Draw a valid conclusion for that experiment.
Is it possible for an operational definition to be valid but not reliable
the definition for a controlled experiment is it test the effects of one factor
the answer is a experiment that is controlled
Repeatable

A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
And answer to an experiment
when he or she's conclusion is right
no it does not complt with the definition of a cheque and its not a valid negotiable instrument
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.
The definition of an experiment is a procedure that is done in order to make a discovery, test a hypothesis, or test a known fact. An experiment is often the testing of a scientific theory, although it can be applied to other fields as well, as long as it meets the criteria of the definition.
