Document Summary

Part a: review of chapters 1-10 (10 @ 2 = 20 points) For each of the 10 statements below, indicate whether the statement is true or false. Explain your decision about the truth of the statement with reference to the bolded terms. A1: an operational definition of a dependent variable is also known as a confounding variable. An operational definition refers to the procedures for measuring or manipulating a variable. A dependent variable is an outcome measure related to or caused by an independent variable. A confounding variable is a variable that systematically covaries with an independent variable so that it is not possible to know whether the confounding variable or the independent variable leads to changes in the dependent variable. Therefore, the statement is false because a confounding variable is not a dependent variable. Sometimes a positively skewed distribution is the result of a floor effect.
