Quantitative Research Methods

Questions and Answers

What is a key feature of quantitative research that allows for generalization to the whole population?

It involves subjective interpretations of data.

It is conducted on a large sample of the population. (correct)

It relies heavily on qualitative feedback.

It focuses exclusively on case studies.

Why can decisions be made for the entire population based on the outcome of quantitative research?

Quantitative research includes in-depth interviews.

The sample population is always small and controlled.

It often relies on anecdotal evidence.

The findings are derived from a large and representative sample. (correct)

Which statement best describes the relationship between sample size and the outcomes of quantitative research?

Smaller sample sizes provide better reliability.

Larger sample sizes make generalization easier. (correct)

Sample size has no impact on decision-making.

Study Notes

Generalization in Quantitative Research

Quantitative research outcomes can be generalized to the entire population.
Conducted on a large sample size, enhancing the reliability of results.
Findings from the sample allow for informed decisions impacting the whole population.
Statistical methods used in quantitative research support broader applicability of results.
Enables identification of trends and patterns that reflect the larger group.

Kinds of Quantitative Research

Comparative Research
- Focuses on comparing two or more groups of study subjects.
- Examines differences based on a specific dependent variable.
Correlational Research
- Aims to discover relationships between two or more variables.
- Often involves measuring the strength and direction of these relationships.
Experimental Research
- Employs various techniques to manipulate treatment conditions.
- Evaluates the effects of these treatments on participants.
- Considered the most conclusive research design due to its ability to control extraneous factors and establish cause-and-effect relationships.
