Answer to Question 1

The independent variable is the type of learning (group or traditional) and the dependent variable is how well the information is learned. The independent variable is manipulatedparticip ants are randomly assigned to the two conditions. The study utilizes the experimental method.

Answer to Question 2

The independent variable is the amount of nicotine (the smoking versus nonsmoking groups) and the dependent variable is concentration level. The independent variable is a participant variable because we are using participants who either chose to smoke or not to smoke. The study utilizes the quasi-experimental method.
