Frequently Asked Questions
What is correlation coefficient?
The correlation coefficient (r) measures the strength and direction of the relationship between two variables, ranging from -1 to +1.
What does R-squared mean?
R-squared (R²) indicates how well the regression line fits the data, showing the percentage of variance explained by the relationship.
How do I interpret the regression line?
The regression line equation (y = mx + b) shows the predicted y-value for any x-value, where m is the slope and b is the y-intercept.
