The variables that you keep the same in an experiment are called "controlled variables" or "constants." These are factors that are deliberately kept unchanged to ensure that any observed effects can be attributed to the independent variable being tested. By controlling these variables, researchers can maintain the integrity of the experiment and ensure valid results.
A hypothesis can be tested by an experiment
There are many different things that are measured and tested by the data collected in an experiment. Color changes are one thing that can be measured and tested for example.
The factor that is being tested in an experiment is called a variable. The factor that is measured or observed is called the dependent variable.
Hypothesis or postulate .
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.

It depends on the experiment. Normally only one is tested at a time because they can affect the experiment. Variables are tested in a controlled experiment to see whether they affect the outcome and also how.

A constant is a condition that is controlled to remain consistent throughout the experiment. It is used to ensure that any changes observed are a result of the variables being tested, rather than external factors.
