Answer to Question 1

Answer: A confound is a variable that systematically changes along with the independent variable, potentially leading to a mistaken conclusion about the effect of the independent variable. Random assignment is the best way to help avoid confounds in experiments.

Answer to Question 2

Answer: An independent variable is the variable that is manipulated by the experimenter. A dependent variable is the variable that is measured by the experimenter. The independent variable is considered the cause, and the dependent variable the effect.
