Regression Coefficient of x on y

Regression coefficient of x on y is denoted by bxy.

Answer: B) bxy

Explanation:

Definition:
- The regression coefficient of x on y (bxy) represents the change in the dependent variable (y) for a one-unit change in the independent variable (x).

Interpretation:
- If the regression coefficient bxy is positive, it indicates a positive relationship between x and y.
- If bxy is negative, it shows a negative relationship.
- The magnitude of bxy indicates the strength of the relationship between x and y.

Calculation:
- Regression coefficient bxy is calculated using the formula: bxy = Σ(xy) / Σ(x^2)

Usage:
- Regression coefficient bxy is used in regression analysis to understand the impact of the independent variable x on the dependent variable y.
- It helps in predicting the value of y based on the value of x.

Conclusion:
Understanding the regression coefficient of x on y (bxy) is crucial in analyzing the relationship between variables and making predictions based on regression analysis.
