Introduction to Variables

Quantitative research focuses on numeric observations called "variables."
Differentiation between discrete and continuous variables is crucial for statistical analysis.

Discrete Variables

Defined as whole, countable numbers with finite values between any two points.
No fractional values exist (e.g., ½ word is not applicable).
Common examples include:
- Number of complaints
- Number of boxes
- Number of competitions
- Number of cubes

Continuous Variables

Defined as numbers that can be infinitely divided into smaller, fractional parts.
Examples include measurements such as:
- Height
- Weight
- Distance
- Time
Continuous variables allow for a range of values without gaps.

Importance in Research

Identifying and defining variable types is essential for selecting appropriate statistical analysis methods.
Misclassification can lead to incorrect data analysis and interpretation.

Research Project Overview

Focuses on the importance of collaborative learning as a unified nation.
Emphasizes the significance of practical research in high school education.
Relevant for students in various strands: STEM, ABM, HUMSS, and ICT (TVL Track).

Activity Components

Students should complete a personal information section: name, grade, section, and date.
Identification of the research strand: STEM, ABM, HUMSS, or ICT.
Activity title and learning target should reflect the objectives of the project.
Encourage proper citation by including references with author, title, and page numbers.

Hypothesis-Driven Research Exercise

Aimed at developing critical thinking and research skills through controlled experiments.
Students should suggest a new hypothesis-driven research topic for exploration.
Controlled experiments focus on manipulating one variable while keeping others constant to ascertain causal relationships.
Encourages students to think creatively and scientifically in forming research questions.

This quiz introduces the concept of variables in quantitative research, emphasizing the differences between discrete and continuous variables. Understanding these distinctions is crucial for proper statistical analysis and data interpretation. Test your knowledge on the types of variables and their significance in research.
