Why does it make sense for scientist to test just one variable at a time in an experiment?

Answers

Answer 1

Answer:

If you run an experiment with multiple variables, you won't be able to determine which variable ultimately led to the change.

What is the one variable at a time in an experiment?

Testing a single variable at a time enables you to assess the outcomes of your experiment to see how much a particular adjustment influenced the outcome.

If you test two variables simultaneously, you won't be able to determine which one caused the outcome.

Only one variable (the independent variable) is altered at a time in a science experiment to see how it affects the dependent variable.

Other variables that are either constant or vary throughout the experiment but are not thought to impact the results may also be measured by the researcher.

Therefore, scientist use to test just one variable at a time in an experiment.
