An experiment in which only one variable is changed is a(an) __________ experiment.
2 answers:
An experiment that is only one variable that has changed is a controlled variable experiment.
the independent/controlled variable
is a variable that can be changed according to the purpose of the experiment
<h3><em>Further explanation </em></h3>
The development of chemistry begins with experiments that consist of chemical stages/processes. This method is a form of the scientific method that is commonly used by scientists in carrying out experiments.
Several experiments, trials, and errors will be carried out to test the hypothesis until the expected results are in the predetermined problem at the outset.
Variables, which can be determined in 2:
- 1. independent variable
, which is a variable that can be changed according to the purpose of the experiment
- 2. fixed variable, i.e. variable whose value is constant and observed to determine changes in independent variables
We can control independent variables according to the results of the experiments to find conditions that have the most optimal results so that the goals of the problems that have been set will be achieved.
The continuous investigation is so that the control variables are not out of the problem boundary
So the right choice is a controlled variable
