The corresponding correlation coefficient is .
Generally the correlation coefficient, , has a specific range of values is
.
never lies outside this range.
is perfect positive correlation and all the data points lie exactly on a straight line with positive gradient.
likewise is perfect negative correlation.
Since is perfect positive correlation and all the data points lie exactly on a straight line with positive gradient.
These have the cloud of data points and a trend line fitted to show the direction of the data.
\The line looks like in the increasing direction and the points will be on the line since equal to .
The graph which satisfies the above conditions is Graph .
Graph is the correct choice.
