Correlation and regression calculator
Enter two data sets and this calculator will find the equation of the regression line and correlation coefficient. The calculator will generate a step by step explanation along with the graphic representation of the data sets and regression line.
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.
The values of X and their corresponding values of Y are shown in the table below:
$$ \begin{array}{c|ccccc} X & 1 & 2 & 3 & 4 & 5 \\ Y & 4 & 8 & 9 & 11& 16 \end{array} $$Find a Pearson correlation coefficient.
