types of fruit (e.g., apple, banana)

Provide an example of ordinal data.

• Temperature scale (e.g., Celsius, Fahrenheit)

• Rating scale (e.g., 'poor', 'fair', 'good', 'very good', 'excellent')

• Count of items (e.g., 1, 2, 3)

• Categories (e.g., fruit, vegetable, grain)
