Answer:

controlled experiments

Explanation:

Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.

ANSWER:

The controlled experiments are the ones in which all variables are identical except for one.

EXPLANATION:

  • The experiments are conducted only by bringing about changes to one variable rather than all variables.
  • Controlled experiments are used to test hypothesis in which changes are brought about by adjusting only one variable rather than all the variables used in the hypothesis experiment.
  • The results of these experiments vary with the changes that are brought about in the one dependent variable.
