Questions and Answers

What is the primary distinction between survey research and experimental research?

Survey research focuses on describing trends and opinions, while experimental research tests the impact of a treatment on an outcome.

What role does causation play in experimental research?

Causation in experimental research helps establish whether a treatment directly influences an outcome.

Describe the two main types of data analysis techniques used in quantitative research.

The two main types are descriptive analysis, which summarizes data, and inferential analysis, which makes comparisons to establish relationships.

How does descriptive analysis contribute to data interpretation?

Descriptive analysis provides a numerical summary of results, such as frequencies and average scores, which aids in understanding data trends. Signup and view all the answers

What is the purpose of an inferential analysis in survey research?

Survey research is primarily concerned with gathering opinions and trends from a population. Signup and view all the answers

In the context of quantitative research, what does controlling other factors entail?

Controlling other factors in experimental research involves isolating the treatment effect to ensure it is the primary influence on the outcome. Signup and view all the answers

Explain why sampling is important in both survey and experimental research.

Sampling is important as it allows researchers to study a manageable subset of a population, facilitating the analysis of trends or treatment effects. Signup and view all the answers

What distinguishes independent variables from dependent variables in a study?

Study Notes

Nature of Quantitative Research

Two primary types of quantitative research: survey research and experimental research.
Survey research provides a numerical description of trends, attitudes, or opinions within a population.
Experimental research tests the impact of treatments or interventions while controlling extraneous factors.

Survey Research

Utilizes questionnaires as the main data collection tool.
Well-known for being the most widely used social science data-gathering technique.
Types of survey designs:
- Cross-sectional surveys collect data at one point in time.
- Longitudinal surveys gather data over multiple points to assess changes.

Components of Survey Research

Population refers to a general group with similar characteristics, while a sample is a subgroup selected to participate in the survey.
Surveys utilize a structured instrument, often a questionnaire, consisting of closed-ended questions for consistency in data collection.
Survey results analyzed using statistical techniques provide either descriptive analysis (numerical reports) or inferential analysis (comparative relationships).

Experimental Research

Aimed at establishing cause-and-effect relationships through the application of interventions on sample groups.
Groups involved include:
- Experimental group receives the treatment.
- Control group does not receive the treatment, allowing for comparison.

Components of Experimental Research

Respondents, referred to as groups, are differentiated into experimental and control.
Two main types of variables:
- Independent variable: the treatment that is manipulated to observe effects.
- Dependent variable: the outcome that reflects the effects of the independent variable.

Data Analysis and Interpretation

Data analysis plans are integral to survey design, involving descriptive methods for reporting survey findings and inferential methods for establishing relationships.
Analysis results help evaluate the effectiveness of the treatment in experimental research.

Key Terms

Correlational Research: type focused on identifying relationships between variables.
Statistical Techniques: methodologies used to process and analyze collected data.
Closed-ended Questions: standardized response options intended for quantitative measurement.
