Quantitative Research

Quantitative Research

Research based on measurement or quantity, using scientifically collected and statistically analyzed data to investigate observable phenomena.

Numerical Data

Data that is generally easier to collect than qualitative descriptions, often expressed in numbers.

Large Sample Size

A characteristic of quantitative research that helps obtain more meaningful statistical results.

Objectivity

The principle that data gathering and analysis in quantitative research are done accurately and without personal bias.

Concise Visual Presentation

The ability to present numerical data through graphs, charts, and tables for better interpretation.

Faster Data Analysis

The use of statistical tools in quantitative research that allows for quicker data analysis.

Generalized Data

Data from a sample that can be applied to the larger population if sampling is done correctly.

Fast and Easy Data Collection

The efficiency of collecting data using standardized research instruments in quantitative research.

Reliable Data

Data that is credible and trustworthy for policymaking, derived from objective analysis of a representative sample.

High Replicability

The ability to repeat quantitative research to verify findings, enhancing validity.

Advantages of Quantitative Research

Includes objectivity, generalizability, conclusive cause-and-effect relationships, and ease of data analysis.

Disadvantages of Quantitative Research

Lacks depth in exploring problems, does not explain human experiences comprehensively, and may lead to inaccurate responses.

Importance of Quantitative Research

Its role in discovering solutions to problems and influencing decision-making in various fields.

Variables

Elements or characteristics considered in research that can be measured or manipulated.

Continuous Variables

Variables that can take infinite values and can be divided into smaller increments.

Discrete Variables

Variables that are finite and countable, often classified as nominal, ordinal, or dichotomous.

Independent Variables

Variables known to cause change and influence dependent variables.

Dependent Variables

Variables that are the result or outcome influenced by independent variables.

Extraneous Variables

Factors that may influence the outcome but are not manipulated by the researcher.

Control Variables

Constant factors in research that may influence the results.

Research Topic

A well-defined subject essential for successful research, requiring careful consideration.

Research Title

A concise description of the research study that captures the reader's attention.

Background of the Study

Contextual information that informs the reader about the research topic.

Research Gap

An unexplored area of a topic that requires further investigation.

Statement of the Problem

A clear explanation of the issue or challenge the research aims to address.

Research Questions

Questions that clarify and specify the research problem, guiding data collection and analysis.

Characteristics of Good Research Questions

Feasibility, clarity, significance, and ethical considerations.

Scope and Delimitation

Specifies the coverage and exclusions of the study, including variables and populations.

Significance of the Study

The potential impact and relevance of the research findings on existing knowledge.

Definition of Terms

An annex that contains technical and operational definitions used throughout the research.
