1. Quantitative research focuses on numerical and statistical analysis of data to answer questions. 2. It involves collecting and studying numerical data using mathematical operations to analyze relationships between variables. 3. Quantitative research aims to produce objective, precise measurements and in-depth analysis of data to understand people, events, and phenomena in measurable terms.

1. QUANTITATIVE RESEARCH

2. QUANTITATIVE RESEARCH
Expressions like numerical forms, objective thinking,
statistical methods, and measurement signal the
existence of quantitative research. One word that
reflects the true nature of this type of research is
numerical.
Quantitative research makes you focus your mind on
specific things by means of statistics that involve
collection and study of numerical data.

3. • You use mathematical operations of addition,
subtraction, division, and multiplication to study and
express relationships between quantities or
magnitudes shown by numbers or symbols. Involving
measurements and amounts, quantitative research
seeks to find answers to questions starting with how
many, how much, how long, to what extent, and the
like. Answers to these questions come in numerals,
percentages, and fractions, among others.

4. Characteristics
• Characterized by objectiveness, in which only the real or
factual, not the emotional or cognitive existence of the
object matters greatly to the artist, quantitative research is
analogous to scientific or experimental thinking. In this case,
you just do not identify problems but theorize, hypothesize,
analyze, infer, and create as well. Quantitative research
usually happens in hard sciences like physics, chemistry,
biology, and medicine; qualitative research, in soft sciences
such as humanities, social sciences, education, and
psychology, among others.

5. Classification
• Experimental Research - True experimental, quasi-
experimental, single subject, and pre-experimental. Quasi-
experimental comes in several types such as: matched
comparative group, time series, and counterbalanced quasi-
experimental.
• Non-experimental Research - survey, historical,
observational, correlational, descriptive, and comparative
research.

6. Importance
• The importance of quantitative research lies greatly in the
production of results that should reflect precise
measurement and an in-depth analysis of data. It is also
useful in obtaining an objective understanding of people,
things, places, and events in this world; meaning, attaching
accurate or exact meanings to objects or subjects, rather
than inflated meanings resulting from the researcher’s bias
or personal attachment to things related to the research.

8. Quantitative explanatory questions
• Structurally, quantitative explanatory questions must contain
an independent variable and dependent variable and they
should ask about the relationship between these variables.
The standard format for an explanatory quantitative research
question is: “What is the relationship between [independent
variable] and [dependent variable] for [target population]?”
You should play with the wording for your research question,
revising it as you see fit. The goal is to make the research
question reflect what you really want to know in your study.
