Study Notes

Introduction to Quantitative Research

Utilizes scientifically collected and statistically analyzed data to explore observable phenomena.
A phenomenon refers to any factual or situational aspect that requires further investigation.

Characteristics of Quantitative Research

Employs scientific methods for the design and collection of numerical data.
Analyzes numerical data using statistical techniques.
Data must be numerical and quantifiable, emphasizing the term "quantitative."

Examples of Quantitative Data

Student grades across various subjects.
Teen engagement hours on social media platforms.
Consumer preferences for soap packaging colors.
Daily Covid-19 patient recovery rates by region.

Data Transformation

Non-countable data can be converted into numerical formats for analysis.
Likert Scale can quantify subjective feelings into numerical choices for statistical operations.

General Features

Relies on large sample sizes to enhance statistical validity.
Data collection and analysis processes are objective, minimizing researcher bias.
Numerical data allows for the use of visual presentations like graphs, charts, and tables.
Fast data analysis is possible through statistical software, reducing time consumption.
Findings from samples can often be generalized to the broader population when proper sampling is conducted.

Strengths of Quantitative Research

Findings can be replicated to verify results.
Establishes causality between variables.
Generates numerical, quantifiable data to predict outcomes.
Facilitates quick collection and analysis of data using standardized instruments.
Maintains objectivity and enhances validity and reliability.

Weaknesses of Quantitative Research

Lacks depth in exploring complex problems or concepts.
Does not adequately explain human experiences or emotions.
Some information may not be quantifiable.
Research design is often rigid, limiting flexibility.
Participant responses may be constrained, potentially leading to inaccuracies.
Large sample sizes can increase data collection costs.

Types of Quantitative Research

Descriptive Design: Focuses on describing phenomena as they naturally occur without manipulating variables; suitable for answering "what," "where," and "when" but not "why."
Example: Investigating the frequency of physical activities among high school students during quarantine.
Correlational Design: Examines the relationship between variables without inferring causation.
