Transcript Notes: Quantitative Research Concepts

A prayer recited at the start of class addressed to Heavenly Father and Jesus Christ.
Expressions of gratitude for life and for another day.
Request for guidance to be instruments for good, enlightenment of the mind, and strength to participate in the subject today.
Concluding with the name of Jesus Christ, Amen.

Presented by Giancarlo I. De Guzman as Subject Teacher.
Focus: Characteristics, strengths & weaknesses of quantitative research, and the kinds of quantitative research.
Central theme: Understanding what quantitative research is and how it is structured
(Note: Page title includes multiple subtopics to be covered in this lesson).

RESEARCH - It is derived from the Middle French "recherche", which means "to go about seeking".
It is the process of systematic inquiry that entails:
- collection of data;
- documentation of critical information;
- analysis and interpretation of that data/information,
all in accordance with suitable methodologies set by specific professional fields and academic disciplines.

It is an objective, formal, systematic process in which numerical data are used to quantify or measure social phenomena.
It uses numbers in stating generalizations about a given problem or inquiry.
The numbers are the results of objective scales of measurements of the units of analysis called “variables”.

$1$ . It requires large number of respondents.
$2$ . It is costly.
$3$ . Many information are difficult to gather using structured research instruments.
$4$ . If not done correctly, data from questionnaires may be incomplete and inaccurate.

$1$ . Descriptive Research - It is defined as a research method that describes the characteristics of the population or phenomenon that is being studied.
$2$ . Correlational Research - It is a type of non-experimental research method, in which a researcher measures two variables, understands and assesses the statistical relationship between them.

$3$ . Experimental Research - is a study that strictly adheres to a scientific research design. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared.
$4$ . Evaluation Research - is a systematic process used to assess the effectiveness, efficiency, and impact of a program, project, or intervention.

Summary of key concepts and connections

Quantitative research is defined as an objective, formal, systematic process using numerical data to quantify social phenomena, with variables representing units of analysis.
Core characteristics include objectivity, clearly defined outcomes, large samples, structured instruments, the possibility of replication, prospective usefulness, and reliance on numerical data.
Strengths emphasize objectivity, reproducibility, use of statistical tools, and ease of numerical analysis.
Weaknesses highlight the need for large samples, cost, challenges with structured instruments, and potential data quality issues if not designed properly.
The main typologies of quantitative research covered include descriptive, correlational, experimental, and evaluation research, each with distinct aims and methodologies.
The content includes an explicit foundational note that research is derived from the French term involving seeking, and it is performed within established methodologies across professional and academic disciplines.
An assignment prompts students to prepare for an upcoming individual activity, indicating practical application of the lesson.
