01. Meeting 01 - Quantitative Research

What is the primary focus of quantitative research?

• Qualitative data

• Numerical data

• Subjective analysis

• Theoretical frameworks

Answer explanation

The primary focus of quantitative research is on numerical data, which allows for statistical analysis and objective measurement, distinguishing it from qualitative data and subjective analysis.

Which of the following is a key characteristic of quantitative research?

• Exploratory analysis

• Use of structured methods

• Focus on personal experiences

• Emphasis on narrative data

Answer explanation

A key characteristic of quantitative research is the use of structured methods, which allows for systematic data collection and analysis, contrasting with exploratory or narrative approaches that focus on personal experiences.

What type of reasoning does quantitative research primarily use?

• Inductive reasoning

• Abductive reasoning

• Deductive reasoning

• Intuitive reasoning

Answer explanation

Quantitative research primarily uses deductive reasoning, which involves testing hypotheses derived from existing theories. This approach allows researchers to confirm or refute these theories through empirical data.

What is a limitation of quantitative research?

• Statistical power

• Objective measurements

• Lack of depth

• High replicability

Answer explanation

A limitation of quantitative research is its lack of depth. While it provides statistical data, it often fails to explore the underlying reasons or motivations behind the numbers, limiting the understanding of complex phenomena.

Which of the following is an example of a dependent variable?

• Teaching methods

• Questionnaires

• Test scores

• Interventions

Answer explanation

Test scores are the dependent variable as they are influenced by other factors, such as teaching methods or interventions. The other options are independent variables or tools used to measure outcomes.

What does validity refer to in quantitative research?

• Statistical power

• Sample size

• Accuracy of measurement

• Consistency of results

Answer explanation

Validity in quantitative research refers to the accuracy of measurement, ensuring that the tools and methods used truly capture what they intend to measure. This is crucial for reliable results.

Which method involves manipulating variables to observe effects?

• Survey research

• Descriptive statistics

• Quasi-experimental studies

• Experimental research

Answer explanation

Experimental research involves manipulating variables to observe their effects, making it the correct choice. In contrast, survey research and descriptive statistics do not involve such manipulation.

What is the purpose of statistical analysis in quantitative research?

• To collect qualitative data

• To interpret numerical data

• To create narratives

• To explore personal biases

Answer explanation

The purpose of statistical analysis in quantitative research is to interpret numerical data, allowing researchers to draw meaningful conclusions and insights from their findings.

What is a common data collection strategy in quantitative research?

• Interviews

• Focus groups

• Surveys

• Case studies

Answer explanation

Surveys are a common data collection strategy in quantitative research as they allow researchers to gather numerical data from a large sample efficiently, enabling statistical analysis and generalization of results.

What does replicability in research mean?

• The ability to manipulate variables

• The ability to analyze qualitative data

• The ability to repeat the study with the same methods

• The ability to produce different results

Answer explanation

Replicability in research refers to the ability to repeat the study using the same methods and obtain similar results. This ensures the reliability and validity of the findings, making the correct choice "The ability to repeat the study with the same methods."
