Question

Correlation coefficient: A measure of the magnitude and direction of the relationship (the correlation) between two variables. The closer the correlation coefficient is to +1 or -1, the stronger the relationship. The units of length in the SI system, from smallest to largest, are as follows: nanometer, millimeters, centimeter, meter, kilometer. Therefore, the centimeter is smaller than a kilometer, but the nanometer is not larger than a centimeter. The scale of a graph is what you mark on the axes. It's the relation between the units you're using, and their representation on the graph i.e., the distance between marks. An order of magnitude is a factor of ten. A quantity growing by four orders of magnitude implies it has grown by a factor of 10,000 or 10⁴.
