Why is it important for other variables in an experiment to be controlled?
A
To allow for more variables to be tested simultaneously.
B
To make the experiment more time-consuming.
C
To increase the complexity of the experiment.

In an experiment, the independent variable is the one that is changed or controlled to test its effects on the dependent variable.
Controlling other variables, known as controlled variables, is crucial because it ensures that any observed changes in the dependent variable are directly due to the manipulation of the independent variable.
If other variables are not controlled, they could introduce confounding factors, which might lead to incorrect conclusions about the relationship between the independent and dependent variables.
By keeping all other variables constant, the experimenter can attribute any changes in the dependent variable solely to the independent variable, thus ensuring the validity of the experiment.
This approach helps in maintaining the integrity of the experimental results, making them reliable and reproducible.
