Study Notes

Nature of Quantitative Research

Quantitative research involves the use of numerical data to describe phenomena and infer relationships.
It is primarily focused on measuring and analyzing variables through statistical methods.

Types of Quantitative Research

Descriptive Research: Focuses on detailing characteristics of a specific group or phenomenon.
Exploratory Research: Seeks to explore and understand a problem without providing conclusive evidence.
Correlational Research: Investigates the relationship between two or more variables to identify patterns or correlations.
Experimental Research: Tests hypotheses through controlled experiments to establish cause-effect relationships.

Characteristics of Quantitative Research

Generalizability: Results can be applied to a larger population based on representative sampling.
Objectivity: Research is conducted without bias; data is observable and measurable.
Controllability: Researchers can manipulate variables to determine their impact on outcomes.
Replicability: Other researchers can replicate the study to verify results.

Research Variables

Independent Variable: The variable that is manipulated or changed to observe effects.
Dependent Variable: The outcome measured to assess the impact of the independent variable.
Extraneous Variables: Factors that may interfere with the relationship between the independent and dependent variables.

Hypothesis Testing

Formulating hypotheses is essential in quantitative research to define operational definitions and predictions.

Strengths of Quantitative Research

Capable of large-scale studies due to statistical analysis.
Data can be effectively presented in graphical or tabular formats.
Objective and measurable results lead to scientific credibility.

Weaknesses of Quantitative Research

Requires significant time and effort, especially with larger sample sizes.
Reducing observations to numbers can oversimplify complex phenomena.

Research Design Types

True Experimental: Randomized samples to identify cause-effect relationships.
Quasi-Experimental: Similar to experimental research but lacks randomization.
Non-experimental: Includes descriptive, correlational, and comparative designs.

Data Collection Methods

Surveys are widely used to gather quantitative data, which can include closed-ended questions for numerical analysis.

Important Definitions

Causal-Comparative: Also known as causal-comparative research, it compares two or more groups to identify differences.
Mediating Variable: This intervenes between independent and dependent variables.
Moderator Variable: Influences the strength of the relationship between the independent and dependent variables.

Notable Researchers

Creswell has defined quantitative research as a means for testing objective theories through relationships among variables.
Vanderstoep and Johnston emphasized correlational research as a measure of association between variables.
