Identifying Variables in Experiments
Below are descriptions of experimental studies. For each of the descriptions, identify the
independent variable(s), the levels for each of the independent variables, the conditions, and the
dependent variable(s).
1.An organizational psychologist is interested in whether lowering the temperature in a factory
will increase productivity (i.e., number of products assembled). At the factory, there are three
rooms in which products are assembled. Each room is set at one of the following
temperatures: 60 degrees, 70 degrees, or 80 degrees.
Answer: Independent Variable: Temperature
Level of the independent variable: 3 (3 Rooms)
The condition: None
Dependant Variable: Productivity
2.A psychologist is studying the effects of steroids on the aggressive behavior of male rats.
Thirty rats receive twice-daily injections of a placebo, whereas another set of 30 rats receive
twice-daily injections of a steroid. For one hour a day, the rats are placed in a cage together
and all aggressive behaviors are recorded. For one week, lab assistants count the number of
aggressive behaviors recorded to determine whether or not there is difference between the
two groups of rats.
Answer: Independent Variable: Steroids
Level of the Independent Variable: 2 (2 groups of rats)
The Condition: The group of rats receiving placebo instead of steroid
The Dependent Variable: Aggressive Behaviour
3. A psychologist is examining the effects of alcohol on people’s driving ability under different
lighting situations. The psychologist randomly assigns participants to drink 2.5 ounces of a
non-alcoholic beverage, drink 2.5 ounces of an alcoholic beverage, or 5 ounces of an
alcoholic beverage. These participants are then randomly assigned to bright-light group or a
low-light group. Participants play a simulated driving game. The simulator is set up for
daylight driving in the bright-light group and set up for night driving in the low light
condition. While playing the simulator the number of incomplete stops and number of
obstacles hit are calculated.
Answer: Independent Variable: Alcohol, lighting
Level of independent variable: 5 (3 group for drinking alcoholic & non-alcoholic
beverages, bright-light & low-light group)
The condition: Group of people who have to drink 2.5 ounce non-alcoholic beverage
The Dependent Variable: People’s driving ability
