TERMS TO KNOW
  • Strength

    The closeness of the points to the indicated form. Points that are strongly linear will all fall on or near a straight line.

  • Form

    The overall shape of the data points. The form may be linear or nonlinear, or there may not be any form at all to the points, if they form a "cloud."

  • Direction

    The way one variable responds to an increase in the other. With a negative association, an increase in one variable is associated with a decrease in the other, whereas with a positive association, an increase in one variable is associated with an increase in the other.
