by a controlled experiment When seeking an answer to a problem, one might take the problem and test one factor at a time in order to find that answer by a process of elimination.
A controlled experiment test one factor at a time.

A variable test?
Two limitations of a t-test are you can only use one factor at a time and you can only use two levels at a time. You have to watch out for the Type 1 error because it increases with simultaneous tests.
compaction factor test is better than slump test,because compaction factor test should have own compaction wight,so correct value will be find out from compaction factor test.........
the definition for a controlled experiment is it test the effects of one factor
One must pass a written test and a driving test if one is a first time applicant or has not renewed for an extended period of time.
Because, if he changes several variables at the same time, he will not know which of them caused the result of the experiment to change. He would have to test again, changing one variable at a time.
