What is quantitative research?

• Quantitative research emphasizes subjective interpretations of data.

• Quantitative research is primarily concerned with case studies and personal narratives.

• Qualitative research focuses on understanding human behavior through interviews.

• Quantitative research is a method of inquiry that focuses on quantifying data and analyzing it statistically.

Name one key characteristic of quantitative research designs.

• Focus on subjective experiences.

• Use of numerical data and statistical analysis.

• Analysis of case studies.

• Emphasis on qualitative interviews.

What type of data is primarily used in quantitative research?

• Numerical data

• Categorical data

• Textual data

• Qualitative data

Describe the difference between descriptive and inferential statistics.

• Descriptive statistics analyze relationships between variables, while inferential statistics focus on individual data points.

• Descriptive statistics summarize data, while inferential statistics make predictions about a population based on a sample.

• Descriptive statistics are used for hypothesis testing, while inferential statistics are used for data visualization.

• Descriptive statistics predict future trends, while inferential statistics summarize data.

What is a hypothesis in the context of quantitative research?

• A hypothesis is a testable prediction about the relationship between variables.

• A hypothesis is a definitive conclusion about the variables.

• A hypothesis is a summary of the research findings.

• A hypothesis is an untestable statement about the research topic.

List one advantage of using quantitative research methods.

• Focuses solely on qualitative data without numerical analysis.

• Emphasizes emotional responses over statistical evidence.

• Offers subjective insights based on personal experiences.

• Provides objective and quantifiable data for analysis.

What is the purpose of a control group in an experiment?

• To eliminate all variables in the experiment.

• To provide the experimental group with additional resources.

• The purpose of a control group is to provide a baseline for comparison in an experiment.

• To ensure the experiment is conducted in a controlled environment.

Explain the term 'random sampling' in quantitative research.

• Random sampling involves choosing individuals based on their availability rather than chance.

• Random sampling is a technique that guarantees the selection of the most qualified individuals.

• Random sampling is a method of selecting individuals from a population where each has an equal chance of being chosen.

• Random sampling is a method where only a specific group of individuals is selected based on predetermined criteria.

What is the significance of a large sample size in quantitative studies?

• A large sample size guarantees accurate results regardless of methodology.

• A large sample size decreases the variability of results.

• A large sample size is only important for qualitative studies.

• A large sample size improves the accuracy and reliability of study results.

Identify one common quantitative research design and briefly describe it.

• Experimental design

• Longitudinal design

• Case study design

• Survey design
