$\"\"$

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 negative correlation and all the data points lie exactly on a straight line with negative 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 decreasing direction and the points will be on the line since $\"\"$ .

The graph which satisfies the above conditions is Graph $\"\"$ .

$\"\"$

Graph $\"\"$ is the correct choice.
