What is the main difference between a concept and a variable?
What is the main difference between a concept and a variable?
1. Measurability
2. Reliability
3. Subjectivity
4. Objectivity
The correct answer is 1-Measurability
- A concept is an abstract idea or phenomenon. It is not directly measurable.
- A variable is a measurable characteristic of a concept. It can take on different values.
For example, the concept of intelligence is abstract and cannot be directly measured. However, we can measure different variables that are related to intelligence, such as IQ test scores, academic performance, and problem-solving skills.
Here are some examples of concepts and variables:
- Concept: Intelligence
- Variables: IQ test scores, academic performance, problem-solving skills
- Concept: Poverty
- Variables: Income level, access to food and shelter, education level
- Concept: Happiness
- Variables: Life satisfaction ratings, positive emotions, negative emotions
In research, it is important to be able to clearly define the concepts and variables that are being studied. This helps to ensure that the research is reliable and objective.
Therefore, the main difference between a concept and a variable is measurability.
