You can put this solution on YOUR website! Make a scatter plot of the data below.
x: -5,-3,-3,0,1,2,5,6
y: -4,12,10,-6,8,0,3,-9
Describe the correlation of the data. If possible, fit a line to the data and write an equation of the line.
The linear correlation is bad,
because the points don't appear to
fall in a straight line.
The correlation coefficient is
merely -.3839067252 which in
absolute value is not a good
fit, for it isn't close to 1
at all. The best fitting line,
called the "regression line"
has this equation:
y = -.7624565469x+2.035921205
On the graph that line is:
I found this line on the TI-84. If you want to know how,
post again.
