The linear relationship between two variables
The slope of the line of best fit
How closely the data fit a defined curve
The sum of the residuals from each data point
The coefficient of determination can have values from –1 to 1.
The coefficient of determination can be applied to any curve.
The coefficient of determination can be applied to any straight line.
The coefficient of determination is the variation in y explained by variation in x, divided by the total variation in y.
The magnitude of the correlation coefficient determines the strength of the linear relationship
The sign of the correlation coefficient determines whether the relationship is positive or negative
