Step 1

The correlation coefficient, often denoted by 'r', is a numerical measure that quantifies the degree of statistical relationship between two variables. The value of 'r' ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect Show more…

Key Concepts

Correlation Coefficient

The correlation coefficient is a statistical metric that quantifies the linear relationship between two variables. Its value ranges from -1 to 1, indicating the degree to which the variables move in relation to each other.

Strength of Association

The absolute value of the correlation coefficient reflects the strength of the association between the variables. Values closer to 1 represent a strong linear relationship, while values near 0 imply a weak or no linear association.

Direction of Association

The sign of the correlation coefficient indicates the direction of the relationship. A positive sign means that as one variable increases, the other variable also tends to increase, whereas a negative sign indicates that as one variable increases, the other tends to decrease.
