The correct answer is "**Dependent** clause.". **Independent** clauses express a complete thought and contain a subject and a verb. The farmer planted a tree. A **dependent** clause is a clause that isn't a complete thought, so it can't stand alone, even though it has a subject and verb. The independent variable describes the cause. The value of this type of variable remains unchanged by other variables in your study. The dependent variable describes the effect. The value of this variable is determined by the fluctuations induced by the researchers in the independent variable. Independent and dependent variables example.

Which variable is independent? a. distance traveled b. speed of the bike c.. This says that R 2, the proportion of variance in the **dependent** **variable** accounted for by both the **independent** **variables**, is equal to the sum of the squared correlations of the **independent** **variables** with Y. This is only true when the IVs are orthogonal (uncorrelated). In our example, R 2 is .67. The correlations are r y1 =.77 and r y2 = .72.
