because the variable has many steps
The term for an experiment in which only one variable is changed at a time is called a controlled experiment. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment.
Changing only one variable in an experiment allows researchers to clearly determine the effect that variable has on the outcome. If multiple variables are changed, it becomes difficult to identify which variable is responsible for the observed results. This helps to ensure that the results are reliable and can be accurately interpreted.
the investigator only changes one variable in an experiment because they need to see how that one variable reacts. if you wanted to see how the dependent variable changed but changed the independent variable you would not see how the one variable reacts.
The one variable that is changed in an experiment to test a hypothesis is called the independent variable. This is the variable that the researcher manipulates or controls to observe its effect on another variable, known as the dependent variable.
When only one variable is changed at a time in an experiment or study, it allows researchers to isolate the effects of that specific variable on the outcome. This method helps in understanding how individual variables impact the results and avoids confusion from multiple variables interacting simultaneously.

You can have more than one variable, but it would take longer to solve.
a controlled experiment
The one variable that is purposely changed to test a hypothesis is manipulated variable
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.
Indpendent variable
a controlled experiment
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.
Changing only one variable in an experiment allows researchers to clearly determine the effect that variable has on the outcome. If multiple variables are changed, it becomes difficult to identify which variable is responsible for the observed results. This helps to ensure that the results are reliable and can be accurately interpreted.
