The best interpretation of the slope of the regression line is the height increases, on average, by 0.48 meter each year.
The regression line is also called the line of best fit and it is calculated by statisticians using the least squares method.
The regression line describes the quantitative relationship between the dependent and the independent variables. This is useful in making meaningful extrapolations from the line.
The general form of the regression line is y = b + ax where;
y is the independent variableb is the y intercepta is the slope of the graphx is the independent variableGiven the specific regression line
predicted height = 0.29 + 048 (age)
The independent variable is the age of the tree and the dependent variable is the height of the tree.
Given the regression line, it is reasonable to say that the best interpretation of the regression line is that the height increases, on average, by 0.48 meter each year.
