If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
It is advantageous for scientists to test only one variable at a time during an experiment because if you change all variables at once, you will not be able to tell which variable is responsible for the observed results.
The factor that scientists change or manipulate during an experiment is called the independent variable. It is the variable being tested to see how it affects the dependent variable, which is the variable being measured or observed. By manipulating the independent variable, scientists can analyze its impact on the dependent variable and draw conclusions about their relationship.

The independent variable changes during an experiment.
The independent variable changes during an experiment.
It (really) simplifies the math.
The independent variable is the variable that is changed during an experiment.
The dependent variable is the variable that can change in an experiment.

Variables are purposely changed during an experiment to observe the effect it has on the outcome or dependent variable. Scientists manipulate the independent variable to determine its impact on the dependent variable, allowing for a systematic investigation of cause-and-effect relationships. This helps to establish a clear understanding of how different factors influence the results of the experiment.
Dependent variable.
a variable can throw the whole experiment off and will have to be repeated.
The variable that is observed during an experiment is called the dependent variable. It is the outcome or response that is measured and affected by changes in the independent variable.
