Study Notes

Quantitative Research Overview

Utilizes scientifically collected and statistically analyzed data to explore observable facts or situations.
Employs a scientific method for designing and gathering numerical data.
Analyzes data through statistical methods such as Pearson's r, t-tests, and analysis of variance.
Requires that all data obtained is numerical and quantifiable.

Characteristics of Quantitative Research

Large Sample Size: Ensures statistically significant results by gathering data from a wide-ranging sample.
Objectivity: Data collection and analysis are conducted with precision, free from personal biases or assumptions of researchers.

Data Analysis Techniques

Concise Visual Presentation: Data is expressed numerically, enhancing presentation through charts and tables for better interpretation.
Faster Data Analysis: Use of statistical tools streamlines the analysis process, saving time.
Generalized Data: Findings from samples can be extrapolated to the larger population, provided that the sample is sufficiently large and randomly selected.
Fast and Easy Data Collection: The methodology allows for swift data gathering using standardized research instruments, facilitating efficiency.
Reliable Data: Information is gathered and analyzed from a representative sample, boosting credibility for policymaking and decision-making.

High Replicability

High replicability enhances the validity of findings, minimizing the risk of false or hasty conclusions.
Focusing on statistical integrity ensures that results can be confidently shared and applied in various contexts.
