    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.
