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.
It is important to test only one variable at a time during an experiment because if there is more than one, and there is change/s, you will not be able to identify which variable made the change. If you test only one, then you can identify the causing of the change and are able to measure of big or small the change was.
If you change two or more variables at the same time, you wouldn't know which one is having an effect on the outcome. There might also be no change - in that case, you don't know which one is affecting the results either way and how. By changing one at a time, you can precisely measure what changes happen and exactly how they are related.
It is usually not possible to test more than one variable at a time.
The dependent variable is the variable that can change in an experiment.
Yes, the one factor that a scientist changes during an experiment is also called an independent variable.
It (really) simplifies the math.
the part of an experiment that changes is called the variable.
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.

The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.

The independent variable is manipulated or chosen by the researcher and does not change during the study's course. Its purpose is to test how it affects the dependent variable in an experiment.
