Final answer:
In an industrial psychology study on temperature and productivity, the independent variable is the temperature of the packing rooms, and the dependent variable is the workers' productivity. The experimental condition involves lowering the temperature to 65 degrees, while the control condition maintains the standard 76 degrees.
Step-by-step explanation:
An industrial psychologist's study investigating the impact of room temperature on productivity involves identifying various variables. In this study, the independent variable is the temperature of the packing rooms, specifically the difference between the lowered temperature (65 degrees) and the usual company temperature (76 degrees).
The dependent variable is the productivity of the workers, measured by the number of products packed. This is what the psychologist expects to change as a function of the room temperature.
The experimental condition is the packing room with the lowered temperature of 65 degrees, where the experimental manipulation is taking place.
Meanwhile, the control condition is the packing room with the usual company temperature of 76 degrees, which serves as a comparison group to the experimental condition. This control group remains unaltered in terms of temperature.
