Identify the major types of relationships between variables.

What will be an ideal response?

The major types of relationships between variables include:
?Positive or direct relationships, in which both variables vary in the same direction such that an increase in the value of one variable is accompanied by an increase in the value of the other variable
?Negative or inverse relationships, in which the variables vary in opposite directions such that an increase in one variable is accompanied by a decrease in the other variable
?Symmetrical relationships, in which change in either variable is accompanied by change in the other variable
?Asymmetrical relationships, in which change in one of the variables is accompanied by change in the other, but not vice versa
?Linear or straight-line relationships, in which the two variables vary at the same rate, regardless of whether their values are low, intermediate, or high
?Nonlinear relationships, in which the rate at which one variable changes in value is different for different values of the other variable
?Spurious relationships, in which a correlation between two variables is caused by a third or extraneous variable (the antecedent variable), rather than by their interrelationship
?Intervening relationships, which are caused by an intervening variable that is between the independent and dependent variables
?Suppressor relationships, which are relationships concealed by a suppressor variable that is positively associated with one variable and negatively associated with the other
?Causal relationships, in which two variables are related and vary together so that a change in one is accompanied by a change in the other, and vice versa
