Enter two data sets and this calculator will find the equation of the regression line and corelation coefficient. The calculator will generate a step by step explanation along with the graphic representation of the data sets and regression line.

Example 1:
Consider the following set of points: {(3 , 4) , (2 , 3) , (7 , 11)}
a) Find the regression line for the given data points.
b) Plot the given points and the regression line.
Set up the formExample 2:
The values of x and their corresponding values of y are shown in the table below:
$$ \begin{array}{cccccc} X & ~1~ & ~2~ & ~3~ & ~4~ & ~5 \\ Y & ~4~ & ~8~ & ~9~ & ~11~& ~16 \end{array} $$a) Find the least square regression line in the form $ ~~y = a \cdot x + b $.
b) Plot the given points and the regression line.
Set up the formPlease tell me how can I make this better.
