dependent: remembering how to get through the maze
BRAINLIEST IS GREATLY APPRECIATED :)
Experimental design includes controlled, dependent and independent variables. The removal of the brain part is the independent, and the memory of getting through the maze is the dependent variable.
What are dependent and independent variables?
Dependent variables are the parameters that have to be tested or measured by experimenting. In the case of the rats, the memory has to be tested for remembering the path through the maze.
Independent variables are the parameters and conditions that an experimenter varies to analyze and study the effect. In experiments with rats, the removal of the brain part is the independent variable.
Therefore, the removal of the brain part is independent, and memory of the maze path is the dependent variable.
