Study Notes
Quantitative Research Overview
- Quantitative research focuses on numerals and their ability to describe phenomena or infer relationships.
- It is essential for scientific inquiry due to its capability to test hypotheses and analyze the relationship between various factors known as variables.
Characteristics of Quantitative Research
- Controllability: Allows for understanding a specific relationship under controlled variables.
- Generalizability: Results are based on larger sample sizes to represent the population.
- Objectivity: Data is observable and measurable using structured instruments.
- Replicability: Other researchers can replicate the study to achieve similar outcomes.
Strengths of Quantitative Research
- Utilizes statistical methods for analysis, making data more meaningful and interpretable.
- Large-scale research is feasible due to easy administration of data collection methods.
- Data can be effectively presented using graphical or tabular forms for better comprehension.
Weaknesses of Quantitative Research
- Requires substantial time and effort for larger sample sizes, which can increase costs and extend research timelines.
- Statistical analysis demands expertise; lack of statistical skills can hinder study validity.
- Numerical reduction of observations may oversimplify complex phenomena, lacking depth in addressing the 'why' and 'how'.
Types of Quantitative Research
- Divided into Experimental and Non-Experimental categories, chosen based on the research topic and nature of the problem.
- Descriptive Research: A non-experimental design focusing on describing factors or phenomena, often utilizing surveys for data collection.
Key Concepts
- Independent Variable: The variable that is manipulated during the study.
- Dependent Variable: The variable being measured that relies on the independent variable.
Examples of Quantitative Research
- Identifying factors contributing to food spoilage through surveys.
- Measuring the growth of plants based on different soil types, water amounts, etc.
- Analyzing test scores across different demographics to identify achievement gaps.
Research Evaluation
- Reading an abstract can reveal the study's quantitative nature.
- Presence of statistical indicators (e.g., p-values) signifies a quantitative approach.
- Understanding variable types (discrete, continuous) is crucial for quantification.
