A concept is an abstract term describing an object, idea, or phenomenon, such as the concept of "self-esteem" which describes how individuals perceive and value themselves.
A theory is a set of principles that explain a phenomenon, for example, the theory of evolution explains how species change over time through natural selection.

Research Methods

Quantitative method focuses on numbers and objective data, for example, a survey asking students how many hours they study per week to understand its impact on their grades.
Qualitative method uses words and focuses on feelings, for example, interviews with students to explore their feelings and experiences regarding school bullying.

Variables

A variable is a quality that can change and take different values.
Independent variable is the thing being tested or changed, for example, the amount of sunlight in an experiment to understand its impact on plant growth.
Dependent variable is the outcome or result being measured, for example, the growth of the plants in the experiment.
Extraneous variable is an other factor that could affect the outcome, for example, caffeine consumption in a study on how music affects concentration.
Demographic variable is a characteristic like age, gender, etc., for example, age, gender, and grade level in a survey to understand students' favorite extracurricular activities.
