Types of Quantitative Research
- Four primary types: Survey/Descriptive, Correlational, Causal Comparative/Quasi-Experimental, and Experimental Research.
Descriptive Research
- Focuses on detailing the characteristics and components of a population or phenomenon.
- Aims to find general attributes of existing situations and determine their frequency.
Survey Research
- Used to gather data from groups through sampling from a larger population.
- Provides numeric descriptions of trends and opinions by studying a sample.
- Collecting data from hard-to-reach populations (e.g., illegal immigrants, sex workers) presents unique challenges.
- Self-reported information can lead to inaccuracies in questionnaires.
Characteristics of Quantitative Research
- Employs standardized methods to enable replication and comparability.
- Tends to have inflexible research designs once initiated.
Strengths of Quantitative Research
- Minimizes researcher bias and enhances reliability through objective measurements.
- Utilizes statistics for generalization of findings from samples to populations.
- Allows for identification of relationships among variables and determination of cause-effect relationships in controlled settings.
Weaknesses of Quantitative Research
- Often lacks detail compared to qualitative methods, potentially oversimplifying complex issues.
- Relies on the assumption that samples represent the population adequately.
Role in Different Fields
- In business: Assists in product design, target market analysis, and distribution strategies.
- In STEM: Aids in investigating health trends, intervention outcomes, and cost analyses in healthcare.
- In humanities and social sciences: Addresses social problems felt by communities and individuals.
Variables in Research
- Defined as measurable factors that can change based on certain conditions.
- Include various characteristics like age, gender, or performance metrics.
Types of Variables
- Discrete (Nominal or Ordinal) and Continuous.
- Discrete variables have limited distinct values, whereas continuous can take on an infinite number of values.
Research Reflection
- Encourages students to identify societal problems and propose research topics.
- Highlights the importance of understanding objectives behind conducting research.
