Introduction to Quantitative Research
Questions and Answers Graded A+
How do researchers test their hypotheses in quantitative research?
✔✔By collecting and analyzing numerical data
What ensures consistency in data collection across participants?
✔✔Using standardized tools and procedures
What is the role of statistical significance in quantitative research?
✔✔To determine if the results are likely due to chance or actual effects
Why is replication critical in quantitative research?
✔✔It strengthens the reliability and validity of findings
What is the purpose of using charts and graphs in quantitative research?
✔✔To visually summarize and present data
1
,How is bias minimized in quantitative data analysis?
✔✔By employing objective statistical methods
What does it mean when a study has high internal validity?
✔✔The study accurately measures the effect of the independent variable on the dependent
variable
How do researchers increase the reliability of their measurements?
✔✔By using well-tested and validated measurement tools
Why are control groups essential in experimental designs?
✔✔They help isolate the effects of the independent variable
What is a confounding variable?
✔✔A factor that influences the dependent variable but is not the focus of the study
How is causation established in a quantitative study?
✔✔Through experimental design with controlled manipulation of variables
2
,What is the importance of a clear research question in a study?
✔✔It guides the focus and scope of the research
How do researchers deal with missing data in quantitative studies?
✔✔By using statistical techniques like imputation or exclusion
What does the term "sample population" mean in quantitative research?
✔✔A subset of the population selected for the study
How do researchers select a representative sample?
✔✔By using random sampling methods
What is the importance of hypothesis testing in quantitative research?
✔✔It helps confirm or refute predictions based on data
How is reliability measured in quantitative research tools?
✔✔By assessing consistency across repeated measurements
3
, What is the role of an operational definition in a study?
✔✔To specify how variables will be measured or defined
Why are ethical considerations crucial in quantitative research?
✔✔To protect participant rights and ensure the integrity of the research
What is the difference between primary and secondary data in quantitative research?
✔✔Primary data is collected directly by the researcher, while secondary data is pre-existing
What is the purpose of inferential statistics in research?
✔✔To make generalizations about a population based on sample data
Why do researchers use confidence intervals?
✔✔To estimate the range within which the true population parameter lies
What is the benefit of using random assignment in experiments?
✔✔It ensures that groups are comparable, reducing bias
