If you test more than one variable you don't know which one caused the changes.
Changes in the independent variable will cause changes in the dependent variable.
In an investigation, the variable that you change is called the "independent variable." It is the factor that is manipulated to observe its effect on another variable, known as the dependent variable. The independent variable is crucial for establishing cause-and-effect relationships in experiments.

The dependent variable.
In the investigation depicted in the drawing, the variable that changes is the independent variable. This is the variable that is deliberately manipulated or changed by the researcher to observe its effect on the dependent variable. The dependent variable, on the other hand, is the variable that is being measured or observed for changes as a result of the manipulation of the independent variable. In this investigation, the independent variable is likely being altered to see how it impacts the dependent variable.
The variable under investigation is typically referred to as the "dependent variable" in a research study. This is the variable that is being measured or observed to determine how it is affected by changes in another variable, known as the independent variable.
I will change the independent variable in my investigation. This variable is the one I manipulate or control to observe its effect on the dependent variable.
The manipulated variable in an investigation is called the independent variable. It is the variable that is intentionally changed or controlled by the researcher to observe its effect on the dependent variable.
If you test more than one variable you don't know which one caused the changes.
A testable variable is what you test several times for a scientific investigation or medical investigation.
I can make a pretty good guess at the answer if you'll tell me something about the investigation. Like, for example, are you studying crime in big cities, carbon dioxide in sea water, the sex life of mosquitos, voting patterns in the south of Mexico, etc. ?
