In a controlled experiment, there is typically 1 independent variable that is changed or tested to observe its effect on the dependent variable. Having multiple independent variables can complicate the results and make it difficult to determine which variable affected the outcome. Therefore, the best answer is 1.
An independent variable is a variable that is tested in a controlled experiment. How many independent variables does a controlled experiment have?
1
2
As many as the scientist wants
An independent variable is not needed for a controlled experiment.

In a controlled experiment, there is typically 1 independent variable. This allows the scientist to isolate the effects of that variable on the dependent variable, making the results clearer and more interpretable. Therefore, the correct answer is 1.
