A moderator variable is a third variable that changes the relationship between the independent variable and dependent variable in an important way. It is also sometimes referred to as an interaction variable or a conditional variable. A spurious variable refers to a variable that appears to be related to the dependent variable but is actually not related once other variables are taken into account. A contingency variable is another term for a moderator variable. An outlier variable refers to a single observation or data point that falls outside the normal range of values for the other observations in the data set.
