i dont know it means what
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.

Controlled experiment
No, a controlled experiment can have more than one variable. However, in a controlled experiment, only one variable is intentionally changed (independent variable) to observe its effect on another variable (dependent variable), while all other variables are kept constant (controlled variables) to ensure the validity of the results.

a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
a controlled experiment
A controlled experiment is when only one variable, the manipulated variable, is changed at a time to observe its effect on the dependent variable, while keeping all other variables constant. This approach helps to determine the specific impact of the manipulated variable on the outcome of the experiment.
