QUANTITATIVE RESEARCH GROUP 1 & 2
What is Quantitative Research?
Quantitative research is a systematic investigation that focuses on gathering
numerical data and using statistical methods to analyze it. This kind of research
helps us measure variables and find patterns or relationships between them.
(Creswell, J. W., & Creswell, J. D., 2018)
It aims to explain phenomena by collecting data that can be quantified and
subjected to mathematical analysis. Through this process, researchers can test
hypotheses and make predictions.
(Babbie, E. R., 2020)
Quantitative research is commonly used in the natural and social sciences
because it provides objective results that can be generalized to larger populations
when using proper sampling techniques.
(Saunders, M., Lewis, P., & Thornhill, A., 2019)
Characteristics of Quantitative Research
1. Objective - Quantitative research is objective, meaning it seeks to eliminate
personal bias by focusing purely on numerical data and measurable facts rather than
opinions or feelings.
(Creswell, J. W., 2014)
2. Structured Research Instruments - It uses structured tools such as surveys,
questionnaires, and tests to ensure consistency and reliability in the data collection
process.
(Kabir, S. M. S., 2016)
3. Large Sample Sizes - This research involves large sample sizes so that results
can be statistically valid and representative of the larger population.
(Given, L. M., 2008)
4. Measurable Variables - Variables in quantitative research are measurable, which
means they can be expressed in numbers and evaluated using mathematical or
statistical analysis.
(Punch, K. F., 2013).
5. Clearly Defined Research Questions - A clearly defined research question is a
focused and specific query that guides a research project. It should be clear,
concise, and easily understood by anyone reading it, outlining the exact purpose and
scope of the study.
6. Replication - Replication
Quantitative research emphasizes replication, which involves repeating a study
under the same or nearly identical conditions—such as using the same methods and
measurements—to confirm whether the original findings are consistent. This process
helps to establish the reliability and credibility of results by ruling out chance, bias, or
anomalies
7. Generalizability to the Population
Quantitative research is easily generalizable to the population when it employs
probability sampling and sufficiently large, representative samples, enabling
researchers to extend findings from the sample to the broader population with
confidence. Ensuring sample representativeness and methodological rigor enhances
the external validity and practical relevance of the results
