This figure provides an illustrated example of a linear relationship. What does it mean? (Select all that apply.)
 
  a. As A becomes larger, B becomes larger.
  b. There is an indirect link between High and Concept A.
  c. As B becomes smaller, A becomes smaller.
  d. Concept A causes Concept B.
  e. The strength of the relationship is large because the portions of the concepts are explained.
  f. When A is absent, B is also absent.

Question 2

This figure provides an illustrated example of a curvilinear relationship. What does a curvilinear relationship signify? (Select all that apply.)
 
  a. The relationship is more complex than can be illustrated by a straight line.
  b. The most positive value of one variable is seldom associated with the most positive value or the most negative value of the other variable.
  c. The value of one variable cannot be predicted if the other is known.
  d. A relationship represented by an arc explains a large portion of the variation in the independent variable.
  e. The relationship between the variables is statistically significant.
  f. An increase in the value of one variable may be associated with either an increase or a decrease in the value of the other.

Answer to Question 1

ANS: A, C
A relational statement declares that a relationship of some kind exists between or among two or more concepts. Relational statements describe the direction, shape, strength, symmetry, sequencing, probability of occurrence, necessity, and sufficiency of a relationship. The strength of a relationship is the amount of variation explained by the relationship. In a linear relationship, the relationship between the two concepts remains consistent regardless of the values of each of the concepts. For example, if the value of A increases by 1 point each time the value of B increases by 1 point, the values continue to increase at the same rate whether the value is 2 or 200. The relationship can be illustrated by a straight line, as shown in the figure. In a curvilinear relationship, the relationship between the two concepts varies according to the relative values of the concepts. A negative relationship implies that as one concept changes, the other concept changes in the opposite direction.

Answer to Question 2

ANS: A, B, F
A relational statement declares that a relationship of some kind exists between or among two or more concepts. Relational statements describe the direction, shape, strength, symmetry, sequencing, probability of occurrence, necessity, and sufficiency of a relationship. The strength of a relationship is the amount of variation explained by the relationship. In regard to shape, most relationships are assumed to be linear. In a linear relationship, the relationship between the two concepts remains consistent regardless of the values of each of the concepts. The relationship can be illustrated by a straight line. Relationships can be curvilinear or some other shape. In a curvilinear relationship, the relationship between the two concepts varies according to the relative values of the concepts. This type of relationship is illustrated by a curved line, as shown in the figure.
