Study Notes

Types of Quantitative Research

Descriptive Research, Survey Research, Correlational Research, Quasi-experimental Research, and Experimental Research are the main types of quantitative research designs.

Descriptive Research

Purpose: Understand phenomena, situations, or populations without manipulating variables.
Focus: Identifies characteristics, categories, and trends.
Common methods: Case studies, observations, surveys.
Advantages:
- Provides detailed insights into research objectives.
- Easy to implement using surveys and observations.
- Generates representative data for broader population generalization.
Examples include consumer satisfaction levels, student perceptions, antivirus usage awareness, and bullying awareness.

Survey Research

Surveys are the most prevalent method for data collection from large populations.
Data analysis can be simplified using online survey software.
Types:
- Cross-sectional surveys gather data at one point in time.
- Longitudinal surveys collect data across multiple time points.
Advantages:
- Reaches wider audiences across various industries.
- Versatile for evaluating different objectives.
- Offers standardized data through structured questionnaires.
- Promotes respondent anonymity, encouraging honest feedback.

Correlational Research

A non-experimental method used to identify relationships between two variables without external influence.
Useful for recognizing patterns and trends, e.g., weather impact on ice cream sales.
Correlation types:
- Positive correlation: Both variables change in the same direction.
- Negative correlation: Variables change in opposite directions.
- Zero correlation: No relationship exists between variables.
Advantages:
- Establishes variable relationships without manipulation.
- Predicts outcomes and identifies trends based on observed data.
- Provides an ethical alternative when experimental manipulation is impractical.
- Cost-effective through data collected from existing sources.

Quasi-experimental Research

Aims to identify cause-and-effect relationships between independent and dependent variables.
Subjects are assigned to groups based on non-random criteria, making it suitable when true experiments are unethical or impractical.
Higher external validity due to real-world interventions compared to controlled lab settings.
Advantages:
- Allows comparison between different groups or conditions.
- High ecological validity enhances the applicability of findings to real-life scenarios.
- Practical and feasible approach in research settings.

Experimental Research

Also known as true experimentation, focuses on measuring the effects of independent variables on dependent variables using the scientific method.
Involves manipulating independent variables while subjects are randomly assigned to groups.
Advantages:
- High control over extraneous variables leads to strong internal validity.
- Facilitates replication of studies for verification of outcomes.
- Enables manipulation of variables to assess impacts on dependent variables.
