What is correlative?

is when on a graph the dots are close together (Not quite.)

answ2. Correlation is the amount of a phenomenon which may be explained by one of the variables.
When plotted on a graph, if the data formed a straight line with no outlying points, that would illustrate a high degree of correlation. (between the x and y axes.)

If there were considerable scatter of your points from a line, then the correlation would be weak.

If for example I plotted the height of a class of boys, against their ages, I would expect a good correlation. In other Words, a large amount of the variability in height could be explained by the age variable.
