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.
It is best to follow the process that way. The results would be less confusing as the situation with multiple variables tested simultaneously.
A controlled experiment test one factor at a time.

You are performing a controlled experiment.

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.
It depends what you mean by that. But in an experiment that is made up of several tests, one factor at a time must be changed in order to rule out each possible factor until only one remains. Also test conditions may change if performed on a different day. Hope that helps you!!
a fair test
