Introduction to Quantitative Research
Chapter 4: Latest Update Graded A+
What does standard deviation measure in a dataset?
✔✔ The spread or variability of the data around the mean.
What is the mean in quantitative research?
✔✔ The average value of a dataset.
Why are scatterplots used in quantitative research?
✔✔ To visualize the relationship between two variables.
What is the main advantage of quantitative research?
✔✔ Its ability to produce replicable and generalizable results.
What is the significance of operational definitions?
✔✔ They clarify how variables are measured and ensure consistency.
1
,What is the primary goal of an experimental design in quantitative research?
✔✔ To establish cause-and-effect relationships.
What does correlation measure in quantitative research?
✔✔ The strength and direction of the relationship between two variables.
What is the function of a research question in quantitative research?
✔✔ To define the focus and purpose of the study.
How does quantitative research differ from qualitative research?
✔✔ Quantitative research focuses on numerical data, while qualitative research explores
subjective experiences.
Why are ethical considerations important in quantitative research?
✔✔ To protect the rights and well-being of participants.
What is the role of a hypothesis test in quantitative research?
✔✔ To determine whether the observed results support the hypothesis.
2
, Why is objectivity important in quantitative research?
✔✔ To ensure the results are unbiased and reliable.
What type of data is used in quantitative research?
✔✔ Numerical data.
What is the role of statistical analysis in quantitative research?
✔✔ To interpret data and test hypotheses.
How are variables typically defined in quantitative research?
✔✔ Through operational definitions that specify how they are measured.
What is the purpose of using a large sample size in quantitative research?
✔✔ To improve the reliability and generalizability of the findings.
What is the goal of a hypothesis in quantitative research?
✔✔ To make a testable prediction about the relationship between variables.
