Positive Correlation in Psychology

Study Notes

Correlation Concepts

Correlation measures the relationship between two variables, indicating how they change together.
A correlation value ranges from -1 to 1, where:
- -1 represents a perfect negative correlation.
- 1 represents a perfect positive correlation.
- 0 indicates no correlation.

Types of Correlation

Positive correlation occurs when one variable increases, and the other variable also increases.
Correlation does not imply causation; a positive correlation does not mean one variable causes the other to change.

Examples of Positive Correlation

Increased study hours typically correlate with better exam performance.
The statement "the more hours in a day you stay awake, the less hours you spend asleep" does not exemplify a positive correlation.

Misconceptions About Correlation

A correlation of -0.7 is not of the same strength as a correlation of 0.7; they indicate similar strength but opposite directions.
A perfect positive relationship is represented by a correlation of 1, not suggesting causation.

Key Characteristics of Correlation

Every correlation has two defining qualities:
- Strength: Indicates how closely related the two variables are.
- Direction: Indicates whether the relationship is positive or negative.

Characteristics and Definitions

Correlation is a value that signifies how two variables relate to each other.
Misunderstanding can arise if one assumes that correlation necessarily indicates one variable causes the other to change.
